Rutting Resistance Ability Analysis of Heavy Duty Asphalt Pavements Based on Consecutive Temperature Variation and Finite Element Method

摘要

Based on the Bailey-Norton elastic-plastic constitutive model to the asphalt mixture, Mohr-Coulomb plastic constitutive model to the unbounded granular material, and the ABAQUS finite element platform, resistance ability to rutting of 4 typical pavements are studied. Results reveal that: the existence of unbounded granular material between asphalt layer and cement treated material appears negative effect to rutting resistance ability; factors such as temperature, tire-road contact pressure, traffic volume, modulus and thickness of asphalt layers have significant effects on asphalt pavement rutting resistance; rutting prediction models which can be used in new construction design are obtained by regression from orthogonal experiment design.
