HIGH TYPE BITUMINOUS MIX DESIGN FOR A ROAD AND AN AIRFIELD PAVEMENT, WITH RIVER SHINGLES (GRAVELS)

This article gives an account of work that has been carried out with the object of obtaining a suitable design for asphaltic concrete for road and airfield pavements using river gravels from various parts of n.e. India. The author outlines other studies of gravel aggregate in asphaltic concrete that have been made in America and india and gives an account of his own work, which involved the laboratory testing of the materials used, the design of mixes and their subsequent testing. It is concluded that suitable mix designs could be obtained, and that whilst small changes in the grading of the gravel had little affect on the marshall stability characteristics of road asphalt, airfield asphalt was more sensitive to grading, because of the increased compacting effort. It is also concluded that whilst strict adherence to grading requirements is important, it is unnecessary to aim at special mix proportions; i.e. That it is only necessary to specify ultimate design criteria and so allow the aggregates available at a site to be used in A suitable mix design. /TRRL/
