Permeable asphalt mixture as well as preparation method and application thereof
The invention relates to the field of road building materials, and particularly discloses a permeable asphalt mixture as well as a preparation method and application thereof. The permeable asphalt mixture comprises asphalt and mineral aggregate, the mass of the asphalt accounts for 4.5%-5.5% of the mass of the mineral aggregate, the mineral aggregate comprises aggregate and filler, the passing rate of 16 mm sieve pores of the mineral aggregate is 100%, the passing rate of 13.2 mm sieve pores of the mineral aggregate is 95.2%-94.4%, and the passing rate of 9.5 mm sieve pores of the mineral aggregate is 72.8%-72.0%; the preparation method comprises the following steps: heating the asphalt and the mineral aggregate to 170-190 DEG C, and mixing all the components at 150-180 DEG C to obtain a permeable asphalt mixture; the application of the permeable asphalt mixture is as follows: the permeable asphalt mixture is paved, compacted and formed to obtain a permeable pavement. The water-permeable asphalt mixture disclosed by the invention has the advantage of excellent water stability.
本申请涉及公路建筑材料领域，具体公开了一种透水沥青混合料及其制备方法和应用。一种透水沥青混合料，包括沥青和矿料，所述沥青质量为所述矿料质量的4.5%～5.5%，所述矿料包括集料和填料，所述矿料的16mm筛孔通过率100%，13.2mm筛孔通过率为95.2%‑94.4%，9.5mm筛孔通过率72.8%～72.0%；其制备方法为：所述沥青和所述矿料加热至170～190℃，将所有组分进行拌和，拌和温度为150～180℃，得到透水沥青混合料；其应用为：所述透水沥青混合料经摊铺、压实、成型后得到透水性路面。本申请的透水沥青混合料具有水稳定性优异的优点。
