摘要
在路基材料中掺入一些矿渣、粉煤灰、磷石膏等材料可以提高路基材料的各种性能。通过在砂浆的拌和过程直接掺入磷石膏制备水泥基路基材料,系统研究了磷石膏路基材料的基本性能。研究结果表明随着磷石膏的掺量的增加,路基材料的基本抗压强度没有损害,吸水率有显著提高,对工业废料的处理和利用具有重大意义,符合公路路基设计规范和绿色环保的新时代发展理念。
Adding some slag, fly ash, phosphogypsum and other materials into the roadbed materials can improve thevarious properties of the roadbed materials. In this paper, the basic properties of phosphogypsum roadbed materials aresystematically studied by directly mixing phosphogypsum into the mortar mixing process to prepare cement-basedroadbed materials. The results show that with the increase of phosphogypsum content, the basic compressive strengthof the material is not damaged, which conforms to the design specifications of highway roadbed;the water absorption ofthe material is significantly improved, and this phosphogypsum roadbed material can be applied to the pavement of wa-ter-absorbing and permeable pavement, such as areas with more rainy season, park roads, non-machine pavement.The construction of driveway and sponge city road is of great significance to the treatment and utilization of industrialwaste, which is in line with the new era development concept of green environmental protection.
