Abstract
Present stripping mechanisms fail to specify the source of water necessary for stripping to start and progress with time. Finding the water source and route to the pavement interior is of great significance to efforts seeking a preventive measure against stripping. Investigation of the influence of construction-induced cracks, referred to as checking, on pavement resistance to stripping is reported. A new field-compaction technique was used to produce a crack-free, asphalt concrete surface that offered a much higher resistance to stripping than conventionally compacted surfaces. Cores recovered from field-compacted pavements were used throughout the investigation. The results of the experimental investigation indicated that compaction technique has a significant influence on the mix resistance to stripping. Vacuum saturation, used as part of the moisture conditioning procedure, has in the past obscured the influence of construction induced cracks on stripping susceptibility.
