Evaluation of Concrete Inlay for Continuously Reinforced Concrete Pavement Rehabilitation
In 1996, WisDOT constructed a concrete inlay test section on I-43 in Manitowoc County. The existing pavement was CRCP constructed in 1978 and was badly deteriorated with punch-outs. In the area of the 2777-foot test section, the existing pavement was removed, the foundation was replaced with a drained system, and an 11-inch JPCP concrete inlay was constructed. The remainder of the project, including a control section, received CRCP patching and an HMA overlay ranging in thickness from 3 to 6 inches. The pavement was evaluated after 14 years in service. The concrete inlay was in excellent condition. Only isolated slab cracking was noted. The 6-inch HMA overlay control section had more distresses, most notably transverse cracking. The PDI values for the test and control sections were 7 and 43, respectively. A series of LCCAs using 1996 construction costs showed that the HMA overlay rehabilitation alternative was more cost-effective than concrete inlay. Because it is not the most cost-effective large-scale pavement rehabilitation alternative, concrete inlay is not recommended for routine use on Wisconsin roadways.
