Abstract:In this study multi-depth deflectometers (MDD) were installed in two in-service asphaltic concrete highways (one thick, one thin) to measure the pavement response to vehicle loading. A specially configured 3S2 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.
