Development and Implementation of Overlay Design Procedure, Interim Report No. 2: Asphalt Concrete Stiffness Temperature Relationships and Pavement Distress Modeling


This study consists of two parts. The first part discusses the asphalt concrete stiffness-temperature relationship for Class B mix in Washington State. Two relationships have been suggested. The first one is a composite curve for the stiffness-temperature relationship and the other is a correction factor for the stiffness at any temperature.

The second part of the report is a state-of-the-art review for the fatigue mode of distress for asphalt concrete pavement.
