濟(jì)南水泥穩(wěn)定碎石施工采用什么施工工藝呢？實(shí)際上會(huì)采用商品水穩(wěn)（預(yù)拌），用機(jī)械攤鋪、壓路機(jī)碾壓的施工工藝。下面詳細(xì)講下：
What construction technology is used in Jinan cement stabilized macadam construction? In fact, the construction technology of commercial water stabilization (premix), mechanical paving and roller rolling will be adopted. Let's talk about it in detail:
1、原材料基本要求普通硅酸鹽水泥、礦渣硅酸鹽水泥、火山灰質(zhì)硅酸鹽水泥都可以用于水泥穩(wěn)定碎石路面基層施工，禁止使用快硬水泥、早強(qiáng)水泥以及其它受外界影響而變質(zhì)的水泥。
1. Basic requirements for raw materials Ordinary Portland cement, slag Portland cement and pozzolanic Portland cement can be used for the construction of cement stabilized macadam pavement base. Fast hardening cement, early strength cement and other cement deteriorated by external influence are prohibited.
路面基層宜采用強(qiáng)度等級(jí)較低的水泥；水泥各齡期強(qiáng)度、安定性等應(yīng)達(dá)到相應(yīng)指標(biāo)要求；要求水泥初凝時(shí)間3小時(shí)以上、終凝時(shí)間不小于6小時(shí)。
Cement with lower strength grade should be used for pavement base course; The strength and stability of cement at each age shall meet the corresponding index requirements; The initial setting time of cement shall be more than 3 hours and the final setting time shall not be less than 6 hours.
2、水泥穩(wěn)定碎石施工前準(zhǔn)備
2. Preparation before construction of cement stabilized macadam
①本工程水泥穩(wěn)定碎石基層的下承層為水泥穩(wěn)定土基層，水泥穩(wěn)定碎石攤鋪須在水泥穩(wěn)定土達(dá)到規(guī)定的強(qiáng)度、平整度、拱度等基礎(chǔ)上，經(jīng)驗(yàn)收后，才能進(jìn)行攤鋪。
① The lower bearing layer of the cement stabilized macadam base course of this project is the cement stabilized soil base course. The cement stabilized macadam can only be paved after the cement stabilized soil reaches the specified strength, flatness, camber, etc.
②恢復(fù)中線。每10～15m設(shè)置一樁，用指示樁標(biāo)出攤鋪寬度。
② Restore the center line. One pile shall be set every 10~15m, and the paving width shall be marked with an indicator pile.
③進(jìn)行水平測量。在每一斷面上設(shè)置3個(gè)指示樁（即中心樁、左側(cè)邊樁和右側(cè)邊樁），用明顯標(biāo)記標(biāo)出水泥穩(wěn)定碎石基層松鋪厚度和設(shè)計(jì)高程。
③ Carry out level measurement. Set 3 indicator piles (i.e. center pile, left side pile and right side pile) on each section, and mark the loose paving thickness and design elevation of cement stabilized macadam base with obvious marks.
④培肩。為減少水泥穩(wěn)定碎石混合料在碾壓過程中的側(cè)向位移，保證水泥穩(wěn)定碎石壓實(shí)度，采取培肩措施，培肩上口寬50cm下口寬70cm，高度不小于水泥穩(wěn)定碎石壓實(shí)厚度。為保證雨天排水，可每隔5～10m開挖臨時(shí)排水溝。
④ Shoulder training. In order to reduce the lateral displacement of cement stabilized macadam mixture during rolling and ensure the compactness of cement stabilized macadam, shoulder training measures are taken. The width of the upper opening of the shoulder is 50cm and the width of the lower opening is 70cm. The height is not less than the compacted thickness of cement stabilized macadam. To ensure drainage in rainy days, temporary drainage ditches can be excavated every 5-10m.
⑤施工前須詳細(xì)計(jì)劃安排，盡量減少橫向接縫，避免縱向接縫。
⑤ Before construction, detailed planning and arrangement shall be made to minimize transverse joints and avoid longitudinal joints.
