Innovative Pavement Maintenance Technology

Colorado Department of Transportation Video VH-412 Innovative Pavement Maintenance Technology An overview of a field demonstration program conducted by Ahmad Ardani of Colorado DOT in April 1998. Ardani presented what SHRP has learned about joint seals in concrete pavements, demonstrated use of a Georgia Fault Meter (to measure differences in elevation across joint seals), and demonstrated use of an Iowa Vacuum Tester (to detect leaks in joint seals), however there were no details in the video, only mention that these things were done during the program. The video briefly demonstrated the step by step use of spray injection pavement patching systems and includes contact information for the Dura Patcher and Roadpatcher systems.
