Abstract:

An investigation was performed to develop and study relationships between nondestructive test NDT results and various pavement parameters such as layer thickness, density, and strength. The use of NDT devices has proven viable for evaluation of conventionally designed rigid and flexible pavements and is seen as a great advance over costly and time-consuming destructive evaluation techniques. These same principles can perhaps be effectively applied to include the evaluation of in-situ soil conditions, unsurfaced design or design verification, and construction quality control. Data for this study were obtained during the construction and traffic testing of a test section built for the purpose of obtaining data to validate and possibly reduce present criteria or develop new criteria for design of roads subjected to the heavy wheel loads associated with a proposed MX missile transporter. The test section measured 250 ft. long by 50 ft. wide by 6 ft. deep and consisted of three traffic lanes with five items per lane. Materials used in constructing the test section included limestone, buckshot clay, silt, Blend I, and Blend II. The blended soils were put together at the Waterways Experiment Station WES to simulate gradations anticipated in the proposed construction area. Types of surfacing included unsurfaced blended soils, crushed limestone and silt, cement-stabilized blended soils, lean mix concrete batched from blended soil, and single- and double-bituminous surface treatments.
