The Effect of Rubber Crumbs on Marshall Properties for Warm Mix Asphalt

A new pavement technology has been developed in Highway engineering: asphalt production is less susceptible to oxidation and the consequent damages. The warm mix (WMA) produced at a temperature of about (10-40) oC lower than hot paving. This done using one methods producing WMA. Although WMA's performance rather good, according previous studies, as it oxidation, possible modify some its properties different materials, including polymers. Waste tires vehicles are types polymers because their flexible properties. HMA, WMA, WMA modified with proportions (1, 1.5, 2%) rubber crumbs by dry method accomplished this work. Marshall Test volumetric determination performed evaluate performance. results showed that 1% replacement for fine aggregate mixture best compared conventional
