LOW COST, LOW TYPE ASPHALT SURFACED ROADS IN THE WESTERN REGIONS OF THE U.S.A.

MAJOR HIGHWAYS BUILT IN THE U.S.A. ARE SURFACED WITH A HIGH TYPE ASPHALTIC CONCRETE PAVEMENT OR A PORTLAND CEMENT CONCRETE PAVEMENT WHEN HIGH TRAFFIC VOLUMES ARE EXPECTED. HOWEVER, WHEN NEW HIGHWAY ROUTES ARE CONSTRUCTED, HIGH TRAFFIC VOLUMES MAY NOT DEVELOP FOR A NUMBER OF YEARS. IN SUCH CASES, STAGE CONSTRUCTION STARTING WITH LOW TYPE ASPHALT SURFACES MAY SERVE TRAFFIC EFFECTIVELY AND AT LOWER COSTS. ADDITIONAL THICKNESSES OF PAVEMENT CAN BE ADDED WHEN HIGH TRAFFIC VOLUMES DEVELOP. IT IS ESSENTIAL THAT ALL ROADS OF ANY IMPORTANCE HAVE ALL WEATHER, DUSTLESS SURFACES. IN MOST AREAS, LOCAL AGGREGATES SUITABLE FOR BASE COURSES AND LOW TYPE, LOW COST ASPHALT SURFACES CAN BE FOUND AND USED. THESE LOW COST SURFACES ON ADEQUATE BASE COURSES WILL GIVE GOOD SERVICE TO LOW OR MEDIUM TRAFFIC VOLUMES RANGING FROM 50 TO 250 VEHICLES PER DAY. INTERMEDIATE CLASSES OF ASPHALT PAVEMENTS SUCH AS BITUMINOUS PENETRATION MACADAM MATS OR PLANT MIX SURFACES CAN CARRY TRAFFIC VOLUMES UP TO 500 OR 600 VEHICLES PER DAY. THE BENEFITS ARE REVIEWED OF ASPHALT SURFACE ROADS. /AUTHOR/
