Impregnated Asphalt Modifier and Multifunctional Asphalt Mixture containing the same
The present invention relates to an impregnated asphalt modifier and a multifunctional asphalt mixture containing the same. To this end, the impregnated asphalt modifier contains: 65-75 wt% of diatomite in which styrene-butadiene rubber (SBR) latex is impregnated in pores of the diatomite; 5-15 wt% of mica; and 15-25 wt% of carbon black. According to the present invention, it is possible to improve resistance against firing flow in the asphalt mixture, and aggregate removal resistance can be greatly improved from the asphalt mixture, thereby reducing causes of porthole formation while improving resistance to crack formation in the asphalt mixture.
본 발명은 함침 아스팔트 개질재 및 이를 포함하는 다기능 아스팔트 혼합물에 관한 것으로, 규조토의 공극 내부에 SBR 라텍스가 함침된 규조토 65~75중량%, 운모 5~15중량% 및 카본블랙 15~25중량%를 포함하는 것을 기술적 특징으로 하며, 아스팔트 혼합물의 소성 흐름에 대한 저항력이 향상되고, 아스팔트 혼합물로부터 골재 탈리 저항성이 크게 향상됨으로써 포트홀 발생 원인이 감소되며, 아스팔트 혼합물의 균열 발생에 대한 저항성이 향상되는 효과가 있다.
