Conference on highway engineering in Africa Addis Ababa April 1974: Synopses of papers
This paper summarizes methods that have been used to design and construct road pavements in Africa. It draws heavily on the experience of British and French engineers who have observed the behavior of large lengths of roads in many African countries.This paper describes the use of deflection techniques for evaluating the condition of existing flexible roads and determining the most economical method of strengthening. The role of deflection criteria in the strengthening design process is considered and a deflection survey and analysis procedure using hand deflection beams is outlined. Particular attention is given to the design of overlays for soil-cement roads and roads on expansive clay's.
