Research on Material Composition Design of Porous Asphalt Mixture Based on Flyaway Characteristics

Abstract Aggregate dispersion is one of the main diseases porous asphalt. Reasonable material composition can effectively reduce occurrence disease. In order to study how determine volume index and mechanical properties mixture from five aspects asphalt, asphalt oil film thickness, coarse aggregate, fiber filler, this paper selects different kinds materials additions, based on benchmark mix ratio, carries out Kentucky test disease Through analysis results, it verified that adopting high-viscosity modified increasing thickness film, adding lime or hydrated as a certain amount enhance anti-flying performance mixture. At same time, article experimental various additives for materials. Finally, comparison schemes improve were formed. terms selection use raw materials, provides guidance construction
