Comparison of Stochastic Responses of Asphaltic Concrete ...

2016-11-7  This paper presents the advantages of using asphalt in lining dams and in asphaltic concrete core dams when comparing with clay core dams. For this purpose, the linear and nonlinear stochastic responses of a clay core dam, an asphaltic lining dam and an asphaltic concrete core dam subjected to stationary and non-stationary excitation including spatially varying ground motion (SVEGM) effects ...

Modulus of Asphalt Mixtures­ An Unresolved Dilemma

dependent responses such as creep and relaxation are typical of viscoelastic materials. The responses of asphaltic mixes are time and temperature dependent and consequently they should be analyzed as such. Under some special conditions, however, this behavior can be approximately considered as elastic, and reasonable solutions

In this work, a micro-crack informed stochastic damage analysis is performed to consider the failures of material with stochastic microstructure. The derivation of the damage evolution law is based on the Helmholtz free energy equivalence between cracked microstructure and homogenized continuum. The damage model is constructed under the stochastic representative volume element (SRVE) framework.
