Problem Statement
The Michigan Department of Transportation has constructed 110 lane miles of Jointed Plain Concrete Pavement (JPCP) for new or reconstructed freeway projects since 1994. A few projects are experiencing transverse and longitudinal cracking within the first five years after construction.
Research Objectives
The cause may be due to one or more factors including base support, material usage, construction workmanship, traffic loading, and environmental inducement. The projects were constructed with slightly differing specifications and warranty requirements. The cause of the early cracking needs to be determined and corrected. Also, the impacts of the cracking need to be quantified to determine the appropriateness and timeliness of future maintenance and to predict any ramifications on the project's expected design life.
Research Method
N/A
Product
A report of all project activities will be prepared with conclusions and recommendations for correcting similar cracking on future projects.
