BITUMINOUS STABILIZATION OF SANDY SOILS

THE NATIVE MATERIALS IN THE DESERT REGIONS OF INDIA DO NOT LEND THEMSELVES TO ROAD BUILDING. IN ORDER TO AVOID THE EXPENSE OF IMPORTING SUITABLE MATERIALS, THE CENTRAL ROAD RESEARCH INSTITUTE HAS UNDERTAKEN CONTINUING EXPERIMENTS OVER THE PAST NINE YEARS TO FIND WAYS OF STABILIZING THE SANDS FOUND IN THE DESERTS. THE FOLLOWING BROAD CONCLUSIONS CAN BE DRAWN: BITUMINIZED SAND, EITHER WITH OR WITHOUT KANKAR (A SOFT TYPE OF AGGREGATE IN A NODULAR FORM, CONTAINING A HIGH PERCENTAGE OF SILICA AND CALCIUM OXIDE), IS A SUITABLE BUILDING MATERIAL: BECAUSE OF THE ARID CLIMATE WET STABILITY IS NOT A PROBLEM, SAND-ASPHALT, IS SUITABLE THICKNESS, CAN BE USED AS A CUSHION TO PREVENT THE CRUSHING OF KANKAR BASES. FURTHER EXPERIMENTATION SHOULD BE CARRIED OUT IN ORDER TO ESTABLISH FIRMER SPECIFICATIONS FOR THE USE OF BITUMINIZED SANDS. /AUTHOR/
