Abstract
Finite element method is employed to analyse tensile stress at the bottom of asphalt concrete layer and semi-rigid base, tension strain, road surface deflection and shear stress in asphalt concrete layer. The influence of graded macadam bases modulus on mechanical properties is studied. Meanwhile considering field modulus test values, reasonable value of graded macadam bases modulus, which is suitable for each road grade and each layer position, is proposed.
