DETERMINATION AND CLASSIFICATION OF THE IMPORTANT CHARACTERISTICS OF BITUMEN FOR USE IN SURFACE APPLICATIONS, MIXED IN PLACE AND SIMILAR ROAD SURFACES

THE CHARACTERISTICS OF BITUMINOUS MATERIALS WHICH ARE IMPORTANT IN THE CONSTRUCTION OF EARTH, GRAVEL, BROKEN STONE OR MACADAM, AND MIXED BITUMINOUS ROADS ARE DISCUSSED. THE METHODS OF TESTS FOR THESE CHARACTERISTICS ARE DESCRIBED. THE TYPE OF BITUMEN TO BE SELECTED DEPENDS LARGELY UPON DENSITY OF SURFACE AND RELATIVE SIZE OF VOIDS. TARS OF LOW VISCOSITY, AND LOW PITCH CONTENT, OR PETROLEUM PRODUCTS OF LOW VISCOSITY, LOW CEMENTING VALUE AND SLOW DRYING QUALITY SHOULD BE USED ON CLAY, SAND-CLAY, LOAM, LOAM GRAVEL OR FOR PRIMING COURSE ON WATER BOUND MACADAM ROADS, SINCE SUCH ROADS ARE DENSE AND HAVE RELATIVELY SMALL VOIDS. ON MORE OPEN ROAD SURFACES, SUCH AS SAND, SAND-GRAVEL, OR MACADAM WHICH HAS BEEN PRIMED WITH LOW VISCOSITY MATERIALS, TARS OF HIGH VISCOSITY AND HIGH PITCH CONTENT OR PETROLEUM PRODUCTS OF HIGH VISCOSITY, HIGH CEMENTING VALUE, AND QUICK DRYING QUALITY SHOULD BE USED.
