Asphalt additives with Spent Bleaching clay
The present invention relates to asphalt additives containing calcium waste bleaching clays manufactured by adding calcium salts or calcium hydroxide to waste bleaching clays. Calcium waste bleaching clays-containing asphalt additives of the present invention exhibits excellent binding strength, thereby being able to manufacture asphalt concretes having a high density and low porosity. Accordingly, asphalt concretes using additives of the present invention exerts an excellent peeling prevention effect.
본 발명은 폐백토에 칼슘염 또는 수산화칼슘을 첨가하여 제조한 칼슘 폐백토를 함유하는 아스팔트 첨가제에 관한 것으로, 본 발명의 칼슘 폐백토 함유 아스팔트 첨가제는 뛰어난 결착력을 발휘하기 때문에, 밀도가 높고 공극률이 낮은 아스팔트 콘크리트를 제조할 수 있다. 이로 말미암아 본 발명의 첨가제가 사용된 아스팔트 콘크리트는 우수한 박리방지 효과를 발휘한다.
