Review of Specifications for the Use of Laterite in Road Pavements

Abstract

The main purpose of this report is to: Raise awareness of the existence of the performance-based specifications that have been developed specifically for the use of laterites in road construction in such countries as Angola, Brazil and Australia. Highlight the fact that such specifications are quite different to the more traditional ones that are still used in a number of countries in Africa, as a result of which unnecessary recourse is often made to the relatively expensive stabilization of these local materials for use in low volume roads (LVRs). Review existing specifications for the use of laterites in LVR construction based on the most recent/relevant documentation on the subject
