In recent years, chip seal has gained increasing popularity as one of the pavement preservation techniques. It has been found to be a cost-effective strategy in various projects. However, there are some aspects that remain unclear, such as the precise asphalt application ratio in chip seal and its performance under different conditions. Specifically, the lack of a test method for chip seal's tensile and shear bond performance contributes to this uncertainty. Therefore, the primary objective of this dissertation is twofold: firstly, to develop a laboratory performance evaluation of chip seal, and secondly, to analyze the factors influencing its performance using the DEM (Discrete Element Method) modeling approach. By accomplishing these goals, we seek to shed light on the reasons behind chip seal's performance and identify the factors that significantly impact its effectiveness.
