Lacunar-Stroke

Some Strengths and Weaknesses of Overstress Based Elastic Viscoplastic Models,resents the theoretical formulation of this type of models and highlights the abilities and shortcomings of such models to reproduce the time dependent behaviour of clays observed in the laboratory and the implications that these have when used in the analysis of boundary value problems.

Comparison of Anisotropic Rate-Dependent Models at Element Level,els are identical in the way the evolution of anisotropy is simulated, but differ the in way the rate-effects are taken into account. Based on numerical simulations against element level tests, using objective parameters, suggest that EVP-SCLAY1 is able to give a better representation of the clay re

A Comparison of Four Elastic Visco-Plastic Models for Soft Clay,o describe the soil behaviour. For applied loadings that increase the stresses to around the in-situ yield stress, the predicted behaviour is strongly influenced by the associated breakdown of clay structure and the way in which this is modelled. Four elastic visco-plastic models have been compared

Influence of Recycled Asphalt Pavement on Creep Compliance of Hot Mix Asphalt, (Oklahoma S3) with a nominal maximum size (NMS) of 19 mm. A total of two mixes, one containing 25% RAP and the other containing 40% RAP, were designed and tested for creep compliance. It was found that at lower temperature, the mix containing 25% RAP content is stiffer, as indicated by higher creep

Simplified Modelling of Isotache Concept for Consolidation,on pressure and the strain rate. The former and the latter can be obtained from one constant rate of strain consolidation test (CRS test) and one long-term consolidation test (LT test), respectively. The latter is expressed by an equation with three isotache parameters initially determined for Osaka
