Asphalt Flexible Sand Color Asphalt Concrete Composition for Pavement and Construction Methods Using Thereof
The present invention provides a flexible sand color asphalt concrete composition and a construction method thereof. The flexible sand color asphalt concrete composition comprises: 1,000 to 1,500 parts by weight of a fine aggregate; 8 to 15 parts by weight of a rubber powder; 10 to 40 parts by weight of a filler; 10 to 30 parts by weight of a slaked lime; 20 to 70 parts by weight of a pigment; 1 to 25 parts by weight of petroleum resin; 2 to 15 parts by weight of a rubber antiaging agent; 15 to 40 parts by weight of nonslip particles; 2 to 15 parts by weight of an ultraviolet absorbent; 2 to 15 parts by weight of a compatibilizer; 1 to 10 parts by weight of a stabilizer; and 0.5 to 10 parts by weight of a performance improver, based on 100 parts by weight of asphalt. A flexible sand color asphalt concrete composition for pavement according to the present invention has excellent low temperature crack resistance, sliding (friction) resistance, and a snow-melting effect, prevents water from ponding by securing excellent surface smoothness during a construction, and has an impact absorbing property which absorbs impact to some extent when a pedestrian falls by maximizing ductility of a material.
본 발명은 아스팔트 100중량부 기준으로, 잔골재 1,000 내지 1,500중량부; 고무분말 8 내지 15중량부; 충진제 10 내지 40중량부; 소석회 10 내지 30중량부; 안료 20 내지 70중량부; 석유수지 1 내지 25중량부; 고무노화방지제 2 내지 15중량부; 논슬립입자 15 내지 40중량부; 자외선 흡수제 2 내지 15중량부; 상용화제 2 내지 15중량부; 안정제 1 내지 10중량부; 및 성능개선제 0.5 내지 10중량부를 포함하는 연성샌드 칼라 아스팔트 콘크리트 조성물 및 이의 시공방법을 제공한다. 본 발명에 따른 보도용 연성샌드 칼라 아스팔트 콘크리트 조성물은 저온균열 저항성, 미끄럼(마찰) 저항성 및 융설효과가 우수하며, 시공 시 우수한 평탄성(surface smoothness)을 확보함으로써 물고임을 방지하고, 재료의 연성을 극대화시켜 보행자의 낙상 시 충격을 어느 정도 흡수하는 충격흡수성을 갖는 효과가 있다.
