Kentucky Transportation Center Research Report
To determine pavement thicknesses from design charts and tables, it is necessary to know only the EAL's (equivalent axle loads), the CBR of the subgrade soil, and the modulus of elasticity of the bituminous concrete. Charts permit selection of pavement structures employing alternative proportions of bituminous concrete and crushed stone base. Total thickness varies according to the proportions chosen. It is implicitly intended that the selection of alternative structures be based on engineering considerations, such as 1. estimates of comparative construction costs, 2. compatibility with cross section template and shoulder designs, 3. uniformity or standardization of design practices, 4. highway …
