A TEST OF THE ROAD ALL JOINT HEATER, PRESENTED BY THE AVELING-BARFORD HIRE CO.

THE PROBLEM OF LONGITUDINAL JOINTS ON A ROAD, RESULTING FROM THE DIFFERENT PASSES OF THE FINISHER, IS DISCUSSED. VARIOUS METHODS OF IMPROVING THIS JOINT BY RE-HEATING /WITH PROPANE BURNERS OR INFRARED HEATERS/, ARE STUDIED, AND EVENTUAL CHANGES IN THE BITUMEN AS A RESULT OF THIS RE- HEATING ARE POINTED OUT. TESTS RELATED TO /1/ VARIATIONS IN NEEDLE PENETRATION AND SOFTENING POINT /BALL AND RING/, AND /2/ CHANGES IN THE ADHESION QUALITIES OF THE BITUMEN AS A RESULT OF RE-HEATING WERE MADE. THE TEST METHODS USED AND THE RESULTS OBTAINED ARE GIVEN. IT WAS CONCLUDED THAT THE QUALITY OF THE BITUMEN WAS LITTLE AFFECTED BY THE HEAT APPLICATION, AND THAT IT WAS WORTH PROVING THE EFFICACITY OF THE METHOD BY PERMEABILITY MEASUREMENTS AT THE JOINT, AND BY TENSILE TESTS ON SMALL BARS EXTENDING OUT PERPENDICULARLY FROM THE JOINT. /LCPC/RRL/
