水泥稳定碎石材料有哪些？
What are the cement stabilized macadam materials?
水泥稳定碎石材料主要由粒料和灰浆体积组成。粒料为级配碎石，灰浆体积包括水和胶凝材料，胶凝材料由水泥和混合材料组成。普通硅酸盐水泥、矿渣硅酸盐水泥和火山灰质硅酸盐水泥均可，但应选用终凝时间较长的水泥。
Cement stabilized macadam material is mainly composed of granular material and mortar volume. The granular material is graded crushed stone, and the mortar volume includes water and cementitious materials, which are composed of cement and mixed materials. Ordinary portland cement, slag Portland cement and pozzolanic Portland cement can be used, but the cement with long final setting time shall be selected.
水泥稳定碎石的施工技术交底是什么？
What is the construction technical disclosure of cement stabilized macadam?
水泥稳定碎石一般适用于基层或底基层，厚度一般在15～22cm，为保证其质量，规范施工过程，特制定了水泥碎石的施工技术交底。本技术交底仅是对JTJ034-2000《公路路面基层施工技术规范》、图纸、标书中《技术规范》、合同附件等中“水泥稳定土”一章的补充，请各单位一并执行。
Cement stabilized macadam is generally applicable to the base or subbase, with a thickness of 15 ~ 22cm. In order to ensure its quality and standardize the construction process, the construction technical disclosure of cement stabilized macadam is specially formulated. This technical disclosure is only a supplement to the chapter "cement stabilized soil" in jtj034-2000 technical specifications for construction of highway pavement base, technical specifications in drawings and bidding documents, contract appendices, etc., which shall be implemented by all units.
水泥稳定碎石作业完成24小时后才可以砌沿石吗？
Can the edge stone be laid 24 hours after the completion of cement stabilized macadam operation?
一般情况下水泥稳定碎石作业完成24小时后才可以砌沿石。其与砌沿石的时间间隔也不宜太久，否则混合料形成板体后，板体坚硬，增加施工难度，敲凿板体也极易破坏板体整体性。养生时间不少于7天，这期间禁止车辆通行，每日洒水车洒水养护2~4遍，保持湿润。
Generally, the edge stone can be laid 24 hours after the completion of cement stabilized macadam operation. The time interval between the slab and the masonry edge stone should not be too long, otherwise, after the mixture forms the slab, the slab will be hard, which will increase the construction difficulty, and the integrity of the slab will be easily damaged by chiseling the slab. The curing time shall not be less than 7 days. During this period, vehicles are not allowed to pass. The watering cart shall be used for curing 2~4 times a day to keep it moist.
水稳碎石怎么养生？
How to keep the water stabilized macadam healthy?
济南水泥稳定碎石一般封闭交通养生不少于7d，养生期间应保持表面湿润，严禁重车交通行驶（养护用5000L洒水车允许通行）。养生一般在铺筑成型后第二天开始，但必须确保在水泥终凝后再养生。洒水养生时，要注意边缘上洒到位，洒水时均匀洒足，洒水次数随气候条件而定，一般为每天4～5次，用土工布覆盖养生。
Jinan cement stabilized macadam is generally cured in closed traffic for not less than 7d. During the curing period, the surface shall be kept wet. Heavy vehicle traffic is strictly prohibited (5000L sprinkler is allowed for maintenance). Generally, the curing shall be started on the second day after the paving and forming, but it must be ensured that the curing can be carried out after the final setting of the cement. When sprinkling water for curing, pay attention to sprinkling water on the edge in place. When sprinkling water, sprinkle it evenly and fully. The frequency of sprinkling water depends on the climatic conditions, generally 4-5 times a day. Cover it with Geotextile for curing.
