PAVEMENT CRACK DETECTION WITH LASERS. FINAL REPORT

This report provides the final details on Research Study 8-18-88-1141. The research was initiated to investigate the capability of using lasers for crack detection in pavements. If such a capability could be developed it would be used to aid in obtaining and evaluating pavement distress and cracking information for the State's pavement management procedures, or PES. The research effort has involved three stages. The first two stages were to determine the crack detection capabilities of the laser probes, used on the Surface Dynamics Profilometer (SDP). The SDP is owned by the State and used for road profile measurements. After experiments indicated that these probes could be used for such detection, a system was developed to further study this capability and to determine how it could be used to implement an automated high speed crack identification system. The results of the first two stages, and a complete description of the research effort is provided in Research Report 1141-1, "The Use of Lasers for Pavement Crack Detection." The third stage has been the development of a system which could be used for implementation of such a system so it's usefulness for PES data collection activities can be determined. This research report describes the final research effort.
