TENSILE STRENGTH OF ASPHALT FILMS AND ROAD LIFE

THE TENSILE STRENGTH OF THIN FILMS OF 12 ASPHALTS IN DIFFERENT CONDITIONS OF AGING-UNAGED, AGED IN THE THIN FILM OVEN TEST, AND AGED IN ROADS FOR UP TO ELEVEN YEARS- INCREASED BY AS MUCH AS 140 PERCENT AS THE TEMPERATURE DECREASED FROM 80 TO 0 F. EXPERIMENTAL CONDITIONS INSURED FAILURE BY BRITTLE FRACTURE. AT LOW TEMPERATURES, (TFOT) AGING PRODUCED NO SIGNIFICANT DIFFERENCES IN THE TENSILE STRENGTH OF THE ASPHALTS BUT ROAD AGING PRODUCED LARGE DIFFERENCES. THE TENSILE STRENGTH OF ROAD-AGED ASPHALTS APPEARS UNRELATED TO ASPHALT SOURCE OR COMPOSITION. /AUTHOR/
