SIS PSMA Modified-Resin Stone Mastic Asphalt Concrete Compositions Using Stylene Isoprene Stylene and Constructing Methods Using Thereof

摘要

The present invention is based on 100 parts by weight of asphalt, styrene isoprene styrene 1 to 25 parts by weight; Petroleum resin 1 to 25 parts by weight; Aggregate 500 to 2,000 parts by weight; 30 to 150 parts by weight of fine powder aggregate; 0.5 to 10 parts by weight of a modifier; Cellulose fiber 0.1 to 2 parts by weight; And it provides a polymer modified crushed stone mastic asphalt concrete composition containing 0.1 to 2 parts by weight of wax and a construction method using the same. The polymer modified crushed stone mastic asphalt concrete composition according to the present invention, specifically, the polymer modified crushed stone mastic asphalt concrete composition using SIS has good durability, and does not easily undergo plastic deformation, aging and/or peeling, and is cast at low cost. In addition to being able to easily perform the process, there is an effect such as to reduce the plastic deformation that occurs rapidly in summer and the like.
