Reflective asphalt mixture and preparation method thereof
The invention discloses a reflective asphalt mixture and a preparation method thereof, and aims to improve the reflective characteristic of the surface of an asphalt concrete road by doping soda-limesilicate glass beads into the asphalt mixture. 2% of slaked lime is used for replacing mineral powder in equal mass, so that the problem of insufficient adhesion between asphalt and glass beads is solved, and the service life of the asphalt mixture is prolonged; the mixture is simple in preparation process, convenient to operate and relatively low in preparation cost; road lighting power consumption can be reduced, energy is saved, consumption is reduced, and the concept of green energy conservation, environmental protection and sustainable development is met; the asphalt mixture is prepared from the following components in parts by mass: 4.3 to 5.3 parts of matrix asphalt, 0.6 to 5.0 parts of soda-lime silicate glass beads, 61.5 to 63.7 parts of coarse aggregate, 24.0 to 26.3 parts of fine aggregate, 1.8 to 2.0 parts of slaked lime and 2.8 to 2.9 parts of mineral powder.
本发明公开了一种反光沥青混合料及其制备方法，目的在于，通过在沥青混合料中掺加钠钙硅酸盐玻璃珠，提升沥青混凝土路表面的反光特性；将消石灰以2％等质量取代矿粉，解决沥青与玻璃珠粘附性不足的问题，延长沥青混合料的使用寿命；混合料制备工艺简单，操作方便，制备成本较低；可以减少道路照明用电，节能减耗，符合绿色节能环保和可持续发展理念；沥青混合料按质量份计，包括4.3～5.3份的基质沥青、0.6～5.0份的钠钙硅酸盐玻璃珠、61.5～63.7份的粗集料、24.0～26.3份的细集料、1.8～2.0份的消石灰、2.8～2.9份的矿粉。
