RP51 Construction of corridor cross sections

2 User guide

1. Introduction

Program RP51 “Construction of corridor cross sections” is part of package

ROADPAC. It serves for complex processing of roadway for solving construction

of corridor cross section in alignment range. Program is controlled by a

preprocessing program.

1.1 Function of program

Program computes - constructs corridor cross sections, uses actual input data and

results data of programs RP43-cross section arrangement, RP31- vertical alignment

and RP27-Terrain cross sections. This program can be followed by programs

RP53- Drawing of corridor cross sections, RP83-Perspective views on designed

corridor and RP71- Calculation of cut-fill earthworks etc.

1.2 Processed data files

Input files

.V51 - file of actual input data of program RP51

.STR - terrain cross sections file

.SNI - vertical alignment file

.SKR - cross section arrangement file (grading details)

Output files

.V51 - probably modified file of input data

.L51 - Listing

.SPR - corridor cross sections file

.O51 - graphic informative and checking file

2. Input data

The input data are processed by filling and editing of tables or to click on controls

placed on forms appearing on the computer display. Display operation is described

in special user guide. See chapter “Introduction”. Forms usually incorporate

common control part, graphical part if it is useful and input data part. A Picture

box, if is placed on form, serve to display immediate results. Input data of program

corridor cross section of road are prepared in several blocks. Each block includes

one or more tables. Some of them can be omitted (according to a type of task).

Tables are placed on several tabs. Program offers immediate graphic verification of

current processing. Currently computed cross-sections are displayed at ones.

Practice with program is next:

Specification of parameters ► calculation ► visual checking.

Alternative specification of parameters ► calculation ► visual checking.

2.1 Corridor cross sections- modification.

After program start an information form is shown on the screen with displayed

urgent input files state. It means urgent for successful calculation. If any of light

bulbs not shining proper defect must be eliminated – urgent input files must exists

and must be available.

An interactive control program proceeds assigning of task parameters as well as

program running. After push down button „Assemble corridor cross section“ the

main form of preprocessing program is shown.

After push down button „Templates" the function enables easier access for

newcomer users. From Menu form are accessible basic elements (items) of corridor

cross section specification. Selected items are then used for assembling of input

data. Than main form of control program is shown likewise for further edition and

modification of task parameters. Previous data stored in V51 if co-exists are

substituted. For appropriate modification if requested is necessary to use standard

regimes. More detailed description of all program possibilities and features see

follows.

User guide 9

1.1. P10-2 = 0 (P10-3 = 0) indicates unpaved shoulder crossfall (formation under

shoulder), in case that gradient ascending towards centreline. When gradient

descending towards centreline, gradient of shoulder will be done 8% out,

gradient of formation will always extended.

1.2. P10-2 > 0 (P10-3 > 0) indicates construction of assigned gradient P10-2

(P10-3). When crossfall of pavement is greater than P10-2 and also greater

than P10-3, pavement gradient will be extended. If gradient is descending

towards centreline, opposite gradient will be done.

1.3. P10-2 < 0 (P10-3 < 0 means extension of pavement gradient for shoulder

crossfall and formation crossfall under pavement if gradient ascending

towards centreline. If pavement gradient is descending towards centreline,

opposite gradient will be done.

2. Congestion is always performed together with ditch in cut. If there is not

done code P11-1 which is preferred (program alert by warning about formal

error).

3. Widening will be performed if embankment is higher than P11-3. Height

of embankment HK is measured according to note of code P30-1. Widening

is not radically performed if type of embankment P20-1 = 6 is set. In case of

embankment without ditch is HK measured from terrain.

4. Widening will be performed without respect on fact either it is cutting or

embankment.

Meaning of parameter Standard

Notes:

1. Left and right part must be always

specified even when a side limits are

specified.

2. Upper part of central reserve can be

given by maximally two Break Points.

If both parameters P12-1 are positive,

one BP lays on the left and the next one

on the right side.

When parameter P12-1 < 0 is given, actual BP point (L or R) is located on opposite

side.

3. Points will be omitted by specification of parameter P12-1 = 0 together with

P12-2 = 0. See picture-standard where is break point omitted on the left.

4. Both points can be omitted this way. Then central reserve will be a

connection line of inner edges of pavement (inner points of grading details).

5. To design of central reserve as point on centreline set parameter P12-1 on the

left or on the right by value 0.01.

