Abstract: This paper presents a method to characterize the fabric of soils. Attention is focused on the directional distribution of voids in these materials. The mean porosity and void fabric tensor used in the description are ...

Abstract: The development and implementation of a constitutive model used to predict the behavior of unsaturated sands are described. The model is based on critical state and bounding surface concepts and incorporates parameters to ...

Abstract: This paper presents a state-dependent constitutive model for sand formulated within the critical-state framework and its implementation into a numerical analysis (FLAC3D) program. The implemented model was verified by using ...

Abstract: The general availability of computers has provided efficient means of assessing the stability of slopes using several analytical methods. However, the increased use of computers coupled with a lack of unified presentation ...

Abstract: The performance of asphalt concrete (AC) mixtures is influenced by the arrangement of aggregates and their associated air voids. Parameters to measure aggregate orientation, aggregate gradation, and air void distribution ...
