Abstract: The linearity limits of various unmodified and modified bituminous binders, as well as asphalt mixtures incorporating these binders, have been investigated using a dynamic shear rheometer and a purpose-built, dynamic, ...

Abstract: This note outlines the experimental investigation of the factors affecting bond development between pavement layers. The tests involved the use of an apparatus known as the Nottingham shear box. To establish a realistic ...

Abstract: Discrete element modeling has been used to simulate constant strain rate compressive tests for an idealized asphalt mixture comprising approximately single-sized sand particles. A range of constant strain-rate compressive ...

Abstract: In the 1970s, the U.K. Transport Research Laboratory published a series of reports dealing with wearing course slippage due to debonding. At present, however, no accepted nondestructive test (NDT) technique exists for a ...

Abstract: This paper describes research carried out to investigate pavement material-stiffness modulus variability. Detailed pavement surface deflection data were obtained from two sections of newly constructed flexible pavement in ...

Abstract: This paper summarizes a theoretical study undertaken to provide a deeper understanding of the consequences of poor bond on flexible pavement performance. Two different modeling approaches have been used. In the first, the ...
