Project description

The objective of this study is to provide specific inputs and guidance in the selection and specification of coefficient of thermal expansion (CTE) for portland cement concrete (PCC) pavement design and construction. The new pavement design methodology has the potential to provide pavement designs that will perform more predictably than current designs and avoid potential issues that might cause premature pavement failure. By appropriately calibrating the new American Association of State Highway and Transportation Officials (AASHTO) pavement design methodology, the Department will be able to avoid costly premature pavement failures and better optimize its pavement investments.
