Abstract: This research project aims to advance the cracking resistance characterization of asphalt concrete mixtures by integrating a high-resolution, dual-camera imaging system into Balanced Mix Design cracking performance tests, such as the IDEAL-Cracking Test and Overlay Test. The motivation for this study stems from the critical need to improve the durability of asphalt pavements subjected to increasing traffic-induced and environmental stresses. The primary objective is to validate a dual-camera imaging system capable of capturing and quantifying vertical crack growth on both sides of asphalt mixture specimens with high accuracy and repeatability. The research will involve system evaluation, image data analysis, and comparison with conventional test metrics to support asphalt mixture and pavement design. Project tasks include the evaluation of the imaging system, execution of controlled cracking tests, and detailed analysis of crack initiation and propagation patterns. The anticipated outcomes include enhanced insight into cracking behavior across different asphalt mixtures, improved methodologies for assessing material performance, and identification of mixtures with superior crack resistance. By leveraging high-resolution imaging techniques, this research will not only provide a deeper understanding of the mechanisms driving cracking but also facilitate the optimization of asphalt formulations to mitigate such failures. Additionally, the findings could serve as a valuable resource for engineers and policymakers aiming to implement more weather-resilient infrastructure solutions in response to the increasing demands of modern transportation systems.
