Abstract

The Hamburg wheel-tracking device can be used to predict the moisture susceptibility of a hot mix asphalt pavement. The test results are influenced by testing temperature, asphalt cement stiffness, air void content, short-term aging, and the presence of lime. The variables are important to control in the laboratory environment to ensure repeatability. Additionally, these variables are also considered important to the moisture resistance of a pavement in the field.
