Unsaturated soil is a form of natural soil whose pores are filled by air and water. Different
from saturated soil, the microstructure of unsaturated soil consists of three phases, namely …

In this paper, equations that were proposed in the literature over the past four decades to
estimate or predict the variation of the resilient modulus with respect to soil suction for …

The resilient modulus of the materials used in various pavement layers has been used
extensively as an important material property in structural design of pavement. The state of …

Considering the great contribution of subgrade modulus to the overall performance of roads
or railways, it is crucial to provide the best prediction of resilient modulus for their …

Soil suction (ψ) is one of the key factors that influence the resilient modulus (MR) of
pavement subgrade soils. There are several models available in the literature for predicting …

The resilient modulus (MR) is essential for the understanding of pavement response to
climate effects, and to seasonal fluctuations of water content and matric suction …

At first glance, roads seem like the simplest possible geotechnical structures. However,
analysis of these structures runs up against complexities related to the intense stresses …

South Africa is cut-across an arid and semi-arid zone, this implies that 95% of its roadbed is
under unsaturated condition. In this context, resilient performance of subgrades is …

This paper examines the performance of unsaturated soils under repeated loading. As part
of the research, a triaxial system was developed that incorporates small-strain …

The assessment of the structural performance of inundated pavements is crucial to reduce
the induced damage in the aftermath of flooding. The objective of this study is to present a …
