Model Prediction of Rutting in Asphalt Concrete

Journal of Transportation Engineering, 1998
A new elastoplastic model is presented for predicting the stress-strain response of asphalt concrete under cyclic loading. The model utilizes multiyield surfaces and isotropic hardening. Rowe's stress dilatancy theory is used to obtain the relationship between the permanent volumetric and vertical strains as well as the hardening law for the changes in

Modeling wheel-induced rutting in soils: Indentation

Journal of Terramechanics, 2008
The analysis of indentation of rigid cylindrical wheels into frictional/cohesive soils is presented. Three- and two-dimensional numerical simulations were performed using the finite element code ABAQUS to assess the influence of soil strength parameters, dilatancy, and wheel geometry on the relationship between the indentation force and wheel sinkage ...

Model for forecasting ruts in rutting tester

Sixth International RILEM Symposium on Performance Testing and Evaluation of Bituminous Materials, 2003
The results of research on the rheological parameters of mineral-asphalt mixes subjected to the creep test in the Nottingham Asphalt Tester (NAT) are presented. The rheological parameters were determined through the approximation of the experimental creep curves by the theoretical curves for three viscoelastic models: the Maxwell model, the Burgers ...

Modeling wheel-induced rutting in soils: Rolling

Journal of Terramechanics, 2009
Theoretical models for predicting penetration of non-driving (towed) rigid cylindrical wheels rolling on frictional/cohesive soils are presented. The models allow for investigating the influence of soil parameters and wheel geometry on the relationship between the inclined rolling force and wheel sinkage in the presence of permanently formed ruts.
