The polymers, low-density polyethylene (LDPE) and styrene-butadiene-styrene(SBS) -modified asphalt mixtures are advancedasphalt pavement materials in which 3 ~ 6% of them, and/or some other additive, by weight of total binder are added. Thepurpose of modifying asphalt material is to improve typical weakness such as rutting and cracking resistance of normal asphaltmixtures. These materials have been proved to show many advantages and practical applicability in the plant and field. Wetprocessed PMA binder and/or dry processed asphalt mixtures are developed as field products for many years. The objectiveof this paper is to show the characteristics of the LDPE and SBS-modified asphalt mixtures by comprehensive evaluation andcomparison with those of normal asphalt mixtures.
