Abstract: Fatigue performance of asphalt mixture is one of the most important of asphalt pavement with flexible base. On the basis of the application experience of west district of China, flexible asphalt pavement structure’s ...

Abstract: The cracking resistance of a high modulus asphalt mixture (HMAM) containing reclaimed asphalt pavement (RAP) was studied in this paper. Asphalt binder #30 and a high modulus additive were used to prepare HMAM containing ...

Abstract: An algorithm for generating three-dimensional aggregates was developed first in this study. This algorithm can model the various shapes, sizes, and angularity of coarse aggregates. The shapes, sizes, and angularity of the ...

Abstract: This paper proposes a new modeling method to reconstruct hollow shapes of aggregate particles using the discrete-element method (DEM) to accurately characterize the microstructures of aggregates and efficiently predict the ...

Abstract: Recently, a shape memory polymer-based self-healing syntactic foam was proposed and tested as a sealant for expansion joints. The key for success is to train the foam by using a two-dimensional (2D) stress condition ...

Abstract: It has been observed that permanent deformation (or rut) in the asphalt pavement at an intersection is much more severe than a deformation away from the intersection due to breaking horizontal forces and longer loading ...

Abstract: Based on mixture mass change in water and scattering loss in alternate freeze-thaw process, anti-freezing capability of mixture is discussed, with the mechanism of asphalt mixture mass change and strength reducing analyzed ...

Abstract: In order to comparing the stress situations of asphalt overlay on the rubblized or non rubblized slab. Based on eight-node isoparametric element, the stress intensity factor of asphalt overlay on the two different base ...