6. Formation in central reserve is defined by position of drains on the left and

on the right (P12-4) and by gradient leading to drainage from edge of

formation (P12-3). In case that drains on the left and right are assigned,

gradient between them is designed automatically.

7. Gradient P12-3 and also axial distance P12-4 are always specified positive.

Value P12-4 = 0 indicates suppression of drain. Both drains can be

suppressed this way. When axial drain in central reserve is needed set one of

parameters P12-4 = 0.01, second P12-4 = 0.


User guide 13

8. Modification of central reserve must be always specified on two rows for the

left (L) and right (R) side in same segment of chainage. When condition of

program is not kept, shows mistake of data.

9. Drain can be assigned either directly in centreline of roadway (see picture

No 5) or on the left or right from centreline (distance >= 0.25m). Position is

modified at other specification.

Parameters Settings in case of an additional lane placing in central reserve:

Central reserve can overlap the centreline in case of insertion of left-turning lane

but there are necessary to keep some modifications in construction of central

reserve. Basic meaning of parameters P12-X stays without change. Also principles

for their use are not changed.

When central reserve exists and any parameters P12-X are not given, following

default values are used:

a) When right half of central reserve wide is 1.0 m at least, parameters in

accordance with previous documentation are used:

on the left: on the right:

P12-1 = 0. m P12-1 = 0.75 m

P12-2 = 0. m P12-2 = 0.06 m

P12-3 = 6. % P12-3 = 6. %

P12-4 = 0. m P12-4 = 0.75 m

b) When the condition is not fitted and left half of central lane wide is 1.0 m at

least, symmetrical parameters are used:

P12-1 = 0.75 m P12-1 = 0.0 m

P12-2 = 0.06 m P12-2 = 0.0 m

P12-3 = 6. % P12-3 = 6. %

P12-4 = 0.75 m P12-4 = 0.0 m


User guide 15

c) When neither this condition is fulfill, solution without gutter (connection of

both edges of central reserve) and with drain in half of width central reserve is used:

P12-1 = 0.0 m P12-1 = 0.0 m

P12-2 = 0.0 m P12-2 = 0.0 m

P12-3 = 6. % P12-3 = 6. %

P12-4 = D m P12-4 = 0.0 m, when central point D lays on the left, or

P12-4 = 0.0 m P12-4 = D m, when central point D lays on the right.

In case that distance from point D (drain) to nearer edge of formation is smaller

than 0.25 m, drain is overlooked and ending points of formation are connected by

line. Ending points of pavement cannot layover and also ending points of formation.

This is controlled by program CROSS SECTION ARRANGEMENT. If ending

points of pavement or formation gets over central reserve then are written in "big

protocol" with opposite sign. In this case beginning points of pavement or

formation do not lay on centreline but they are always identical.

In new version program RP51 allows solving of following 12 types of central

reserves in crown (combination of parameters P12-1 and P12-2) and 8 type of

central reserves in formation (combination of parameters P12-3 and P12-4):

Variants of crown solution for dual carriageway:

4 1 point of central reserve on the left 10 all central lane on the left

5 1 point of central reserve on the right 11 ditto, connection of points

6 1 point of central reserve on centerline 12 solution with curbs

For dual carriageways, where is placed left-turning additional lane (on one side or

on both directions), only one solution is possible:

For roof crossfall on lane is add point at centreline by extension of carriageways

crossfall and it will be automatically vertically placed at the level of theoretical

horizontal alignment. The crossfall of carriageway continues without interruption at

one-sided crossfall.

In such case central reserve must be coded by giving parameters for both sides of

carriageway by this way:

P12-1 = 0.0 m P12-3 = 0.0

P12-2 = -1.0 m P12-4 = 0.0

Omission of parameters P12 would appear adding of default values according to

paragraphs a) till c) that is not right solution.

2 Drain only on the right 6 Whole of central reserve with drain on the left

3 Drain only on the left

4 Without drain 7 Ditto without drain

5 Drain on central line 8 All central reserve without drain

9 Ditto, without drain

Test on error No 746 “drain out of central reserve” has been added in new version.

Drain is placed inside central reserve, into position given by parameters P12-4. Zero

value of parameter indicates omission of drain. Exact position in central reserve is

dimensioned by assignment P12-4 = 0.01 (on the left or right or both). When

assigned position is out of central reserve, warning No 746 is shown. When

assigned position is identical with inside edge of pavement, drain is moved towards

center of central reserve up to 0.27 m so it will be placed inside of central reserve.

