PEEL STRENGTH BEHAVIOR OF VARIOUS ASPHALT-STONE ADHESIVE JOINTS

THE EFFECTS OF METHODS OF JOINT FORMATION, TYPE OF STONE /AGGREGATE/, TYPE OF ASPHALT, AND TEST TEMPERATURES ON ASPHALT-STONE /AGGREGATE/ ADHESION WERE MEASURED BY A PEEL TEST APPLIED TO ADHESIVE JOINT SPECIMENS IN THE FORM OF STONE-ASPHALT-ALUMINUM FOIL SANDWICHES. THE RESEARCHERS CONCLUDED' /1/ EXPOSURE TESTS CONCERNED WITH THE EFFECTS OF WATER ON ASPHALT-STONE ADHESIVE JOINTS REVEAL NO HARMFUL EFFECTS ON JOINT STRENGTH, /2/ AT 140 DEGREES F, PEEL TESTS OF JOINTS FORMED IN AIR SHOW HIGHER PEELING RATES THAN AT 77 DEGREES F AND THE JOINTS FAIL COHESIVELY WITH A MORE SYMMETRICAL RESIDUAL DISTRIBUTION OF ADHESIVE, /3/ AT 77 DEGREES F, PEEL TESTS OF JOINTS FORMED UNDER WATER WITH NO CLAMPED PERIOD REVEAL A LACK OF ADHESION REGARDLESS OF THE TYPE OF STONE OR ASPHALT USED. JOINTS FORMED UNDER THE SAME CONDITION BUT TESTED AT 140 DEGREES F SHOW SOME ADHESION BUT NOT TO THE EXTENT OBSERVED FOR SIMILAR JOINTS FORMED IN AIR, AND /4/ JOINTS FORMED AND CLAMPED UNDER WATER FOR SIXTEEN HOURS INDICATE THAT THE CONTACT INTERVAL IS NOT SUFFICIENT FOR GOOD ADHESION, WHEN TESTED AT 77 DEGREES F AND 140 DEGREES F. /BPR/
