Addressing Transportation Geotechnics Challenges Using Mechanics of Unsaturated Soils
Abstract Cost-effective and high-quality transportation systems are critical to the regional, national as well as international development. The design and maintenance of the pavements, which form a critical component of the transportation systems, should address the geotechnics challenges that arise from the influence of external environment, which include the seasonal drying–wetting and freeze–thaw cycles. Environmental factors influence on the pavements can contribute to their deterioration or even failure in certain scenarios. This paper presents recent advancements in the mechanics of unsaturated soils that can be used in the reliable mechanistic pavement design methods. Simple yet reliable approaches that have been developed for predicting the soil–water characteristic curve (SWCC) and the variation of the resilient modulus (MR) with moisture content and suction are introduced and integrated. The proposed integrated approaches provide reliable predictions of the SWCC and the MR using limited experimental data that can be determined from conventional geotechnical tests, and can be used in the rational pavement design practice.
