This paper proposes a new multi-surface plasticity model for the cyclic hardening of
unsaturated granular soils crucial for assessing their resilience jointly under repeated …

The contamination of ballast by mud pumping is known to cause considerable reduction in
the shear resistance as well as increased settlement of railroad foundations. However, how …

The water retention properties of soils present in formation layers of roads and railways
continuously vary due to repeated traffic loads and periodic rainfall events. This is important …

This paper presents the results of laboratory testing of a clayey soil taken from a road
subgrade in Tanzania. The results revealed a reduction in the soil water retention capacity …

Understanding the behaviour of compacted soils in road and railroad formations is crucial
for ensuring the long-term performance of transportation infrastructure. These formations are …

Unsaturated soils often form part of geo-infrastructure such as road and railway
substructures subjected to repeated traffic and train-induced loading. However, the …

The characterization of soil-water retention curves is a necessity for the modelling of
earthworks response to long-term changes in seasonal changes in precipitation, as well as …
