HIGHWAY PAVING: WHICH WILL IT BE - ASPHALT OR CONCRETE?

SOME OF THE VARIABLES INVOLVED IN THE NECESSARY DECISION- MAKING FOR ASPHALT OR CONCRETE HIGHWAY PAVEMENTS ARE DISCUSSED. IT IS POINTED OUT THAT EVEN WHEN COMPARATIVE FIGURES ARE AVAILABLE, THE CIRCUMSTANCES AND CONDITIONS UNDER WHICH A ROAD IS BUILT MAY BE SO SPECIALIZED THAT THE RESULTS CANNOT BE SAFELY GENERALIZED TO APPLY EVERYWHERE. COSTS VARY CONSTANTLY FROM AREA TO AREA & ARE DEPENDENT ON THE LOGISTICS OF SUPPLY, THE PRICE OF AGGREGATE, STEEL, LABOR & OTHER ELEMENTS IN THE POTENTIAL BID PRICE. THE TYPE & VOLUME OF TRAFFIC TO BE CARRIED WILL AFFECT THE THICKNESS OF THE PAVEMENT REQUIRED TO SUPPORT IT EFFICIENTLY AND ECONOMICALLY. COST PER MILE FIGURES ARE AFFECTED BY THE DEGREE OF CONTRACTOR INTEREST IN A JOB, THE EXTENT OF HIS EXPERIENCE, CLIMATE, THE TYPE, CONDITIONS, AVAILABILITY AND PROXIMITY OF MACHINERY AND EQUIPMENT AND ESTIMATED MAINTENANCE COSTS. IT IS CONCLUDED THAT THE INFLATIONARY SPIRAL, SHORTAGE OF MATERIALS, NEW DEVELOPMENTS IN MACHINERY, METHODS AND DESIGN CALL FOR AN OPEN MIND AND AN ALMOST DAILY REAPPRAISAL OF THE FACTORS WHICH INFLUENCE DECISION MAKING.
