Review of some Geotechnical Aspects on Structural Response of Rigid Pavements

Abstract

A highway pavement consists of stacked layers of processed materials over a natural soil subgrade to distribute traffic loads. The pavement should have a suitable riding surface, skid resistance, light reflectivity, and little noise pollution. The purpose is to reduce wheel-load transmitted stresses, so they don't exceed subgrade bearing capacity. Flexible and rigid pavements are employed. This paper identifies and summarizes papers by studies on rigid pavement response and performance. It will also explain subgrade soil and its improvement, rigid pavement analysis and design by various approaches, and the appropriate plan and response reduction (stresses, strains, and deflection) to avoid early pavement failure due to traffic loads.
