Numerical Method of Flexible Pavement considering Moisture and Stress Sensitivity of Subgrade Soils
Weaknesses of the subgrade structure induce the asphalt surface diseases and shorten the service life of flexible pavement. However, the resilient modulus (Mr) of subgrade soils is difficult to be evaluated directly since the subgrade is hidden and ...
