Optimal Air Void for Strength and Permeability of Porous Asphalt Mixture Based on Topological Optimization

Publication: ICCTP 2011: Towards Sustainable Transportation Systems

Abstract

Strength and permeability of porous asphalt mixtures mostly depend on the air voids; however the two factors contradict each other. In order to research the relationship between strength and permeability, a finite element model was established to describe the meso-voids in porous asphalt mixtures, and the topological optimization was applied to obtain the optimal air void. It is indicated that while the strain energy increases with air voids, the strength decreases with the strain energy, so the strength decreases with air voids. When the air void content is larger than 12%, the strength is tending towards stability. However, the strength decreases rapidly when air void content is larger than 22%. The permeability also increases with the air void content and increases rapidly when air void content is larger than 19%. Therefore, the suggested air void content for porous asphalt mixture is 19%∼22% to satisfy the requirements of strength and permeability.
