TEMPORARY RELAXATION OF AXLE WEIGHT LIMITS

AT THE REQUEST OF THE DEPARTMENT OF TRANSPORT A BRIEF THEORETICAL STUDY WAS MADE OF THE PROBABLE TECHNICAL AND ECONOMIC EFFECTS OF A 20 PER CENT INCREASE IN AXLE-LOADING LIMITS ON ROADS. THIS PRELIMINARY STUDY INDICATED THAT IF AN INCREASE OF 20 PER CENT WERE ALLOWED IN AXLE LOADS THE REDUCTION IN THE SERVICE LIFE OF A ROAD COULD BE AS MUCH AS 50 PER CENT. ALSO, THE THICKNESS OF A NEW ROAD DESIGNED TO CARRY THE INCREASED AXLE LOADS FOR THE FULL NORMAL LIFE WOULD HAVE TO BE APPROXIMATELY 10 PER CENT GREATER THAN THAT REQUIRED UNDER THE PRESENT AXLE-WEIGHT LIMITS, AND HIGHER QUALITY SURFACING AND BASE MATERIALS WOULD BE NECESSARY. A CONSIDERABLE INCREASE IN THE CONSTRUCTION AND MAINTENANCE OF ROADS WOULD RESULT IN EITHER CASE. /ARTICLE/
