The graded aggregate transition layer can effectively prevent or reduce reflective cracks in the semi-rigid base
course and improve the drainage conditions of asphalt road surface, but, graded aggregate has a low modulus and a nonlinear
stress-strain behavior. If such graded aggregate is used as a transition layer between the asphalt surface layer and the semi-rigid
base，it may change the stress of original pavement structure. By using pavement design software based on the nonlinear theory,
surface deflection, tensile stress in underside of surface layer and semi-rigid base course, compressive strain on top of subgrade
and other control indicators are analyzed from two structural parameters of thickness and modulus of asphalt surface layer. The
law of mechanical response of the variation of thickness and modulus of resilience of asphalt pavement on the tensile,
compressive and shear stress in various structural layers of road pavement is analyzed and summarized, providing important
reference for the combined design of inverted pavement structures.
