Effects of Parameters Designed by Bailey Method on the Property of Porous Asphalt Mixture

摘要

Based on the Bailey method for aggregate grading design and evaluation, the parameter "reserved voidage" is used in porous asphalt method design. The paper studies the relationship between the three parameters (reserved voidage, blend by volume of the coarse aggregates totaling 100.0% and chosen unit weight of coarse aggregate) and the pavement performances, such as deformation, resistance at high temperature, low-temperature anti-cracking and moisture susceptibility of porous asphalt mixture. The test results indicate that the porous asphalt mixture designed by the modified Bailey Method is of the characteristics of air void easier to control and superior performance.
