LABORATORY STUDY OF ASPHALT PAVING MIXTURES

THIS PAPER SUMMARIZES THE RESULTS OF A PORTION OF AN EXTENSIVE LABORATORY TEST PROGRAM WHICH STUDIED BASIC FACTORS AFFECTING THE QUALITY OF ASPHALT PAVING MIXTURES. THE FACTORS STUDIED WERE: (A) AMOUNT OF ASPHALT CEMENT, (B) AGGREGATE GRADATION, (C) AGGREGATE TYPE, (D) FILLER, AND (E) PENETRATION GRADE OF ASPHALT CEMENT. SINCE THE TECHNIQUE FOR SAMPLE PREPARATION WAS THE SAME FOR ALL TESTS, THE FACTOR OF DENSITY PRODUCED BY DIFFERENT COMPACTIVE EFFORTS WAS NOT A CONSIDERATION. SINCE ONLY A VERY LIMITED AMOUNT OF WORK HAD BEEN DONE PREVIOUSLY WITH THE MARSHALL EQUIPMENT WITH RESPECT TO ITS SELECTION FOR USE, THE NEW STUDY ALSO PERMITTED AN OPPORTUNITY TO DEVELOP AND IMPROVE TECHNIQUES AND PROCEDURES FOR TESTING AND FOR MAKING A DESIGN ANALYSIS. /AUTHOR/
