Expansive soils are problematic due to the performances of their clay mineral constituent,
which makes them exhibit the shrink-swell characteristics. The shrink-swell behaviours …

Expansive clay soils—those that change significantly in volume with changes in water
content—are the cause of distortions to structures that cost taxpayers several billion dollars …

Unsaturated soil mechanics has rapidly become a part of geotechnical engineering practice
as a result of solutions that have emerged to a number of key problems (or challenges). The …

This PhD thesis is composed of a synopsis and five published papers that are focused on
both the research results of studies on electrical properties of road materials and subgrade …

This study uses climate projections from multiple models and for different climate regions to
investigate how climate change may impact the transportation infrastructure in the United …

This paper presents, by way of comparison, the effect of fly ash on the volume change of two
different types of clay, one a highly plastic expansive clay and the other a nonexpansive …

The influence of the stress regime change and associated softening can be significant on
unsaturated expansive soil slope stability due to soil swelling upon wetting, which cannot be …

A new method is proposed to estimate the vertical movement of the ground surface for soil
that swells and shrinks due to variations in water content. The water content is used as the …

This paper describes key research on expansive soils and the methods employed to
characterize them; fallacies in the current characterization of expansive soils are also …

The prediction of heave in unsaturated, expansive soils has historically been studied
primarily as a one-dimensional type analysis. This paper proposes a methodology that can …
