Abstract:

The Alabama Department of Transportation (ALDOT) is advancing Balanced Mix Design (BMD) to improve the durability, reliability, and cost-effectiveness of asphalt pavements. To support implementation, a field validation project was conducted on State Route 55 in Covington County, Alabama, using six asphalt mixtures designed to meet target thresholds for the Cracking Tolerance Index (CTIndex) and High-Temperature Indirect Tensile Strength (HT-ITS). Laboratory evaluation included the IDEAL-CT, HT-IDT, and Hamburg Wheel Tracking Test (HWTT) on lab-mixed/lab-compacted (LMLC), hot-compacted plant-mixed/lab-compacted (H-PMLC), and reheated plant-mixed/lab-compacted (RHPMLC) specimens.
