Highway materials and design for the middle eastern environment

In the middle east the main form of road pavement distress is rutting. When cracks occur they usually start at the top of the wearing course; the form of fatigue failure normally considered in pavement designs, ie, cracking initiated at the bottom of the pavement, is seldom if ever seen. The paper discusses some of the problems that have been encountered in trying to apply British and American designs and materials in the middle east. They are inefficient, because the designs do not fully utilise the region's strong subgrades, and inadequate, because the material cannot withstand the very high temperatures and wheel loads that are experienced. Some successful adaptations are described including the development of a new method for designing deformation resistant wearing courses and the use of latex modified asphaltic cements. Finally the paper describes an instrumented full scale experiment under way in dubai, intended to permit the development of materials and pavement designs appropriate to such environments (a).
