National Performance Management ProgramTransportation System Condition Assessment

Pavement and Bridge Targets Consideration and action regarding a

recommendation to the MPO Policy Board regarding MPO support of TxDOT pavement and bridge targets for Calendar Year 2024 for National Highway System (NHS) facilities in accordance with requirements from the Fixing America’s Surface Transportation Act (FAST).

14

Tracking Condition is a Federal Requirement for States & MPOs For State DOTs, failure to achieve target would require

shift of federal dollars to improve conditions Requirement for National Highway System only

Interstates Other Freeways Principal Arterials 11% of regional lane-miles, 60% of regional travel

MPO tracks condition for all arterial & collector roads within MTP

Pavement & Bridge Condition Performance

16

4-year (2018-2022) statewide performance targets set by TxDOT in 2018 MPO Policy Board voted to mostly support TxDOT targets Region-specific target for percent “good” non-interstate NHS

Oct. 2020, TxDOT submitted mid-performance period progress report to FHWA

Five of the six statewide pavement and bridge performance targets adjusted for 2022

MPOs have 180 days to either reaffirm support for adjusted targets or set new regional targets

2022 Adjusted Pavement and Bridge Performance Targets

18

For pavement condition, Interstate performance is more stringent than other NHS facilities Interstate System IRI, Cracking, & Rutting or Faulting Good pavements must be good for all 3 Poor pavements = poor for 2 of the 3

All Other NHS facilities Int’l Roughness Index (IRI) only

Definitions Monitored for 1/10 mile segments for each direction All Pavements

International Roughness Index (IRI)

Asphalt Pavements Rutting Condition Cracking Percentage

Concrete Pavements Cracking Percentage Joint Faulting


20

International Roughness Index (IRI) Standard universal score 94 or less = good Greater than 170 = poor

NOTE: Rough roads do not necessarily equal a poor pavement condition


21

Rutting Condition in Asphalt Pavements TxDOT Definition Applies only to Interstate Depth less than 0.2 inches = good Depth greater than 0.4 inches = poor

NOTE: Rutting is not generally an issue for concrete pavements


22

Cracking Condition in Asphalt Pavements TxDOT Definition Applies only to Interstate 4% or less = good Greater than 20% = poor


23

Cracking Condition in Jointed Concrete Pavements TxDOT Definition Applies only to Interstate 4% or less = good Greater than 18% = poor


24

Cracking Condition in Continuously Reinforced Concrete Pavements TxDOT Definition Applies only to Interstate 4% or less = good Greater than 10% = poor

Facility Type 2020 Poor Lane-Miles



Interstate 0.0% 0.3% 0.2%Non-Interstate 6.99% 14.3% 14.2%

Note: In 2018, the MPO adopted a separate regional target for Non-Interstate pavements in good condition at 48.0%. Since the percentage of these facilities being rated as good increased significantly, MPO staff is recommending support of the adjusted TxDOT targets.

26

MPO Staff Recommendations Support adjusted 2022 state targets for both

Interstate and Non-Interstate Conditions Regional conditions better than statewide average IH-35 reconstruction should further improve

Interstate pavement conditions


27

Unlike pavement condition, no difference between Interstate vs. Non-Interstate measures % of NHS bridge deck area in good condition % of NHS bridge deck area in poor condition

Required Elements (Score 1 to 10) Superstructure Condition Substructure Condition Bridge Deck Condition

Score of 7 or greater = ‘good’ Score of 4 or less = ‘poor’ Good bridges have all elements with score > 7 Poor bridges have at least one element with score < 4

Scheduled Work IH-35 reconstruction (ongoing)

All bridges either have been or will be reconstructed or have significant rehabilitation

Increases ‘good’ deck area for IH-35 from 57.7% to 93.3% Overall ‘good’ deck area increases from 46.57% to 55.09%

Several other bridges will be removed from this calculation because they are coming off the NHS system

No other bridge work in the pipeline to impact 2022 targets


30

MPO Staff Recommendations Support adjusted 2022 state targets Regional conditions better than statewide average IH-35 reconstruction will replace, reconstruct or

eliminate several bridges previously rated as ‘fair’
