焙烧铝土矿用于生产专用的防滑路面材料,英国最先开始研究,迄今已有二十多年的历史。英国公路研究试验室试验了所有适用材料,有天然的也有人工合成的,最后得出结论:焙烧铝土矿的性能最佳。采用高温焙烧,所用原料相当于耐火材料类A级焙烧品。与其他材料比较,焙烧铝土矿材料在交通频繁的路面,也极难被磨光。测定筑路石料在公路条件下被磨光的程度,国外一般采用“石料磨光值”(polished stone vslue)作为参数。“石料磨光值”越高,抗磨光性
Roasting bauxite for the production of special non-slip pavement materials, the United Kingdom first started research, so far, more than 20 years of history. The British Highway Research Laboratory tested all applicable materials, both natural and synthetic, and concluded that roasting bauxite performs best. The use of high-temperature roasting, the raw materials used is equivalent to refractory A-type roasted products. Compared with other materials, roasting bauxite materials are also extremely difficult to polish on the road with frequent traffic. Determination of road stone is polished in highway conditions, foreign generally use “polished stone vslue” as a parameter. "The higher the value of the stone, the better the polishing resistance
