Construction method of stabilized macadam self-curing cement layer pavement
The invention discloses a construction method of a stabilized macadam self-curing cement layer pavement, and belongs to the technical field of road construction. The polyoxyethylene fatty alcohol ether and the polyacrylate are compounded to serve as a self-curing agent to be added into the cement stabilized macadam, the bonding performance between materials can be further improved, the brittleness problem of the cement stabilized macadam material is solved in a curing mode, a cement stabilized macadam layer is endowed with certain elasticity, and the sensitivity to temeprature and humidity is reduced, meanwhile, the polyformaldehyde fibers can further enhance the tensile strength and the compressive strength, the self-curing effect of the cement stabilized macadam mixed layer is guaranteed, and then cracks are reduced. According to the method, the joint laying delay time during laying of the cement stabilized macadam layer can be prolonged to 10 hours from current about 4 hours, the problem of time limitation during construction of joint laying is solved, and continuous construction of a longer section is guaranteed.
本发明公开了一种稳定碎石自养护水泥层路面施工方法，属于道路施工技术领域。本发明利用聚氧乙烯脂肪醇醚与聚丙烯酸酯复配后，作为自养护剂加入水泥稳定碎石中，能够进一步提高材料间的粘结性能，并通过养护方式改善水泥稳定碎石材料脆性问题，赋予水泥稳定碎石层一定的弹性，降低其对温度和湿度的敏感性，同时聚甲醛纤维还能进一步增强抗拉、抗压强度，保证水泥稳定碎石混合层的自养护效果，进而减少裂缝的出现。本发明能够将水泥稳定碎石层铺设时的联铺延迟时间由目前的4小时左右提高到10小时，克服了施工联铺时的时间局限性问题，保证了更长段落的连续施工。
