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.

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 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

Rutting progression models for light duty pavements

International Journal of Pavement Engineering, 2016
AbstractDeterioration models allow road managers to assess current condition and to predict future conditions of their road networks. Due to heavy vehicle axle repetitions and the effect of environmental factors, permanent deformation (rutting) develops gradually in the wheel paths and impacts on structural and surface performance of flexible pavements.

Modeling Asphalt Pavement Rutting under Accelerated Testing

Road Materials and Pavement Design, 2008
ABSTRACT This paper presented a developed mechanistic-empirical (ME) model for simulating the rutting depth of asphalt pavements under the accelerated testing. This model is based on the power law of vertical strain, and it empirically correlates the layer rutting depth to the cyclic deflection.

Asphalt concrete rutting predicted using the PEDRO model

International Journal of Pavement Engineering, 2014
This paper presents a theoretical viscoelastic approach, called PEDRO (PErmanent Deformation of asphalt concrete layers for ROads), for predicting rut formation in asphalt concrete materials subjected to traffic loading. Input data are traffic parameters, asphalt concrete viscosity and asphalt layer thickness. Vertical strains that cause rutting in the

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 ...

Empirical Rutting Models of Recycled Mixtures Containing CRM

Pavement Mechanics and Performance, 2006
Recycling of Reclaimed Asphalt Pavement (RAP) is now a normal practice because it saves aggregate resources and reduces environmental pollutants. The performance properties of asphalt mixture containing RAP could be improved by adding additives such as crumb rubber modifier (CRM).

Predicting a Model for Modified Asphalt Cement Rutting Parameters

Key Engineering Materials, 2021
This paper aims to investigate the relationship between the Superpave rutting parameter of asphalt (G﹡/sin δ) by conducting Dynamic Shear Rheometer (DSR) tests with the rut depth values obtained by the wheel track device. The twenty asphalt mixtures have been prepared with twenty types of unmodified asphalts and Polymer-Modified Binders (PMBs). SBS was
