ESAL for a typical asphalt paving
ESAL for a typical asphalt paving
(OP)
For a 3" thick asphalt wear course, over an 8" thick base, over an 8" thick sub-base; what is the ESAL loading for this flexible pavement? One geotech engineer say roughly 1,000,000 ESAL. I think that is too high. I have used a design software and came up with 122000 ESAL. Does this sound about right? Trying to get a feel for pavement design as it is not my area of expertise. Thanks very much.

In general, the SN you get from 3" TOTAL asphalt (wear and binder) and 6" subbase will be good for the 500,000 to 2M range.

I used SpectraPave2 from Tensar Corporation, I did get SN of 3.02 but it is telling me that the allowable traffic load (ESAL's) is 122000. This does not agree with what was said. Could you guys help explain? Thanks very much.

"We did not perform any California Bearing Ratio tests on the surficial soils at the project site. However, based on our experience we recommend a CBR value of 6 to 8 for 8-inches of lime-fly ash stabilized sandy/silty clays overlying the fill soils. A higher CBR may be obtained by increasing the thickness of stabilized soils."
Regarding the design life, that is another subject by itself. I posted the subject on this board and it ranges from 10 to 15 years. I think I am going to design it for 10 years. I did an estimated traffic calculation using common sense only. I used 1000 cars (0.36 ESAL per day), 1000 pick-up trucks (2.27 ESAL per day), 10 delivery trucks (1 ESAL per day), 50 semi trailer truck (67.5 ESAL per day), and a crane every other truck (13.3 ESAL per day); I got 308170 ESAL's for 10 years. By the way, the road is located inside an industrial plant / chemical plant. Thanks in advance.
