Abstract: Since the linear elastic layer solution for the layered systems was developed in the 1940s, the linear elastic layer analysis has been systemized and widely used for the designs of roadway pavements as a tool for evaluating ...

Abstract: Fatigue cracking is a major problem in asphalt pavement. It would be beneficial for predictions of the fatigue life of asphalt mixtures to be made with minimal effort and time, both at the design stage and the operating ...

Abstract: The fracturing of materials is well known on the basis of the theory of fracture mechanics. An important concept in fracture mechanics theory is that crack propagation is governed by the fundamental material properties of ...

Abstract: The indirect tension test has received extensive attention due to its capability to test field cores from thin asphalt layers. For that reason, the fundamental viscoelastic material property, creep compliance, or complex ...

Abstract: The viscoelastic continuum damage model, developed based on Schapery’s correspondence principle and the continuum damage mechanics, has received a great deal of attention because of its mathematical soundness and effectiveness ...

Abstract: An excessive amount of differential settlement was observed during the construction of taxiways at Changi Airport in Singapore. The pavement exhibited severe settlement (up to 200 mm). The first cracks appeared in ...

Abstract: Creep compliance (or relaxation modulus), which is a fundamental property that determines the strain (or stress) development in flexible pavements or damage evolution in asphalt mixtures, can be determined from either a ...

Abstract: When employing linear elastic layer analysis, which is widely used for the structural analysis of flexible pavements, it is commonly observed that most critical tensile strains occur at the bottom of an asphalt layer. It ...

Abstract: Because of its efficiency in analyzing complex viscoelastic problems, the finite-element (FE) analysis has been widely used to identify the time- and rate-dependent effects of viscoelastic materials on various structural ...
