Abstract: The fracture behavior of thin films of bitumen in double cantilever beam (DCB) specimens was investigated over a wide range of temperature and loading rate conditions using finite-element analysis. The model includes a ...

Abstract: A generalized theory for the viscoelastic behavior of idealized bituminous mixtures (asphalts) is presented. The mathematical model incorporates strain rate and temperature dependency as well as nonmonotonic loading and ...

Abstract: Experimental data for pure bitumens and simplified theoretical models for their deformation behavior are assembled into a single framework that summarizes their steady-state inelastic response to stress. A number of regimes ...

Abstract: This paper contains details of uniaxial compression experiments on various idealized asphalt mixes with volume fractions of aggregate ranging from 40 to 85%. The compression experiments are performed over a wide range of ...

Abstract: A micromechanical model for the steady-state deformation of idealized asphalt mixes is presented. Triaxial compression tests were conducted on idealized asphalt mixes and the volumetric and deviatoric strains were measured. ...

Abstract: Two new models are described for a composite consisting of a nonlinear viscous matrix reinforced by rigid particulate inclusions: (1) An analytical plane strain solution for a uniform regular array of rigid hexagonal ...

Abstract: The behavior of power-law creeping materials in the form of thin films subject to plane strain and axisymmetric deformation is studied. Analytical calculations, finite-element analysis, and experimental studies are performed. ...

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: This paper investigates the adhesive properties of bitumen films. Tensile tests on bitumen butt joints and double cantilever beam specimens, over a wide range of test conditions, are described. The test results are treated ...
