The Research on Compaction Characteristics of Rubber Asphalt Mixture

Abstract:

Through the crush value test and combustion method test to analyze the relationship between needle flake content and crush value，and analyze the affection to the status of broken at compaction procession .Through the use of static pressure, gyratory compaction and Marshall compaction this three different molding methods of rubber asphalt mixture specimen shape.At the same time, analyze the variation of volume parameters and combination with the methods of specimen trimming to analyze its porosity distribution. At the same time, forming the sample volume parameters and combination of slices to analyze the porosity distribution of three different ways. The same time, through combustion method to analyze the impact of molding methods on rubber asphalt mixture's compaction characteristics.
