水泥稳定碎石的原材料与施工机械设备分析
来源：/ 日期：2022-10-10
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。下面来讲讲济南水泥稳定碎石的原材料与施工机械设备相关分析事项吧。
The cement stabilized crushed stone is made of graded crushed stone as aggregate, and a certain amount of cementitious material and sufficient mortar volume are used to fill the gap of aggregate, which is paved and compacted according to the principle of embedding. Now let's talk about the analysis of raw materials and construction machinery and equipment of Jinan cement stabilized macadam.
(一)原材料
（1） Raw materials
1．水泥：水泥的初凝时间不小于3h，终凝时间不小于6h。
1. Cement: the initial setting time of cement shall not be less than 3h, and the final setting time shall not be less than 6h.
2．集料规格及堆放：基层集料分为：0～4.75mm、4.75～13.2mm、13.2～31.5mm三档，须分档堆放、并设立材料报验牌。
2. Aggregate specification and stacking: The base aggregate is divided into three grades: 0~4.75mm, 4.75~13.2mm and 13.2~31.5mm, which must be stacked in different grades, and a material inspection board shall be set up.
所有原材料须是具有路面生产资质的料场生产，进料须按规定频率检查，防止所进材料发生不均匀、超规格、含泥量超标或其他指标不合格现象。
All raw materials must be produced in the stock yard with pavement production qualification, and the incoming materials must be inspected according to the specified frequency to prevent the incoming materials from being uneven, exceeding the specification, exceeding the mud content or other indicators from being unqualified.
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。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。
The compactness is close to the compactness, and the strength is mainly based on the principle of interlocking between the crushed stones. At the same time, there is enough mortar volume to fill the gap of the aggregate. Its initial strength is high, and the strength increases with age and quickly forms a plate, so it has higher strength, better impermeability and frost resistance.
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。
The cement consumption of cement stabilized crushed stone is generally 3%~6% of the mixture. The unconfined compressive strength in 7 days can reach 5.0Mpa, which is higher than other subgrade materials. Cement stabilized macadam is not muddy in rain after survival, and its surface is solid. It is an ideal base material for pavement.
(二)施工机械设备
（2） Construction machinery and equipment
1．拌合机：拌合设备须具有自动计量系统，且应计量准确(安装好后经技术监督部门标定)、冷料仓须三仓以上，生产速度须能满足施工进度要求。
1. Mixer: the mixing equipment must have an automatic metering system, and the metering should be accurate (calibrated by the technical supervision department after installation). The cold silo must have more than three warehouses, and the production speed must meet the requirements of the construction progress.
2．摊铺机：宽度在2.5m、长度在50m以上的路段须采用摊铺机摊铺。
2. Paver: the road section with a width of 2.5m and a length of more than 50m must be paved with a paver.
3．压路机：16t以上的压路机。
3. Road roller: more than 16t.
4．洒水车：须满足湿润养护要求。
4. Sprinkler: it must meet the requirements of wet curing.
