Parent Asphalt Mixture Design of Semi-Flexible Pavement Based on Method of Main Mineral Aggregate Void Filling

Abstract:

Semi-flexible pavement was a type of pavements in good service performance and its material composition belonged to dense-skeleton structure. However, the material composition of its parent asphalt mixture was a form of skeleton-void structure. In order to achieve better volume characteristics and technical performance of parent asphalt mixture, the parent asphalt mixture design method of semi-flexible pavement based on main mineral aggregate void filling was developed. The parent asphalt mixture was studied using Marshall test and the results indicated that all volume parameters and technical performance indicators of parent asphalt mixture completely satisfied the corresponding technical requirements. The effectiveness of method of main mineral aggregate void filling to design parent asphalt mixture was verified.
