Evaluation of Portland Cement Concrete Pavement Materials, I-265, Jefferson County

Kentucky's rigid pavement utilizes a catalog of rigid pavement designs developed by evaluating both the Kentucky rigid pavement design procedure and the 1986 AASHTO procedure at varying levels of traffic and subgrade strength. As Kentucky anticipates moving toward the use of the proposed NCHRP 1-37A Pavement Design Guide, this new design procedure will require concrete material parameters which have not been previously routinely tested in Kentucky. Using construction site on I-265 in Jefferson County, this project will evaluate parameters for Modulus of Rupture (flexural strength), Modulus of Elasticity, and Coefficient of Thermal Expansion.
