THE DEFORMATION AND FRACTURE BEHAVIOR OF THE BINDER IN BITUMINOUS ROAD SURFACING MATERIALS UNDER TRAFFIC LOADING

THE DEFORMATION AND FRACTURE BEHAVIOR OF THE THIN FILMS OF BINDER IN BITUMINOUS ROAD SURFACING MATERIALS IS DESCRIBED PARTICULARLY WHEN THEY ARE SUBJECTED TO HIGH RATES OF LOADING SUCH AS THOSE PRODUCED BY TRAFFIC MOVING OVER THE PAVEMENT. THE BEHAVIOR DEPENDS NOT ONLY ON THE RESPONSE OF THE FILMS TO SHEAR FORCES (TANGENTIAL TO THE PLANE OF THE FILM) BUT ALSO ON THE MODIFICATION OF THIS RESPONSE WHEN THE FILMS ARE SUBJECTED TO TENSION OR COMPRESSION FORCES (FORCE DIRECTION NORMAL TO THE PLANE OF THE FILM). THE LOCATIONS WHERE FILMS ARE IN TENSION/COMPRESSION PROVIDE THE MATERIALS WITH RESISTANCE TO DEFORMATION UNDER HOT PAVEMENT CONDITIONS BUT ALSO PRODUCE THE STRESS CONCENTRATION SITES FOR FATIGUE FAILURE AT LOWER PAVEMENT TEMPERATURES. THE IMPLICATIONS OF THIS IN RELATION TO THE SERVICE PERFORMANCE OF SURFACINGS AND THE DESIGN OF DENSE HOT MIX IS DISCUSSED. /ARRB/
