Abstract

Fundamental differences exist in soil types formed under temperate and tropical climatic conditions. Consequently, their use for road pavement design will require different approaches and standards. The absence of a systematic approach in addressing tropical pavement design requirements and the use of temperate design standards for tropical countries has led to early failure of road pavements in Ghana and other tropical countries. However, few studies have been carried out on developing standards based on field studies to determine key design parameters to address challenges of tropical pavement design.

The aim of this research is to evolve a rational approach using mechanistic-empirical principles to design pavements for tropical laterite soils. The main objectives were therefore to determine the key pavement design parameters for Ghana through empirical studies as well as carry out technical and economic analysis to establish optimum designs for the various climatic zones of Ghana.
