The present invention relates to a high-performance asphalt mixture used for asphalt pavement of roads, which comprises: 93.3 to 94.3 parts by weight of general aggregate with the largest aggregate particle size of 13 mm; 5.6 to 6.2 parts by weight of asphalt; and 0.1 to 0.5 parts by weight of vegetable fiber additives, wherein the general aggregate includes 65 to 80 parts by weight of coarse aggregate having a particle size of 5 mm or more, and 10 to 14 parts by weight of fine aggregate having a particle size of 2.5 to 5 mm based on 100 parts by weight of the total. According to the present invention, as the interlocking between the aggregates is maximized by adjusting the mixing ratio of the general aggregates, plastic deformation resistance against wheel load of a vehicle is remarkably increased. In addition, as the content of asphalt is increased by adjusting the mixing ratio of the general aggregate to sufficiently secure an inflow space of asphalt, crack resistance is remarkably increased. In addition, manufacturing cost does not increase significantly by using general aggregate and asphalt pavement is easily possible even in areas where it is difficult to apply crushed stone mastic asphalt pavement, thereby securing commonality of asphalt pavement.
본 발명은 도로의 아스팔트 포장에 사용되는 고성능 아스팔트 혼합물에 관한 것으로서, 골재최대입도치수 13mm인 일반골재 93.3~94.3 중량부와, 아스팔트 5.6~6.2 중량부와, 식물성 섬유첨가제 0.1~0.5 중량부를 포함하되, 상기 일반골재는 전체 100 중량부에 대해 입도치수 5mm 이상인 굵은골재 65~80 중량부와, 입도치수 2.5~5mm 인 잔골재 10~14 중량부를 포함하는 것을 특징으로 한다. 상기와 같은 본 발명에 의하면, 일반골재의 배합비율을 조절하여 골재 간의 인터록킹이 최대화되도록 함에 따라 차륜 하중에 대한 소성변형 저항성이 현저하게 향상된다. 또한, 일반골재의 배합비율을 조절하여 아스팔트의 유입공간을 충분히 확보하여 아스팔트의 함량을 증가시킴에 따라 균열 저항성이 현저하게 향상된다. 아울러, 일반골재를 사용함에 따라 제조비용이 크게 증가하지 않으며, 쇄석 매스틱 아스팔트 포장의 적용이 어려운 지역에서도 이를 통해 쉽게 아스팔트 포장이 가능하므로 아스팔트 포장의 공용성을 확보할 수 있게 된다.
