AN INVESTIGATION ON DEGRADATION OF AGGREGATES IN HIGHWAY CONSTRUCTION

THE PAPER REPORTS LABORATORY INVESTIGATIONS AND FIELD EXPERIMENTS TO STUDY THE MECHANICAL AND CHEMICAL DEGRADATION OF DIFFERENT TYPES OF AGGREGATES USED FOR ROAD CONSTRUCTION IN INDIA. THREE TYPES OF AGGREAGTE WERE TESTED; (1) DISINTEGRATED LATERITIC SOIL AGGREGATE (KNOWN AS 'MOORUM') (2) QUARTZ PEBBLES, AND (3) DOLERITE. THE RESULTS OF CRUSHING AND IMPACT LABORATORY DEGRADATION TESTS ARE COMPARED WITH LOS ANGELES ABRASION TESTS, AND PRESENTED IN GRAPHICAL FORM. IT IS CONCLUDED THAT FURTHER RESEARCH IS NEEDED TO CONSIDER THE EFFECT OF CLIMATE, ENVIRONMENT AND TRAFFIC CONDITIONS. /TRRL/
