Pavement Aashto: ac_base to cement_treated_base
AASHTO pavement design material properties including layer coefficients, drainage coefficients, and modulus values for flexible and rigid pavement design
| material id | description | layer coefficient | layer type | material name | max thickness in | min thickness in (in) | notes | typical modulus MPa (MPa) | typical modulus psi (psi) |
|---|---|---|---|---|---|---|---|---|---|
| ac_base | Asphalt concrete base course | 0.34 | base | Asphalt-Treated Base | 8 | 3 | a2=0.34; plant-mixed asphalt-treated base | 2,760 | 400,000 |
| ac_dense_graded | Dense-graded hot-mix asphalt surface course | 0.44 | surface | Dense-Graded HMA | 6 | 1.5 | a1=0.44 per AASHTO Table 2.5; Superpave or Marshall mix design | 3,100 | 450,000 |
| ac_open_graded | Open-graded friction course for surface drainage | 0.2 | surface | Open-Graded HMA Friction Course | 1.5 | 0.75 | Lower structural coefficient; primarily for skid resistance and drainage | 1,380 | 200,000 |