Notes:

1. For type P20-1 = 1, 2 and 4 can max. 6

various gradients and 5 thicknesses of

layers (or comparative heights) be

assigned. 2 gradients and 1 thickness

(SV) must be minimally specified. All

other parameters are omitted in this

case. (Use space in proper table cell.)

None of specified parameters can be

equal to 0.

2. Broken slopes in accordance with ČSN

broken slopes generally program usually starts to construct from terrain.

When foot ditch type 2 is made, broken slope starts from bottom of foot

ditch.

3. Height of embankment HN is measured from terrain. In case of ditch type 2;

from bottom of ditch, in case of ditch type 3 from bench (compare pictures

for code P30-1). Height HN must be given on table row in ascending order.

4. In this case IP with terrain is not argument of construction end. In such case

construction ends at IP point with side limits borderline, on elevation P20-3.

Solution will be performed also in case that points A,C or BO lays under

terrain. Simultaneously cannot be assigned code P50-1=6. Point BO on

borderline cannot lay higher then point A. In such a case is performed

standard solution (P20-1=0). When parameter P20-1=6 is specified program

does not perform conditioned widening of shoulder. When edge line A-BO

does not intersect formation, the formation will be extended until borderline

by same gradient as before.

Generally: When embankment does not intersect extended terrain, the terrain is

ended vertically in a point AN. Terrain is extended horizontally on 50 m.

Scheme and notes of embankment shapes: Ending of embankment on the bottom

depends on type of foot ditch (see later). Drawn scheme are usually without foot

ditch but they can continue into ditch type 1,2 or 3.

Explanatory notes to ditch design:

1. Ditch bottom can be defined:


User guide 33

1.1. In absolute terms (by level) on type 92 line

1.2. By relative depth with reference to roadway (point A)

1.3. By relative depth with reference to formation (point C)

Mode 1 is always preferred to Mode 2 and Mode 3

Mode 3 is applicable only for type A2, B2 or C2.

2. It cannot be foreseen whether the ditch bottom will appear above or below

formation (otherwise it would be impossible to design londitudinal gradient of

ditch bottoms by means of code 92). Therefore, every ditch type (A, B, C) is

possible construct in two variants according to pictures 12, 13 and 14. User can

specified only combination of those two types. First in case that ditch bottom is

above formation and second in case that bottom is below formation.

3. Only following combinations are possible:

3.1. When bottom depth from roadway edge is specified (P60-2 = x0x) or

bottom elevation specified by absolute height above sea level:

A1 - C2 code 00x

B1 - C2 10x

C1 - C2 20x

A1 - A2 30x

B1 - B2 40x

3.2. When bottom depth from formation is specified (P60-2 = x1x), only

two solutions are possible A2, B2 or C2 (bottom is always under formation).

Following codes are specified:

C2 code 01x , 11x or 21x

A2 code 31x

B2 code 41x

4. Elevation of bench behind the ditch can be defined as the last digit of the three-

4.1. from ditch bottom (always defined as positive value), 3.digit = 0

4.2. from point A (positive upward, negative downward), 3.digit = 1

5. Position of drain (parameter P63-1) refers to hard shoulder outer edge (edge No

special shapes in grading details, than it is simultaneously the last point of

grading details on roadway. Special shapes, if are specified on roadway, has no

influence on position of drain. In case that drain given this way should lie

nearer to centreline than last point of formation (includes special points on

formation), drain is moved at last point of formation.

Edges rounding:

According to ČSN 73 6101 rounding of cut

and fill edges are performed at top and foot of

slope. According to examples in MD ČSR

(VL2, 95.04) there are several modes, how to

perform rounding is explained:

1. According to VL 311.01 rounding will

be performed only in topsoil layer that will be

chamfered into curve of length max. 2.00 m

on heal or on edge. Range of topsoil stripping does not change unlike to case when

rounding is not performed.

2. According to VL 301.03 and 301.04 width of topsoil stripping and topsoil

spreading is increased by length of tangent curvature (max. 2.0m). Resulting shape

is the same in both cases, only calculations of cut-offs are influenced, firstly topsoil

stripping and topsoil spreading. In second case are costs on both elements increased

a lot. In program RP51 parameter P90-1 (code of rounding type) is updated. Old

versions of Roadpac did not use rounding (code P90-1 = 0).

