ADHESION TESTS FOR BITUMINOUS MATERIALS

A SERIES OF AGGREGATES OF KNOWN ROAD PERFORMANCE WITH 300- PEN. BITUMEN IN BITUMEN-MACADAM WEARING-COURSES HAS BEEN EXAMINED BY FIVE DIFFERENT, KNOWN ADHESION /STRIPPING/ TESTS THE RESULTS OF THE STATE IMMERSION AND MALLISON TESTS SHOWED NO SATISFACTORY CORRELATION WITH EACH OTHER, WITH THE RESULT OF OTHER TESTS OR WITH PRACTICAL PERFORMANCE. THE OTHER THREE TESTS GAVE MORE SATISFACTORY RESULTS WHICH BORE SOME RELATION TO EACH OTHER AND TO PRACTICAL PERFORMANCE. THE IMMERSION WHEEL-TRACKING TEST GAVE THE BEST GENERAL RELATION TO PRACTICAL PERFORMANCE PROVIDED THAT THE EFFECTS OF STABILITY OF PARTIALLY STRIPPED MATERIALS WERE TAKEN INTO ACCOUNT AS WELL AS THE AMOUNT OF STRIPPING. THE RIEDEL & WEBER AND IMMERSION COMPRESSION TESTS GAVE GOOD CORRELATION WITH ROAD PERFORMANCE FOR MIXTURES NOT SHOWING STRIPPING IN PRACTICE AND ALSO DETECTED THOSE MIXTURES WHICH STRIPPED READILY ON THE ROAD. WITH AGGREGATES OF INTERMEDIATE ROAD PERFORMANCE, THE TEST RESULTS WERE LESS SATISFACTORY. THERE IS REASON TO SUSPECT THE VALIDITY OF BOTH OF THESE TESTS WHEN ADHESION AGENTS ARE PRESENT IN THE BINDER.
