水泥稳定碎石的特性及施工注意事项
来源：/ 日期：2022-08-03
大多数高速公路是典型的半刚性路面，由于具有振动小、噪声低等优点成为交通运输的重要方式。在这种半刚性路面中，水泥稳定碎石的生产对其性能有着重要的影响，下面来讲讲济南水泥稳定碎石的特性及施工注意事项吧。
Most expressways are typical semi-rigid pavement, which has become an important way of transportation due to its advantages of low vibration and low noise. In this semi-rigid pavement, the production of cement stabilized macadam has an important impact on its performance. Let's talk about the characteristics of Jinan cement stabilized macadam and construction precautions.
水泥稳定碎石的特性
Characteristics of cement stabilized macadam
1、强度高：在基层混合料灰剂量不超过6%的情况下，强度能达到6兆帕以上。
1. High strength: the strength can reach more than 6 MPa when the ash dosage of base course mixture is not more than 6%.
2、水稳性好：一旦钙化成型，便不怕水侵蚀。
2. Good water stability: once calcification is formed, it is not afraid of water erosion.
3、易操作：基层混合料易生产，拌和容易。灰剂量、含水量在级配一定的情况下，易控制，根据监测情况随时可以调整。
3. Easy operation: the base mixture is easy to produce and mix. The ash dosage and water content are easy to control when the gradation is certain, and can be adjusted at any time according to the monitoring situation.
4、抗疲劳能力强：因为强度高，比其它结构更稳定、持久。
4. Strong fatigue resistance: because of its high strength, it is more stable and durable than other structures.
5、远期成本低：使用寿命长，相应减少了建设成本。
5. Low long-term cost: long service life, which correspondingly reduces the construction cost.
6、半刚性：不同于水泥混凝土，不存在因收缩而产生裂纹。
6. Semi rigid: different from cement concrete, there is no crack due to shrinkage.
水泥稳定碎石施工需要注意的问题
Problems needing attention in cement stabilized macadam construction
1、严格控制混合料的灰剂量、含水量、级配的范围。
1. Strictly control the ash dosage, water content and grading range of the mixture.
2、调整好摊铺设备，在摊铺过程中严禁随意中止，以免混合料因长时间放置而影响碾压密实度和强度。
2. Adjust the paving equipment, and it is strictly forbidden to stop at will during the paving process, so as to prevent the mixture from affecting the compactness and strength of rolling due to long-term placement.
3、压路机司机须在混合料可塑状态下操作，即在水泥初凝时间前完成碾压工作。
3. The roller driver must operate in the plastic state of the mixture, that is, complete the rolling work before the initial setting time of cement.
4、安排专人跟随机械进行找平、处理基层平整度。
4. Arrange special personnel to follow the machinery to level and deal with the flatness of the base course.
5、碾压成型后要及时洒水养护，使基层混合料保持潮湿的状态。
5. After rolling and forming, watering and curing shall be carried out in time to keep the base mixture moist.
During construction, attention must be paid to controlling the range of ash dosage, water content and gradation of base course mixture, and improving the construction technology. Come to our website for more relevant precautions Consult and understand.
