Evaluation of Maintenance/Rehabilitation Alternatives for Continuously Reinforced Concrete Pavement

摘要

An evaluation of several maintenance/rehabilitation methods for an Interstate Continuously Reinforced Concrete Pavement (CRCP) in Illinois has been conducted. Maintenance and rehabilitation needs are increasing rapidly due to aging and heavy truck traffic on the Interstate system. Thus, efficient methods are greatly needed. The design, construction, performance, and costs of several maintenance and rehabilitation methods were evaluated including patching, cement grout and asphalt undersealing, epoxying of cracks, and an asphalt overlay. Information gathered will be very useful in the development of future maintenance activities and rehabilitation projects. Nondestructive Testing (NDT) deflections, reflection cracking, cost, and statistical analyses were used to evaluate the maintenance and rehabilitation methods.
