Analysis on Mechanical Response for Asphalt Pavement Based on Thickness Variation for Transition Layer of Graded Crushed Rock

Abstract:

The graded crushed rock layers is set between asphalt surface course and semi-rigidity base course to effectively prevent or reduce the reflection crack of semi-rigidity base course and improve the draining condition of asphalt pavement, however, the graded crushed rock is low in modulus and is provided with nonlinearity stress-strain characteristic, and the addition of this transition layer may cause the stress variation of pavement structure. Through applying KENPAVE pavement design program, analyze the mechanical response discipline on pavement structure layer by thickness variation of graded crushed rock layer and put forward the reasonable suggestions for structural design of asphalt pavement for transition layer of graded crushed rock.
