Assessment of Asphalt Shear Rutting Test Method to Improve the Performance of ADOT Asphalt Mixes

A balanced mix design (BMD) approach to asphalt mixtures that considers both cracking and rutting resistance is important to minimize road-maintenance costs and extend the life of the pavement. Arizona Department of Transportation (ADOT) is currently engaged in a research project to assess innovative test methods to predict the cracking resistance of ADOT asphalt mixes across the state. The ADOT Materials Laboratory (Lab) obtained an apparatus known as the IDEAL-RT, which is used to conduct the shear rutting tests that predict the resistance to rutting (permanent deformation) of asphalt mixes. The Lab is interested in this test method to determine if it is acceptable for regular use in future rutting-resistance assessments of ADOT asphalt mixes. This project will focus on assessing the IDEAL-RT as a tool for predicting rutting resistance.