This method is also used at rounding of type 1. Chamfer has no influence on topsoil

spreading and topsoil stripping cut-offs volumes. At drawing sections by program

RP53 are those rounding ignored. For computations of land acquisition range the

rounding must be respected in assignment of adequate distance of bench marks.

At code P90-1 greater than 0, the curvature is designed according to item 2.

Practically it is performed by inserting of 5 points (broken polyline on slope

simulated curve) instead of slope IP with terrain.

It will be used in cut-fills of topsoil spreading and stripping, it is also drawn in

cross section drawings (Attention on specified elevation and slopes description,

remedial points are given by elevations and also by slope description). During land

acquisition range calculation is specified distance of bench marks from end of

curvature.

Emergency announcers

Emergency announcers are established in area of shoulder, thus construction of road

bed in their proximity has no continuity with Cross section arrangement file, nor

with program RP43. Therefore it is convenient, that all changes related with

specification of emergency announcers are

implemented to program RP51 and SPR file. Still

it is necessary to reflect further results in program

RP53 (drawing of cross-sections), RP71

(calculations of building volumes) and in drawings

of layouts in ROADCAD system.

Comparison of sample sheets of safety fences made

of steel and made of concrete results in conclusion

that island for emergency announcer installation

can be always modeled as widening of shoulder in


50 User guide

shape of trapezoid and that its shape can be always defined by up to 6 parameters

for both sides.

Dialogue program SI51C will set defaults that correspond to standard steel safety

fence. User will specify only chainage S1 and side (L, R) and program will offer

defaults on a new row, and other parameters, if they are atypical, parameters can be

modified by user. For standard safety barrier on single carriageway road are defaults

(by measurement from sample list): S2 - S1 = 46.8 m, P1 = 4.7 m, P2 = 19.9 m, P3

= 2.15 m, P4 = 1.40 m

Comment: in opposite direction you also specify S2 > S1 (like with all

parameters). But P1 and P2 values are always plotted in direction of travel, thus in

opposite direction - from S2 chainage in direction towards S1!

This way of coding has an advantage that it is reflected during generation of cross

sections in all sections in sector between S1 and S2 and the program will easily

calculate required width of shoulder for every position of section on a basis of

entered parameters.

In area between chainage S1 and S2 will be nominal width of shoulder (marked by

dashed line) increased by widening, which will be linearly interpolated between

values: zero, P3, P4 and zero.

For precise capturing of shape of road bed in closeness of emergency announcer,

program RP51 will generate, besides standard sections in regular chainage, another

4 sections in chainage S1, S1+P1*0.001, S1+P2*0.001 and S2 (inversely in

opposite direction). For such sections is defined neither surfacing nor terrain, but

both can be interpolated from closeness sections of SKR and STR files. Once the

sections are constructed and stored in SPR file, all follow-up programs will respect

them; thus they is used for layout design, building volumes and drawings SI53 -

there you can specify by code, whether to draw all sections or just so called

"tabular", i.e. with regular step specified in 001 and 002 data. Naturally, such

additional sections are not included among tabular ones.

If a new section merges with some of existing ones with tolerance less than 4.9 cm,

no new section will be created and code of announcer (value 1024 in WP code) will

be added to existing code of WP section

Specification checking:

- Two adjacent announcers on the same side may not overlap (in opposite

direction they can)

- P2 > P1, neither P1 nor P2 must be smaller than S2 - S1

- S2 > S1 (applies to all parameters in general).


User guide 51

- S2 - S1 is at least 1 m (the function will be available also for other

modifications, e.g. stacking ground of spreading materials or other construction -

e.g. for traffic lights

- P1 is at least 0.1 m and S2-S1 - P2 is also at least 0.10 m. In the event of

widening by step the program will thus generate no section pairs in identical

chainage, but section pairs in 10 cm distance. Even in this case only one section

may be identified to existing section - the closer one.

- widening of P3 and P4 is positive and up to 100 m as a maximum (again

possibility to use it for other purposes, e.g. parking place or operational areas).

Limitation

Four new sections will be generated only in mode of creation of Cross section

arrangement file and terrain files (Code1 = 1); in correction mode (Code1 = 3) there

will be applied increased widening of shoulder in sector between S1 and S2, but

further sections will not be created. This mode does not read Cross section

arrangement file, but it generates Cross section arrangement reversely from SPR file

and in such events the interpolation of surfacing would be enormously complex.

Besides that, in this mode the program copies all sections situated out of specified

correction area.

