Permissible Weight Limits for Construction Vehicles on Finished and Unfinished Pavements: Final Report

Report No: 79-R48

Published in 1979

About the report:

The report summarizes studies directed at developing guidelines for controlling the use of partially completed pavements by heavy construction equipment. It is shown that the damaging effects of flotation tires may be analyzed in the same manner as those of conventional dual tires, and that the AASHTO traffic equivalencies for such dual tires are applicable to the flotation tires. Tables of traffic equivalencies for various single-axle loads and the maximum permissible 18-kip (8,160-kg) equivalent repetitions for a variety of thickness indices are given as guidelines for field engineers. The development of specifications limiting the travel of construction equipment on various pavement layers was not considered to be an objective of the present study and is to be accomplished in an implementation phase.
