Mechanical Properties of Asphalt Pavement Sensitivity Analysis Under Overload

By changing asphalt pavement layer modulus under different load conditions,the mechanical properties and pavement performance variation of the surface deflection,surface tensile stress,sub-base tensile stress,subgrade tensile stress are determined with the structure parameters changing of the asphalt pavement under overload.The overloading asphalt pavement should reasonable control the relationship of the layer modulus and increase the subgrade modulus.It provides a theoretical basis for the design and construction of asphalt pavement under overload condition.