In mode of selection of sections according to list (Code3 = 1) the program creates

only such new sections that fall in area delimited in a list.

Program RP51 does not work with dBase on line bat with copies of templates only.

Range of central reserve samples

Pavement

For specification of pavement layers will tables placed on Tab Pavement –

construct intended.

At the right side of tab is placed table of templates localization along alignment.

Templates of single carriageway roads are valid for both sides of pavement

construction. For roads with central reserve must be specified templates separately

for left and right side of carriageway. Templates should be different on the left and

right side in number of layers and its shape.

Side L/ /R Column are blank if pavement construction is on the both sides of

roadway in case of carriageway with or without central reserve concurrent.

Chainage of validity from (km) Chainages must be concur on both sides and

segments may not overlapping itself. If no template will be in any segment specified

no construction will be stored in corridor cross section file in this segment.

Chainage of Validity to (km) ditto.

Template name Up to 10 characters can be assign as name of template.

Names of template must exactly correspond to names stored in list of used

templates. (See next picture.)

all six end-capping types motives are

visible.

Layers count . A count of layers is specified including subbase layer

(At most 7 layers can be specified + subbase, it means total 8)

Roadway Type Specify dual carriageway or single carriageway roadway. One of

possibility is chosen.

Table of pavement layer specification

Table is ready to accept specification of 8 layers. Lower layer is always subbase

layer and it has different properties during construct process according Subbase

cap code.

Name of layer can have up most 8 characters, is used for description of layers in

listings of subsequent RP45, RP47 a RP72 programs.

Layer thickness (m) thickness of proper layer must be specified except subbase

layer thickness.

Edge offset (Neither adjacent to the left/ right side of carriageway or to the

shoulder side or central reserve side respectively). Offset is measured

horizontally from the origin point:

The origin point is the inner edge of carriageway in case of road with

central reserve and outer edge of carriageway.

The origin point is the left edge of carriageway in case of road without

central reserve and right edge of carriageway.

Layer gradients are specified in a way 1: x, Enter value x

By buttons “Open dBase of templates”, “Add template to dBase”, "Select

template from dBase" and “Save (s) template dBase” user can maintain his input

data and dbase.

Open dBase of templates. This is intended for modification of templates in dBase.

Before using of this editor user must open dBase Standard core dBase is placed

after installation at directory ....roadpac\sablony\pavement.dbr User can establish

by “Save (s) template dBase” its own dBase in any directory on his computer.

After dBase opening it is possible to click on button "Select template from

dBase". The proper form „List of templates“ is shown afterwards. In the left side

of form is placed listbox filled by templates. After click on any of them in the list is

selected template drawn in picture and table is load to program.

This table is intended for visualization of selected templates no modification is

permitted. For specification of new templates and modification of it is intended

basic tables placed on Tab, template is copied to it by click on button "Fill table".

4. DESCRIPTION OF OUTPUT LISTING

The output listing is generated in the course of the computation in the 'road' .L51

file. Its printing can be controlled from the main menu.

Output listing includes protocol about current calculation inclusive error reports.

Other part of output listing is given by requirements stated in control data:

Small listing contains basic data about cross sections, which are included in files

CORRIDOR CROSS SECTIONS. Signs used in small protocol are explained by

this protocol itself.

Full listing is comment listing of detailed data about all cross sections. Coordinates

of terrain, surface of roadway, pavement and formation, data about topsoil

spreading, data about position of ditches in cut or fill, side limits are printed etc.

5. Warning messages

The program differentiates between fatal errors, which usually cause program

termination with unusable results and formal errors that are handled by alternate

solution. Fatal errors are marked by *** in reports and formal errors are marked by

**. The following table contains list of warning messages and comments to

alternate solution:

In the first part of program the input data are controlled. In this part fatal errors

appear that construction of cross sections is not done and file SPR is not created.

In the second part of program cross sections are designed continuously according to

chainage. In this part the fatal errors usually do not occur, program try to created

spare solution everywhere, in case of fatal error the cross section is omitted. In

protocol are simultaneously written cross section chainage, number of indicated

errors at its creating and summary of error reports. Maximally can be indicated 19

reports, if there is more error than 19 in current cross section it is taken are fatal

error and section is not inscribed to SPR.

In second part of program are errors signed by stars and by code.

** L error in left half of cross section

** P error in right half of cross section

** S error in central reserve

** G error in terrain and in geology

The following table contains list of error messages and comments to alternate

solution:
