工程中的水稳料有什么事项需了解？
来源：/ 日期：2023-03-06
济南水稳料就是水泥稳定碎石的简称，水泥稳定碎石是以级配碎石作骨料，采用一定数量的胶凝材料和足够的灰浆体积填充骨料的空隙，按嵌挤原理摊铺压实。其压实度接近于密实度，强度主要靠碎石间的嵌挤锁结原理，同时有足够的灰浆体积来填充骨料的空隙。
Jinan water stabilized material is the abbreviation of cement stabilized macadam. Cement stabilized macadam uses graded macadam as aggregate, uses a certain amount of cementitious material and sufficient mortar volume to fill the gap of aggregate, and paves and compacts according to the principle of inlaying. Its compactness is close to compactness, and its strength mainly depends on the principle of inlaying and locking between crushed stones, and there is enough mortar volume to fill the gap of aggregate.
它的初期强度高，并且强度随龄期而增加很快结成板体，因而具有较高的强度，抗渗度和抗冻性较好。水泥稳定碎石水泥用量一般为混合料3%~6%，7天的无侧限抗压强度可达5.0Mpa，较其他路基材料高。水泥稳定碎石成活后遇雨不泥泞，表面坚实，是路面的理想基层材料。
Its initial strength is high, and its strength increases with age and quickly forms a plate, so it has high strength, good permeability and frost resistance. The cement content of cement stabilized macadam is generally 3%~6% of the mixture, and the unconfined compressive strength in 7 days can reach 5.0Mpa, which is higher than other subgrade materials. The cement stabilized macadam is not muddy in the rain and has a solid surface after survival. It is an ideal base material for high-grade pavement.
水稳路面基层施工工艺可以概括为“一、二环节、三区段、八流程”。即：抓住“配合比”这一个，对“拌和场和施工现场”的二个环节、施工现场的“摊铺区、压实区和整形区”三个区段和对“施工准备→施工放样→拌和→运输→摊铺整平→碾压→整形封面→洒水养生和交通管制”八个流程流程进行有效的控制。
The construction process of water stabilized pavement base can be summarized as "one key point, two links, three sections and eight processes". That is, to grasp the key point of "mix ratio", to comprehensively and effectively control the two links of "mixing plant and construction site", the three sections of "paving area, compaction area and shaping area" of the construction site, and the eight processes of "construction preparation → construction setting out → mixing → transportation → paving and leveling → rolling → shaping cover → watering curing and traffic control".
相关规定：
Relevant regulations:
根据规定，水泥稳定碎石均属中粒土，由于水稳中含有水泥等胶凝材料因而要求整个施工过程要在水泥终凝前完成，并且一次达到质量标准，否则不易修整。因而施工中要求加强施工组织设计和计划治理，增加现场施工人员的紧迫感和责任感，加快施工进度，加大机械化施工程度，提高机械效率。水稳的施工方法也符合现代化大规模机械化发展的方向。因而水稳在市政工程中的应用会得到很快推广。
According to the regulations, cement-stabilized macadam belongs to medium-grained soil. Since cement and other cementitious materials are included in the water stability, the whole construction process is required to be completed before the final setting of cement and meet the quality standard at one time, otherwise it is not easy to repair. Therefore, during the construction, it is required to strengthen the construction organization design and plan management, increase the sense of urgency and responsibility of the on-site construction personnel, speed up the construction progress, increase the degree of mechanized construction, and improve the mechanical efficiency. The construction method of water stabilization is also in line with the development direction of modern large-scale mechanization. Therefore, the application of water stabilization in municipal engineering will be rapidly promoted.
