Phosphogypsum composite modified material for improving performance of asphalt mixture
The invention discloses an ardealite composite modified material for improving the performance of an asphalt mixture, which takes phosphorus chemical waste ardealite as a main material and is blended with rubber resin, a macromolecular resin material and an asphalt material according to a certain proportion. The blending ratio (range) of the phosphogypsum to the rubber resin to the asphalt to the macromolecular resin is (70%-80%): (0%-5%): (10%-15%): (0%-10%); and mixing and processing at the temperature of 110-150 DEG C to obtain the product. The high-temperature stability, the residual stability in a soaking Marshall test, the residual strength ratio in a freeze-thaw splitting test and the Marshall stability of an asphalt mixture prepared by mixing the phosphogypsum composite modified material prepared by the invention are remarkably improved.
本发明公开了一种提高沥青混合料性能的磷石膏复合改性材料，以磷化工废弃物磷石膏为主要材料，掺配一定比例的橡胶树脂、高分子树脂材料、沥青材料；其掺配比例(范围)为磷石膏：橡胶树脂：沥青：高分子树脂＝70％～80％：0％～5％：10％～15％：0％～10％；在110℃～150℃环境下拌和加工而成；通过采用本发明制备的磷石膏复合改性材料拌制的沥青混合料，其高温稳定性能、浸水马歇尔试验残留稳定度、冻融劈裂试验的残留强度比、马歇尔稳定度显著提高。
