Using the Indirect Tension Test to Evaluate Rut Resistance in Developing Hot-Mix Asphalt Mix Designs

This paper describes how the indirect tension (IDT) strength test, when performed at high temperatures following the recommended protocol, can be used to evaluate the rut resistance of hot-mix asphalt (HMA) mixtures. The suggested procedure is simple, quick, and can be performed using a standard Marshall press without the need of a temperature control chamber. The paper includes a review of the initial development of the high-temperature IDT test, and also discusses how the new, rapid test procedure was developed. Improved guidelines for interpreting the results of the high-temperature IDT test are presented, which include a rule of thumb for accounting for differences in traffic speed. Two case studies are presented in which the IDT test was used to help ensure that HMA designs had sufficient rut resistance for their intended applications.
