濟(jì)南水穩(wěn)料就是水泥穩(wěn)定碎石的簡(jiǎn)稱，水泥穩(wěn)定碎石是以級(jí)配碎石作骨料，采用一定數(shù)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(shí)。其壓實(shí)度接近于密實(shí)度，強(qiáng)度主要靠碎石間的嵌擠鎖結(jié)原理，同時(shí)有足夠的灰漿體積來(lái)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.

它的初期強(qiáng)度高，并且強(qiáng)度隨齡期而增加很快結(jié)成板體，因而具有較高的強(qiáng)度，抗?jié)B度和抗凍性較好。水泥穩(wěn)定碎石水泥用量一般為混合料3%~6%，7天的無(wú)側(cè)限抗壓強(qiáng)度可達(dá)5.0Mpa，較其他路基材料高。水泥穩(wěn)定碎石成活后遇雨不泥濘，表面堅(jiān)實(shí)，是高級(jí)路面的理想基層材料。

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.

水穩(wěn)路面基層施工工藝可以概括為“一重點(diǎn)、二環(huán)節(jié)、三區(qū)段、八流程”。即：抓住“配合比”這一個(gè)重點(diǎn)，對(duì)“拌和場(chǎng)和施工現(xiàn)場(chǎng)”的二個(gè)環(huán)節(jié)、施工現(xiàn)場(chǎng)的“攤鋪區(qū)、壓實(shí)區(qū)和整形區(qū)”三個(gè)區(qū)段和對(duì)“施工準(zhǔn)備→施工放樣→拌和→運(yùn)輸→攤鋪整平→碾壓→整形封面→灑水養(yǎng)生和交通管制”八個(gè)流程流程進(jìn)行全面有效的控制。

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".

濟(jì)南水穩(wěn)料

相關(guān)規(guī)定：

Relevant regulations:

根據(jù)規(guī)定，水泥穩(wěn)定碎石均屬中粒土，由于水穩(wěn)中含有水泥等膠凝材料因而要求整個(gè)施工過(guò)程要在水泥終凝前完成，并且一次達(dá)到質(zhì)量標(biāo)準(zhǔn)，否則不易修整。因而施工中要求加強(qiáng)施工組織設(shè)計(jì)和計(jì)劃治理，增加現(xiàn)場(chǎng)施工人員的緊迫感和責(zé)任感，加快施工進(jìn)度，加大機(jī)械化施工程度，提高機(jī)械效率。水穩(wěn)的施工方法也符合現(xiàn)代化大規(guī)模機(jī)械化發(fā)展的方向。因而水穩(wěn)在市政工程中的應(yīng)用會(huì)得到很快推廣。

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.
