URP track-free asphalt mixture capable of improving skid resistance based on steel slag and preparation method of URP track-free asphalt mixture
The invention relates to a URP track-free asphalt mixture capable of improving skid resistance based on steel slag and a preparation method of the URP track-free asphalt mixture. The URP track-free asphalt mixture comprises mineral aggregate, asphalt and a URP asphalt modifier, the concrete comprises the following components in percentage by mass: 41.9-44 parts of coarse aggregate; 33.4 to 37.5 parts of steel slag; 11.4 to 15 parts of fine aggregate; 7.3 to 11.3 parts of mineral powder; the mass ratio of the asphalt to the mineral aggregate is 0.058 to 0.064; and the mass ratio of the URP asphalt modifier to the mineral aggregate to the asphalt mixture is 0.9-1.2 wt%. According to the rut-free asphalt mixture with lasting skid resistance prepared by the invention, the high-temperature rut resistance can be remarkably improved, specifically, the high-temperature rut resistance can be improved by 10 times or more, and the rut-resistant dynamic stability test index under the condition of 70 DEG C can reach 10000 times/mm or more.
本发明涉及一种基于钢渣提升抗滑性能的URP无车辙沥青混合料及其制备方法，包括矿料、沥青以及URP沥青改性剂；所述按照质量百分比包括以下组份：粗集料41.9至44份；钢渣33.4至37.5份；细集料11.4至15份；矿粉7.3至11.3份；所述沥青和矿料的质量比为0.058至0.064；以及URP沥青改性剂占矿料和沥青混合料的质量比为0.9至1.2wt％。本发明制备得到的抗滑性能持久的无车辙沥青混合料可显著提高高温抗车辙性能，具体可提高10倍以上，且其70℃条件下的抗车辙动稳定度试验指标可达到10000次/mm以上。
