REHABILITATION OF PLAIN PORTLAND CEMENT CONCRETE PAVEMENTS WITH ASPHALTIC CONCRETE OVERLAYS

One of the main problems associated with asphaltic concrete overlays over jointed concrete pavements is the occurrence of reflection cracks over the old joints. Past practice has been to place thick overlays to delay the prossibility of water entering the pavement system as well as to reduce the number of reflection cracks. Many of the concrete pavements in Georgia are structurally adequate and would not require thick overlays if the deterioration due to the loss of base support could be stopped. Thick overlays, therefore, would not be justifiable from a structural viewpoint. In order to find an answer to the problem of reflection cracking, the Georgia Department of Transportation initiated a research study in 1975 to evaluate, in the field, the performance of several portland cement concrete and asphaltic concrete overlay systems. The paper discusses the design, construction and performance of the asphaltic concrete overlay test sections.
