Abstract: The mechanical performance of pavement systems depends on the stiffness of subsurface soil and aggregate materials. The moduli of base course, subbase, and subgrade soils included in pavement systems need to be characterized ...

Abstract: Despite clear evidence, changes in mechanical properties (i.e., stiffness or modulus) of compacted subgrades in response to subgrade moisture regime changes after construction have rarely been investigated in the geotechnical ...

Abstract: This paper describes a study of the physical effects of exposing three geosynthetics commonly used in waste containment systems (a geomembrane, geotextile, and drainage geocomposite) to a synthetic acidic mine drainage ...
