Abstract:
FUNDAMENTAL PRECAUTIONS FOR SUCCESSFUL BITUMINOUS MACADAM PAVEMENT DESIGN AND CONSTRUCTION ARE DISCUSSED IN THE LIGHT OF FIELD OBSERVATIONS. OF PRIME IMPORTANCE IS THE PREPARATION OF THE SUBBASE UPON WHICH THE BASE COURSE OF CRUSHED STONE IS TO BE PLACED. ANOTHER ESSENTIAL INGREDIENT IN CONSTRUCTION IS THE PLACING OF SUFFICIENT SHOULDER ALONG THE SIDE LINES TO HOLD THE CRUSHED STONE COURSES. THE PENETRATION COURSE OF STONE SHOULD BE UNIFORM IN DEPTH TO ENSURE THE BEST RESULTS. THE BASE COURSE OF CRUSHED STONE SHOULD BBE FILLED WITH SAND OR CRUSHER DUST. STREAKS IN THE PENETRATION COURSE OF STONE SHOULD BE PENETRATED WITH A HAND HOSE AND NOT LEFT FOR THE SEAL COAT TO COVER UP. IN ADDITION TO SKILLFUL ROLLING REQUIRED IN THE CONSTRUCTION OF A GOOD BITUMINOUS MACADAM, IT IS ESSENTIAL THAT THE PAVEMENT SECURE SUFFICIENT ROLLING TO THOROUGHLY COMPACT THE STONE. CONSTANT CARE SHOULD BE TAKEN DURING THE WHOLE CONSTRUCTION PROCESS AND FAULTS CORRECTED AS THEY OCCUR.
