VEHICLE WEIGHT REGULATION AND THE EFFECTS OF INCREASED LOADING ON PAVEMENTS

THE REACTION TO LOADING OF FLEXIBLE AND RIGID PAVEMENTS, THE EFFECTS OF DIFFERENT WHEEL LOADS ON PAVEMENT LIFE, THEIR EQUIVALENCE IN TERMS OF PAVEMENT DAMAGE, AND THE INFLUENCE OF ADJACENT AXLES, ARE DESCRIBED. INCREASED MAINTENANCE AND STRENGTHENING OVERLAYS ARE NEEDED FOR INCREASED WHEEL LOADS. A 1967 VEHICLE SURVEY SHOWED THE 85 PERCENTILE SINGLE-AXLE LOAD TO BE ABOUT 22 KIPS, SO THAT RAISING THE WEIGHT LIMITATION FROM 18 KIPS TO 20 KIPS WOULD ONLY RESULT IN REGULATION OF THOSE TRUCKS WITH 20 KIP SINGLE-AXLES NOW REGARDED AS OVERLOADED. STRICTER ENFORCEMENT MUST ENSURE THAT THERE IS NO UPWARD SHIFT IN THE LOADING SPECTRUM WHEN THE WEIGHT LIMITATIONS ARE RAISED. /AUTHOR/
