Modified-Asphalt Concrete Composition and Constructing Methods Using Thereof
The present invention relates to a modified asphalt concrete composition, and to a constructing method thereof, wherein the modified asphalt concrete composition is composed of: 1-25 parts by weight of styrene isoprene styrene; 1-25 parts by weight of styrene butadiene styrene; 3-15 parts by weight of recycled rubber powder; 5-30 parts by weight of a modifying agent; 3-20 parts by weight of sodium sulfate; 1-10 parts by weight of a rubber antiaging agent; 2-15 parts by weight of glycerin; 2-15 parts by weight of a compatibilizer; 3-20 parts by weight of nanoceramic particles; and 3-20 parts by weight of an adhesion improver, with respect to 100 parts by weight of asphalt. Therefore, the modified asphalt concrete composition can have excellent durability by having high cohesion and high binding force, avoid easy plastic deformation, aging and/or delamination, prevent infiltrating water and a port hole, and easily conduct a placing process at low costs.
본 발명은 아스팔트 100중량부 기준으로, 스티렌이소프렌스티렌 1 내지 25중량부; 스티렌부타디엔스티렌1 내지 25중량부; 재생고무분말 3 내지 15중량부; 개질제 5 내지 30중량부; 황산나트륨 3 내지 20중량부; 고무노화방지제 1 내지 10중량부; 글리세린 2 내지 15중량부; 상용화제 2 내지 15중량부; 나노세라믹 입자 3 내지 20중량부; 및 부착증진제 3 내지 20중량부를 포함하는 개질 아스팔트 콘크리트 조성물 및 이의 시공방법에 관한 것이다. 본 발명에 따른 개질 아스팔트 콘크리트 조성물은 고응집력과 고결합력을 구비하여 내구성이 좋고, 소성변형, 노화 및/또는 박리가 쉽게 발생하지 않으면서도, 침투수 및 포트홀을 방지하고, 저비용으로 타설공정을 용이하게 수행할 수 있도록 하는 등의 효과가 있다.
