Abstract:

The purpose of this investigation was accomplished by the construction and traffic testing of a specially designed test road. This two lane test road was subdivided into nine asphalt concrete AC surfaced and six aggregate or native surfaced test items. A plan view of the test road is shown in Figure 1. The test road was subjected to both loaded and unloaded 18-wheeled log trucks operating in two distinct traffic lanes. Test traffic was applied with the trucks operating at low and high tire pressures. Testing consisted of laboratory tests on the soil, aggregate and asphalt pavement elements instrumentation measurements of pavement temperature, and deflection and strain resulting from applied dynamic test traffic and falling weight deflectometer loads and field-in-place measurements before, during, and after traffic to document the performance of the test road.
