Finite Element Simulation Model of Asphalt Pavement Based on ABAQUS

Abstract: The seepage damage mechanism is explained, and the finite element simulation software ABAQUS is introduced in the paper. The seepage field and stress field 3D finite element numerical model of asphalt pavement are established by using the nonlinear dynamic analyzing ability of ABAQUS. The occurrence and changing regularity of the pore water pressure, vertical displacement and 3D stress are explored. Then the test on simulate road of one highway is made to prove the theory results. The examples indicate that the simulation of seepage field under rainfall condition and stress field under moving vehicle loads through ABAQUS software is practicable with satisfactory results.#br# Key words: finite element simulation; asphalt pavement; seepage field; stress field; ABAQUS
