冷再生機(jī)對(duì)原路面進(jìn)行哪些施工操作
來源：http://www.kqj188.com/ 日期：2022-12-14 發(fā)布人：
冷再生機(jī)對(duì)原路面進(jìn)行舊路材料和水泥充分加水拌和，有關(guān)試驗(yàn)人員應(yīng)立即現(xiàn)場檢測含水量，使冷再生的含水量比佳含水量高出1%～2%，以滿足水泥水化作用的需要，同時(shí)彌補(bǔ)突出過程中含水量的損失。下面冷再生機(jī)租賃廠家就來講講冷再生機(jī)對(duì)原路面進(jìn)行哪些施工操作。
The cold recycling machine shall fully add water to mix the old road materials and cement on the original pavement. The relevant test personnel shall immediately detect the water content on the site to make the water content of the cold recycling machine 1%~2% higher than the good one, so as to meet the needs of cement hydration, and make up for the loss of water content during rolling. The following is about the construction operation of the cold recycling machine on the original pavement.
拌和時(shí)冷再生機(jī)行走速度控制在6m/min。水車在冷再生機(jī)前面用水帶與之相連并同步進(jìn)行，為冷再生機(jī)加水。水車與冷再生機(jī)連接拆卸與安裝選在每一施工段起點(diǎn)進(jìn)行。
The traveling speed of the intercooling regenerator shall be controlled at 6m/min. The waterwheel is connected to and synchronized with the water belt in front of the cold regeneration machine to add water to the cold regeneration machine. The connection, removal and installation of the waterwheel and the cold regenerator shall be carried out at the starting point of each construction section.
冷再生混合料拌和均勻后，用壓路機(jī)排壓一遍，速度控制在3km/h。排壓過程中若發(fā)現(xiàn)含水量不均勻或不平處，應(yīng)將補(bǔ)料連同其下層混合料一起翻松10em，刮平后再壓實(shí)，經(jīng)過排壓之后，用平地機(jī)按設(shè)計(jì)高程整平至符合設(shè)計(jì)標(biāo)準(zhǔn)。
After the cold recycled mixture is evenly mixed, it shall be discharged and compacted once with a roller, and the speed shall be controlled at 3km/h. If uneven or uneven water content is found in the process of pressure relief, the supplementary material and its lower layer mixture shall be scarified for 10em, and then compacted after scraping. After pressure relief, the land leveler shall be used to level according to the design elevation to meet the design standard.
（1）突出組合：突出遵循先輕后重，先慢后快的原則，先用YZ14振動(dòng)壓路機(jī)穩(wěn)壓一遍，壓路機(jī)壓四到五遍，三輪壓路機(jī)靜壓兩遍，20t胎壓路機(jī)壓兩遍。突出時(shí)注意錯(cuò)軸寬度，并由路邊向路中心依次突出，終壓之后；冷再生層應(yīng)平整光滑，表面有水漿滲出，注意終壓完成時(shí)間不能超過水泥終凝時(shí)間。突出完成后灌砂法測定壓實(shí)度，保證密實(shí)度滿足設(shè)計(jì)要求。
(1) Rolling combination: the principle of "light first, heavy second, slow first, fast second" shall be followed for rolling. First, YZ14 vibratory roller shall be used to stabilize the pressure once, the roller shall be used for four to five times, the three wheel roller shall be used for static pressure twice, and the 20t tire roller shall be used for rolling twice. When rolling, pay attention to the width of the staggered axis, and roll from the roadside to the road center in turn, after the final rolling; The cold regeneration layer shall be flat and smooth, with water oozing from the surface. It shall be noted that the completion time of final compaction shall not exceed the final setting time of cement. After compaction, measure the compactness by sand filling method to ensure that the compactness meets the design requirements.
（2）施工時(shí)間控制：試驗(yàn)段施工過程中冷再生機(jī)平均速變?yōu)?m/min。施工過程中應(yīng)盡量減少無故停機(jī)時(shí)間和刮平時(shí)間，確?？傮w上每一段落施工時(shí)間在4.5小時(shí)以內(nèi)。
(2) Construction time control: the average speed of the cold regenerator is changed to 6m/min during the construction of the test section. During the construction process, it is necessary to minimize the time of unscheduled shutdown and leveling, and ensure that the construction time of each section is within 4.5 hours in general.
（3）養(yǎng)生：突出成形四小時(shí)后（視氣溫情況），可以用潮濕的帆布和其他合適的潮濕材料覆蓋。在整個(gè)養(yǎng)生期間，都應(yīng)保持覆蓋材料處于潮濕狀態(tài)。也可用水車在冷再生層上直接淋水養(yǎng)護(hù)。在七天內(nèi)禁止放行交通，始終保持表面濕潤。
(3) Curing: Four hours after rolling forming (depending on the temperature), wet canvas and other suitable wet materials can be used for covering. During the whole curing period, the covering materials shall be kept in a damp state. Water truck can also be used to directly spray water on the cold regeneration layer for curing. It is prohibited to release traffic within seven days, and the surface shall always be kept wet.
