Mix Proportion Design Method Optimization of Asphalt Mixture for Heavy Load Pavement

Abstract:

Mix proportion design methods of different asphalt mixtures used in China and other countries were taken comparative analysis. Volume indexes were proposed for gradation design of mineral aggregate and road performance parameters for function analysis in structure layers were used to determine optimum asphalt content in accordance with the service requirements and current construction situation of heavy load asphalt pavement in China, and other performance indexes were taken as verification parameters for mix proportion design of asphalt mixture. Consequently, asphalt mixture with optimized design methods can reflect the actual service condition of heavy load asphalt pavement and correspond with the design and construction of heavy load asphalt pavement in China.
