BEHAVIOR OF BITUMINOUS ROAD MATERIALS UNDER REPETITIVE LOADING

ROADS FAIL AFTER THE APPLICATION OF LARGE NUMBERS OF WHEEL LOADS RATHER THAN AFTER A SINGLE APPLICATION. A POSSIBLE MECHANISM OF FAILURE IS THE WEAKENING OF THE BOUND LAYERS BY A PROCESS OF FATIGUE, ENGENDERED BY THE REPEATED FLEXURE OF THE PAVEMENT CONSTRUCTION. THIS PAPER, WHICH IS CONCERNED SOLELY WITH FLEXIBLE ROADS, REVIEWS BRIEFLY THE SCOPE OF SOME PREVIOUS INVESTIGATIONS OF THE FATIGUE PROPERTIES OF BITUMEN BOUND MATERIALS, AND THEN SUMMARIZES THE PRESENT STATE OF KNOWLEDGE IN THIS FIELD. FINALLY A PROGRAM OF RESEARCH CURRENTLY BEING CARRIED OUT JOINTLY BY THE REFINED BITUMEN ASSOCIATION LTD., AND THE ROAD RESEARCH LABORATORY IS DESCRIBED. /RRL/A/
