Evaluation of Indirect Tensile Test (IDT) Procedures for Low-Temperature Performance of Hot-Mix Asphalt

---

This study evaluates the effectiveness and consistency of Indirect Tensile Test (IDT) procedures in characterizing the low-temperature performance of hot-mix asphalt (HMA). Low-temperature cracking is a critical distress in asphalt pavements, often caused by thermal contraction and inadequate stress relaxation. The IDT test, widely used to determine creep compliance, tensile strength, and fracture properties, is assessed in terms of its sensitivity to testing conditions, specimen preparation, and analysis methods.

Experimental results highlight variability in measured properties due to differences in loading configurations, temperature control, and data interpretation techniques. The study compares multiple IDT-based parameters, including creep compliance and fracture energy, to determine their reliability in predicting field performance. Findings suggest that while the IDT test provides valuable insight into thermal cracking resistance, standardization of procedures is essential to improve repeatability and comparability across laboratories.

The research concludes that optimized IDT protocols can serve as a reliable tool for evaluating low-temperature cracking potential in HMA, supporting better material design and pavement performance prediction.
