CRACKING OF ASPHALT PAVEMENTS DUE TO THERMAL CONTRACTION

CRACKING OF ASPHALT PAVEMENTS MAY BE A DETRIMENT TO PAVEMENT PERFORMANCE BECAUSE OF THE INFILTRATION OF SURFACE MOISTURE INTO THE UNDERLYING MATERIALS THROUGH IMPROPERLY SEALED CRACKS. ONE OF THE CAUSES OF SUCH CRACKING IS THE STRESS SET UP IN THE SURFACE COURSE BY THERMAL CONTRACTION. IN THIS PAPER THE AUTHORS ATTEMPT TO ANALYZE THE CONDITIONS UNDER WHICH THERMAL CRACKING IS MOST LIKELY TO OCCUR. THE RESULTS OF THE LABORATORY STUDY AND PAVEMENT CRACK SURVEY INDICATE THAT ASPHALTIC CONCRETE MAY CRACK DUE TO THERMAL CONTRACTION UNDER EITHER OF THE FOLLOWING TWO CONDITIONS' FIRST, A PROLONGED PERIOD OF AIR TEMPERATURES IN THE ORDER OF MINUS 4 DEGREES F, AND SECOND, DEPRESSING TEMPERATURES BEYOND MINUM 4 DEGREES F FOLLOWED BY SUDDEN ELEVATED TEMPERATURES ABOVE 4 DEGREES F. THE FORMAL DISCUSSION ACCOMPANYING THE PAPER SHOW THAT A NUMBER OF OTHER FACTORS ARE RELEVANT TO THE ASPHALT PAVEMENT CRACKING PROBLEM. THESE FACTORS MAY INCLUDE THE CHARACTERISTICS OF THE SUBGRADE SOIL AND BASE COURSE AND THE PROPERTIES OF THE ASPHALT CEMENT AND SURFACING MIXTURE. /CGRA/
