Responses of Prototype Flexible Pavements Subjected to Repetitive and Static Loads
The report describes the details involved in constructing and testing two three-layer prototype flexible pavements and the results of static and dynamic load tests conducted on the pavements at 70 degrees are presented. The prototype pavements were identically constructed in twin 10 ft. by 10 ft. concrete test pits with the exception that the asphalt concrete layers were of a different thickness. Static loading and two different configurations of a haversine loading function were utilized in the testing program. The pavement's responses were measured in terms of resilient and accumulated surface deflection and surface and subsurface strain. In general it was found that a linear relationship existed between load level and response for each type test. A significant amount of time dependent behavior was exhibited by the pavements during the static load tests and during dynamic testing at the lower ratio of load duration to rest period. Accumulative deformation was found to be more pronounced in the thicker pavement and at locations on the surface close to load center.
