Cement stabilized macadam mixture doped with waste incineration slag
The invention discloses a cement stabilized macadam mixture doped with waste incineration slag. The cement stabilized macadam mixture is prepared by the following steps: preparing 0-2.36 mm waste incineration slag, cement, fly ash, an excitant and water according to a mass percentage ratio of 32.6%: 6.5%:32.5%:7.8%:20.6%, mixing, pelletizing, curing to obtain 4.75-13.2 mm slag pellets, and uniformly mixing with 0-4.75 mm waste incineration slag, cement, aggregate and water to obtain the mixture. According to the invention, the slag pellet prepared by the invention meets the technical requirements of the existing highway pavement base specification on coarse aggregate, so that the condition that the waste incineration slag cannot be used as the coarse aggregate due to substandard crushing value is changed, the resource utilization rate of the waste incineration slag in the highway base is greatly improved, and the slag pellet conforms to the green ecological characteristic, and is suitable for base layer materials of heavy, medium and light traffic pavements of roads of two or less levels; and the the slag pellet is used for replacing part of coarse aggregate of the cement stabilized macadam mixture, so that the use of natural aggregate is reduced, and the environmental protection is promoted.
本发明公开了一种掺入垃圾焚烧炉渣的水泥稳定碎石混合料，以质量百分比计，将0~2.36mm垃圾焚烧炉渣:水泥:粉煤灰:激发剂:水按照32.6%:6.5%:32.5%:7.8%:20.6%进行备料、拌和、成球和养生，制成4.75mm~13.2mm炉渣球团，再与0~4.75mm垃圾焚烧炉渣、水泥、集料、水一起拌合均匀，得到所述的混合料。本发明制得的炉渣球团满足现行公路路面基层规范对粗集料的技术要求，从而改变垃圾焚烧炉渣因压碎值不达标而无法用作粗集料的状况，使得垃圾焚烧炉渣在公路基层中的资源化利用率大幅提高，符合绿色生态特色，适用于二级及二级以下等级公路重、中等和轻交通路面的基层材料，同时，本发明以炉渣球团替代水泥稳定碎石混合料的部分粗集料，有利于减少天然集料的使用和促进环境保护。
