TECHNIQUES FOR REHABILITIES PAVEMENTS WITHOUT OVERLAYS--A SYSTEMS ANALYSIS VOLUME 1--ANALYSIS
The objective of the study was to determine the feasibility of a variety of innovative techniques for rehabilitating pavements without using thick overlays and to develop these techniques to the point where they could be implemented. A total of 39 potential techiques were identified. To determine their feasibility a systems decision analysis computer program was developed which utilizes utility theory to simutaneously consider 17 different decision criteria under four main attributes (Cost, Performance, Energy and Impact). Using this utility decision analysis program, a total of 19 techniques demonstrated the capability of solving certain problems better than currently used techniques. Included in the 19 promising techiques are a) use of rejuvinating agents for flexible pavements, b) horizontally-bored sleeper slab and joint restoration for rigid pavements, c) precast joint assemblies for rigid pavements, d) change the location of lane markings, and e) reworked surface of flexible pavement. For other specific problems the program indicated presently used techniuqes are better than any of the potential techniques. And finally, the program revealed that 15 potential techniques did not show any promise at this time. Suggestions for further development, implementation, and research have been made.
