Vibration-pressing-free self-curing cement stabilized macadam mixture as well as preparation method and application thereof
The invention discloses a vibration-pressing-free self-curing cement stabilized macadam mixture as well as a preparation method and application thereof, belonging to the technical field of road construction. The mixture comprises the following raw materials: aggregate, cement, a water reducing agent, an expanding agent, water-absorbent resin and water. The use amount of the cement is 4.5-6% of the mass of the aggregate; the use amount of the water reducing agent is 0.36-0.6% of the mass of the aggregate; the use amount of the expanding agent is 0.29-0.48% of the mass of the aggregate; the use amount of the water-absorbent resin is 1.1-1.5% of the mass of the aggregate; and the use amount of the water is 7.6-8.5% of the mass of the aggregate. The cement stabilized macadam mixture can form cement stabilized macadam under the condition of no vibration compaction and self-curing, and the problems that traditional cement stabilized macadam needs vibration compaction to cause great harm to surrounding buildings and cracks are easily generated due to insufficient watering curing are solved. The preparation method is simple in process and easy to operate. When the anti-cracking agent is used for forming vibration-pressing-free self-curing cement stabilized macadam, and macadam with good anti-cracking performance can be obtained.
本发明公开了一种免振压自养护水泥稳定碎石混合料及其制备方法与应用，属于道路施工技术领域。其原料包括集料、水泥、减水剂、膨胀剂、吸水树脂及水；水泥的用量为集料质量的4.5‑6％，减水剂的用量为集料质量的0.36‑0.6％，膨胀剂的用量为集料质量的0.29‑0.48％，吸水树脂的用量为集料质量的1.1‑1.5％，水的用量为集料质量的7.6‑8.5％。该水泥稳定碎石混合料可在免振压及自养护的条件下形成水泥稳定碎石，避免了传统水泥稳定碎石因需要振动压实导致对周围建筑危害大以及洒水养生不足容易产生裂缝的问题。其制备方法简单，易操作。将其用于形成免振压自养护水泥稳定碎石，能获得具有良好的抗裂性能的碎石。
