Brief Description of Research Project

In order to assess the construction issues and characterize the long-term performance of the proposed CCP, three CCP test cells made with and without fiber as part of a larger project that will be constructed in Scott County, Missouri, will be designed and tested. Table 1 shows the typical characteristics of the three tested cells of CCP that will be designed with different panel sizes with and without structural synthetic macro fibers. Contractor will be paving 24 feet wide. 

The study aims at determining the performance of designed CCP mixtures given special design features and durability of surface texture through field implementation and detailed laboratory testing. The primary performance characteristics include mechanical properties, drying shrinkage, durability, optimum joint spacing, and enhancement of joint load transfer gained from fiber-reinforcement of the pavement.
