In this study multidepth deflectometers (MDD) were installed in two in-service asphaltic concrete highways (one thick, one thin) to measure the pavement response to vehicle loading. A specifically configured 352 truck was used in the study. It is normally an 18-wheel water tanker but was converted to a 14-wheel tanker for this study. For these tests, dual tires were used on the tandem drive axle with wide base single tires on the tandem trailer axle. Test runs were made under high inflation pressure conditions for the two tire types and the truck speed varying between 5 and 55 mph.

Current operating practice in the trucking industry related to tire pressures and truck tires are summarized. Findings of recent (since 1987) pertiment pavement performance research including both full-scale and analytical pavement response and performance studies are discussed. Pertinent findings developed in previous literature reviews are also included. Regulatory approaches developed by the various states based on information from a telephone survey conducted during July and August 1991 are included. Economic analyses are used to compare the increased annualized bituminous pavement rehabilitation costs with trucking industry benefits. Recommendations regarding the regulation of wide-base truck tires are presented.

The objective of this report is to conduct a review of the present and previously developed work devoted to the study of vehicle/road interaction. In particular, two of the most pressing questions that are to be answered in the area of heavy vehicle-generated road damage deal with the spatial repeatability of dynamic wheel loads produced by heavy road vehicles due to different types of suspension systems and the use of wide-base and dual tires. The outcome of this review, which is a part of the Federal Highway Administration Truck Pavement Interaction research program on truck size and weight, plays a determining role in assessing heavy truck suspension systems, tire configurations, and their contribution to pavement damage.
