Cement stabilized macadam capable of compositely regulating shrinkage and preparation method of cement stabilized macadam
The invention discloses cement stabilized macadam capable of compositely regulating shrinkage. The cement stabilized macadam is prepared from the following raw materials in percentage by weight: cement, water, macadam, steel slag, polyethylene glycol, super absorbent resin and silica fume. The preparation method comprises the following steps: S1, adding polyethylene glycol into mixing water, stirring and dispersing to form a solution, adding steel slag into the solution, stirring, and soaking for a certain time to obtain a steel slag and polyethylene glycol mixture for later use; s2, adding the super absorbent resin into the mixing water, and stirring while adding the super absorbent resin to obtain a super absorbent resin gel for later use; s3, mixing and blending the steel slag polyethylene glycol mixture, the super absorbent resin gel and the gravel, adding the cement and the silica fume for blending, and finally adding the rest of water for blending, so as to obtain the cement stabilized gravel capable of compositely regulating and controlling shrinkage. The shrinkage deformation of the cement stabilized macadam can be compositely regulated and controlled from temperature shrinkage and dry shrinkage, so that the formation and development of shrinkage cracking of the cement stabilized macadam are inhibited, and the use performance of pavement quality is improved.
本发明公开了一种复合调控收缩的水泥稳定碎石，包括以下重量百分比的原料制成：水泥、水、碎石、钢渣、聚乙二醇、高吸水树脂、硅灰。本发明还公开了其制备方法，包括：S1：将聚乙二醇加入拌和水搅拌分散成溶液，再把钢渣投入溶液搅拌，并浸泡一定时间，得到钢渣聚乙二醇混合物备用；S2：将高吸水树脂加入拌和水，边加高吸水树脂边搅拌，得到高吸水树脂凝胶体备用；S3：将钢渣聚乙二醇混合物、高吸水树脂凝胶体和碎石混合并拌和，加入水泥与硅灰拌和，最后加入余下的水拌和，即可得到复合调控收缩的水泥稳定碎石。本发明能够从温缩和干缩复合调控水泥稳定碎石的收缩变形，以抑制水泥稳定碎石收缩开裂的形成和发展，提高路面品质的使用性能。
