PERFORMANCE OF ASPHALT PAVEMENTS SUBJECTED TO DE-ICING SALTS

THIS PAPER DESCRIBES A LABORATORY INVESTIGATION ON THE PERFORMANCE OF ASPHALT PAVEMENT SUBJECTED TO THE COMMON DEICING SALTS. VARIOUS TESTS WERE MADE ON THE SPECIMENS IMMEDIATELY AFTER THEY WERE PREPARED AND AFTER 10, 50 AND 100 DAILY TEST CYCLES. COMPARISONS OF THE TEST RESULTS INDICATED THAT THE REPETITIVE DAILY APPLICATIONS OF THE DE-ICING SALTS TO MELT ICE FROM THE SURFACES OF SPECIMENS HAD NO SIGNIFICANT EFFECTS ON SPECIMEN STABILITIES, OR ON THE PENETRATION, SOFTENING POINT, OR DUCTILITY OF ASPHALT RECOVERED FROM THE SPECIMENS. NO LOSS OF AGGREGATE FROM ANY SPECIMENS OCCURRED DURING THE TESTS. NO DETRIMENTAL EFFECTS OF THE DE-ICING SALTS ON THE ASPHALT PAVEMENT SPECIMENS SUBJECTED TO THE TESTING CONDITIONS USED FOR THE INVESTIGATION WERE INDICATED BY THE TEST RESULTS. THE STUDY OFFERS EVIDENCE THAT WELL-DESIGNED AND WELL-CONSTRUCTED ASPHALT PAVEMENTS ARE NOT DAMAGED BY SODIUM AND CALCIUM CHLORIDE SALTS USED FOR ICE AND SNOW CONTROL. /AUTHOR/
