水泥穩定碎石材料有哪些？
What are the cement stabilized macadam materials?
水泥穩定碎石材料主要由粒料和灰漿體積組成。粒料為級配碎石，灰漿體積包括水和膠凝材料，膠凝材料由水泥和混合材料組成。普通硅酸鹽水泥、礦渣硅酸鹽水泥和火山灰質硅酸鹽水泥均可，但應選用終凝時間較長的水泥。
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.
水泥穩定碎石的施工技術交底是什么？
What is the construction technical disclosure of cement stabilized macadam?
水泥穩定碎石一般適用于基層或底基層，厚度一般在15～22cm，為保證其質量，規范施工過程，特制定了水泥碎石的施工技術交底。本技術交底僅是對JTJ034-2000《公路路面基層施工技術規范》、圖紙、標書中《技術規范》、合同附件等中“水泥穩定土”一章的補充，請各單位一并執行。
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.
水泥穩定碎石作業完成24小時后才可以砌沿石嗎？
Can the edge stone be laid 24 hours after the completion of cement stabilized macadam operation?
一般情況下水泥穩定碎石作業完成24小時后才可以砌沿石。其與砌沿石的時間間隔也不宜太久，否則混合料形成板體后，板體堅硬，增加施工難度，敲鑿板體也極易破壞板體整體性。養生時間不少于7天，這期間禁止車輛通行，每日灑水車灑水養護2~4遍，保持濕潤。
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.
水穩碎石怎么養生？
How to keep the water stabilized macadam healthy?
濟南水泥穩定碎石一般封閉交通養生不少于7d，養生期間應保持表面濕潤，嚴禁重車交通行駛（養護用5000L灑水車允許通行）。養生一般在鋪筑成型后第二天開始，但必須確保在水泥終凝后再養生。灑水養生時，要注意邊緣上灑到位，灑水時均勻灑足，灑水次數隨氣候條件而定，一般為每天4～5次，用土工布覆蓋養生。
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.
