CONSTRUCTION AND MAINTENANCE OF FLEXIBLE PAVEMENTS. REPORT FROM MEXICO --PIARC XVIII WORLD ROAD CONGRESS, BRUSSELS, BELGIUM, SEPTEMBER 13-19, 1987

Increased gross weights and axle loads of trucks make it necessary to extend the present design method in order to include new information for the construction of stronger, and yet still economical, pavements. A new design criterion is in the development stage, which involves theoretical analysis of existing information and some experimental research, both in the field and in the laboratory. Research is underway on the fatigue and rutting characteristics of bituminous mixes, as well as on improved methods to characterise these materials. Emphasis will be placed on pavement performance in hot climates similar to those which prevail in Mexico. Also studies of the structural behaviour of untreated granular road bases are being carried out. The paper describes the fatigue performance of various full scale pavements, tested in the circular test track of the institute of engineering, unam. Also, information is included on a failure criterion for the characterisation of granular road bases.(a) for the covering abstracts of the congress see IRRD 812115 and 812116.
