摘要巴西中西部地区用于路面施工的红土砾石在城市中心附近已不复存在。因此，越来越需要研究替代材料来取代它。本研究对细粒采石场废弃物的利用进行了评价。采用常规材料和采石场废土混合料进行沥青路面试验。进行了现场试验，以评估这些材料的性能。经过验证，这种废物能够为小容量道路提供相同的性能水平，同时具有环境和经济优势。
AbstractThe lateritic gravel routinely used in the midwest region of Brazil for pavement construction is no longer found near the urban centers. Thus, there is an increasing need for studies of alternative materials to replace it. This study presents an evaluation of the use of fine quarry wastes. An experimental test asphalt pavement was built with conventional materials and a soil–fine quarry waste mixture. Field tests were conducted to assess the behavior of these materials. It was verified that this waste is able to provide the same performance levels for low-volume roads while offering environmental and economic advantages.
