水泥穩定碎石是以級配碎石作骨料，采用一定數量的膠凝材料和足夠的灰漿體積填充骨料的空隙，按嵌擠原理攤鋪壓實。下面來講講濟南水泥穩定碎石的原材料與施工機械設備相關分析事項吧。
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：水泥的初凝時間不小于3h，終凝時間不小于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．集料規格及堆放：基層集料分為：0～4.75mm、4.75～13.2mm、13.2～31.5mm三檔，須分檔堆放、并設立材料報驗牌。
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.
所有原材料須是具有路面生產資質的料場生產，進料須按規定頻率檢查，防止所進材料發生不均勻、超規格、含泥量超標或其他指標不合格現象。
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.
其壓實度接近于密實度，強度主要靠碎石間的嵌擠鎖結原理，同時有足夠的灰漿體積來填充骨料的空隙。它的初期強度高，并且強度隨齡期而增加很快結成板體，因而具有較高的強度，抗滲度和抗凍性較好。
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.
水泥穩定碎石水泥用量一般為混合料3%～6%，7天的無側限抗壓強度可達5.0Mpa，較其他路基材料高。水泥穩定碎石成活后遇雨不泥濘，表面堅實，是路面的理想基層材料。
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)施工機械設備
（2） Construction machinery and equipment
1．拌合機：拌合設備須具有自動計量系統，且應計量準確(安裝好后經技術監督部門標定)、冷料倉須三倉以上，生產速度須能滿足施工進度要求。
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．攤鋪機：寬度在2.5m、長度在50m以上的路段須采用攤鋪機攤鋪。
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．壓路機：16t以上的壓路機。
3. Road roller: more than 16t.
4．灑水車：須滿足濕潤養護要求。
4. Sprinkler: it must meet the requirements of wet curing.
