| Abstract: | On the basis of the non-linear(elasticity and plasticity) property of granular base, variation rules for maximum flexural tensile stress of surface course underside and semi-rigid base underside are studied with non-linear finite element solution for three types of pavements of a test road in Tonghua City of Jilin Province. Some reasonable suggestions are brought forward to semi-rigid asphalt concrete pavement with granular base in the test road. Fatigue lives of surfacing course of two types of semi-rigid asphalt concrete pavement with granular base are forcasted. |
