Abstract

Abstract: Due to the large proportion of coarse aggregate, the key index void ratio of Large stone porous asphalt mixture is difficult to control in the production process. In order to solve this problem, this paper first carries out the raw material testing and mixture design of LSPM-30; then carries out the comparative analysis of the calculation method and Corelock method for the volume index of Large stone porous asphalt mixture; finally, according to the sample test and porosity calculation, the difference of porosity between the laboratory sample and the field sample is calculated, and based on this, the porosity of the field and laboratory sample is proposed control requirements.
