Abstract: A new whole-life pavement-performance model (WLPPM) that is capable of making deterministic pavement-damage predictions due to realistic traffic and environmental loading has been developed. A vehicle simulation is used ...

Abstract: A new asphalt layer modulus degradation model for use with flexible-pavement analysis procedures is described. The model is capable of determining the reduction in stiffness of the asphaltic material in a flexible pavement ...

Abstract: The spherical indentation response of a dense bitumen macadam asphalt mixture with two different volume fractions of bitumen binder is investigated both experimentally and via an analytical model. The model for the indentation ...

Abstract: This paper describes results from a laboratory investigation into the effects of the interaction between a styrene-butadiene-styrene (SBS) modified bitumen and recycled crumb rubber on the mechanical performance of impact ...

Abstract: Permanent deformation (rutting) in bituminous pavements is treated as a linear viscoelastic flow phenomenon and is calculated using the linear elastic layered pavement model VESYS, reported by Kenis in 1978, supplied with ...

Abstract: The saturation aging tensile stiffness (SATS) test has been developed to quantify the moisture damage of a range of U.K. asphalt mixtures. In order to combine the effects of moisture and aging, the test is undertaken at ...
