This study evaluated 6 specific preventive treatments. Four treatments are for asphalt concrete surfaced (flexible) pavements: chip seals; crack sealing; slurry seals; and thin overlays. Two treatments are for portland cement concrete surfaced pavements: joint and crack sealing; and undersealing. Performance of the pavement sections with the treatments was compared with the performance of a similar pavement section without the treatment. Performance is measured in terms of pavement distress, roughness profile, surface friction, and structural capacity. All of the flexible pavement test sections and most of the rigid pavement test sections have been constructed. Performance data are being collected. This report discusses the experimental design, project selection, construction, data collection, analysis, and future activities of the pavement maintenance effectiveness project.
This is accomplished in seven major parts, and 42 component chapters, ranging from the evolution of pavement management to date requirements to determining needs and priority programming of rehabilitation and maintenance, followed by ...

... depth to detect debonding of overlays. The need for using couplant in ultrasound technology causes serious limitation at this stage. On the other hand, eddy current technology held no promise for pavement maintenance effectiveness .
The lack of cost - effectiveness information has been one of the reasons preventive maintenance has not been included in some pavement management systems . There is little information available which defines the best time in the service ...
