Study on Evaluating the Influence of Mechanical Parameters to Semi-Rigid Base of Asphalt Pavement in Service

摘要

In order to study the subgrade structure situation of existing asphalt pavement, unconfined compressive strength, and the resilience modulus with single axis compression were adopted to evaluate semi-rigid asphalt base in service. The mechanical parameters could be used to analysis the mechanism of transverse cracks, which would provide necessary technical support for maintenance.
