Abstract

This is the Study on Application and Manufacture Technique of Cold-Mix, Cold-Laid type Asphalt Concrete using of Polymer modified asphalt the could be constructed easily and economically on damaged road repaireless for seasons. The modified materials for this study are SBS(Styrene-Butadiene-Styrene). SBR (Styrene-Butadiene-Rubber) and PUR(Polyurethane). The Marshall stability and the value of flow and resistance in water stability degree according to the alternation types and weight percent of modified materials were compared and evaluated on this study. The results of the study show that PUR modified asphalt have improvement of over 150% Marshall stability in AI MS-14 standard and they are evaluated to have the easiness of storage and better working efficiency compared with other types of modified asphalt compound.
