Dear Mr. Powelh
We have performed a geotechnical investigation for the referenced
project (our report number B-5-0244, dated 05/20/85), and in this report
we recommended that a four (4) inch thick concrete pavement be used in
areas where light vehicular traffic is expected. The four (4) inch
pavement was derived at using the following design parameters.
- Expected pavement life: 15-20 years
- Average 10 heaviest wheel loads: 8 kips
- Number of applications per day: 10
- Number of equivalent 18 kips; single axle loads: 14,000
- Traffic Number (based on the above): 10 or less
- Design Number (DN): 2.5
The following structural numbers were used for the pavement components:
- Concrete: 0.5
- Select Filh 0.12
- Natural Soils: 0.08

A pavement cross section consisting of four (4) inches of concrete and
12 inches of select fill will have a structural number of 3.44, which
exceeds the required design number of 2.5.
We trust the information provided herein is sufficient for your use.
