CA ratio = % half sieve - % PCS 100 - % half sieve

As the CA ratio INCREASES, VMA and Voids INCREASE, but compactibility DECREASES.

A change of 0.20 is ~= 1% change in VMA or Voids.

It should generally be in the range of 0.80-0.95.

As the CA ratio DECREASES, segregation susceptibility INCREASES.

Overly high values can be difficult to compact in the field and can cause "tenderness" because the coarse fraction doesn't want to "lock up".

This ratio is primarily controlled by the VOLUME blend of CA(s) (cells C52:F52) and/or the gradation of the CA(s) being used.

It still provides an indication of segregation susceptibility.

For Coarse-Graded mixes:

DECREASE of 4% is ~ = INCREASE of 1% VMA or Voids, or vice-versa.

*******************************For Fine-Graded mixes:

INCREASE of 6% is ~ = INCREASE of 1% VMA or Voids, or vice-versa.

This value is primarily controlled by the % CA LUW (cell D38).100.0
THG: The primary purpose of first determining a combined blend with the VIRGIN aggregates ONLY, is to establish the desired blend by VOLUME of coarse and fine for the corresponding mix TYPE (coarse-graded or fine-graded), which is reflected in the ORIGINAL PCS value and is a function of the % CA LUW (cell D38).

The designer should then try to match the ORIGINAL PCS in the RAP blend as close as possible to maintain the same approximate volumes of coarse and fine.4.75

FAc ratio = % SCS % PCS

As the FAc ratio INCREASES, VMA and Voids DECREASE.



Low values can be difficult to compact in the field and should NOT coincide with a low FAf ratio.

High values are generally in or near the restricted zone and can relate to tenderness for mixes with an excess of natural sand.

This ratio is primarily controlled by the VOLUME blend of FA(s) (cells G54:J54) and/or the gradation of the FA(s).

**********************************************************For Fine-Graded mixes:

Although this ratio is NOT used for fine-graded mixes, it does give an indication of the coarsenss or fineness of the "blend" PASSING the ORIGINAL PCS.

Values around 0.55 or greater generally indicate that this portion of the "blend" is ALSO fine-graded.

In other words, the volume of material PASSING the NEW PCS is greater than the volume of voids that exist in the NEW coarse fraction between the ORIGINAL PCS and the NEW PCS.1.0001.18100.0100.00.600

FAf ratio = % TCS % SCS

As the FAf ratio INCREASES, VMA and Voids DECREASE.



Low values can be difficult to compact in the field and should NOT coincide with a low FAc ratio.

High values generally indicate mixes with high dust to effective AC ratios and overly high mortar stiffness.

This ratio is primarily a function of the 0.075mm value (cell H57) if MF or BHF's are being used and/or the 0.075mm values of the various individual aggregates.

********************************************************************For Fine-Graded mixes:

Although this ratio is NOT used for fine-graded mixes, it does give an indication of the coarsenss or fineness of the NEW fine fraction in the "blend" PASSING the ORIGINAL PCS.


In other words, the volume of material PASSING the NEW SCS is greater than the volume of voids that exist in the fine fraction between the NEW PCS and the NEW SCS.1.0000.075100.0100.0% CA LUW
THG: For Coarse-Graded mixes, this value should generally be within the range of 95-105%.

As this value INCREASES, VMA and Voids INCREASE - coarse aggregate interlock starts to absorb compaction energy, which lessens the compaction of the fine fraction.

High values, especially those that exceed 105%, can be difficult to compact in the field and normally coincide with high FAc and/or FAf ratios (a fine fraction that is overly compactible), or a coarse fraction that is breaking down (degrading) under compaction.

CAUTION: There MAY be occassions where values above 105% are necessary and can be utilized successfully in the field, such as blends that have a low CA ratio, where the coarse fraction is more compactible than normal. However, these blends are SUSCEPTIBLE to segregation. Also, instances where the coarse fraction is more compactible than normal due to shape, strength or texture characteristics, may also require higher than normal values to DECREASE the compaction energy transferred to the fine fraction. This is often evident in below normal values for the Loose and Rodded Voids of the given CA.

****************************************************************************************************

For Fine-Graded mixes, this value should generally be equal to or less than 90%.

As this value DECREASES, VMA and Voids INCREASE - coarse particles that are primarily floating in the overall blend and filling voids are removed and replaced with multiple fine particles that have voids between them.

As this value DECREASES, compactibility DECREASES in the lab and the field, by moving the overall blend away from the maximum density line on a 0.45 power chart. Low values normally coincide with high NEW FAc and/or NEW FAf ratios (a NEW fine fraction that is overly compactible).100.0% FA RUW

NEW CA ratio = % NEW half sieve - % NEW PCS % ORIGINAL PCS - % NEW half sieve

As the NEW CA ratio INCREASES, VMA and Voids INCREASE.



It is not NMPS dependent as with coarse-graded mixes, because the "coarse" fraction (i.e. the material between the ORIGINAL PCS and the NEW PCS) is a much smaller amount in a fine-graded mix, as compared to what typically exists above the PCS in a coarse-graded mix.

This ratio is primarily controlled by the VOLUME blend of FA(s) (cells G54:J54) and/or the gradation of the FA(s) being used. However, it can also be affected by a CA, if that particular material has a gradation that contributes a significant amount of it's material to the sieves between the ORIGINAL PCS and the NEW PCS.ERROR:#DIV/0!Bulk Spec Gr

Step #5: In a 37.5mm Nominal Maximum Particle Size mix, the CA/FA break (Primary Control Sieve) is the 9.5 mm. Determine the amount of "Fine" aggregate that each Coarse aggregate contains by weight and the amount of "Coarse" aggregate that each Fine aggregate contains by weight.

The % passing the 9.5 mm sieve in the #2-CA=0.0%These percentages represent the material in each respective aggregate that is considered to be the "opposite" fraction of material (I.e. "Fine" aggregate in the CA or "Coarse" aggregate in the FA).



The % retained on the 9.5 mm sieve in the #1-FA=100.0%




Step #6: Make corrections to each individual aggregate according to the percentages by WEIGHT of the "opposite" fraction that it contains, while maintaining the original VOLUME blend of CA to FA.
