（2）機(jī)械要求：工程施工過程通過再生機(jī)組來完成，再生機(jī)組包括：冷再生主機(jī)、水泥稀漿車、平地機(jī)、壓路機(jī)等。
(2) Mechanical requirements: the construction process of the project is completed by the regeneration unit, which includes: cold regeneration host, cement slurry truck, grader, roller, etc.
（3）人員要求：工程技術(shù)人員及機(jī)械操作人員應(yīng)經(jīng)過冷再生培訓(xùn)并經(jīng)過考核合格后方可上崗。
(3) Personnel requirements: Engineering and technical personnel and mechanical operators shall be trained in cold regeneration and qualified after examination.
（4）工程協(xié)調(diào)：作好施工總體計(jì)劃，采取不中斷交通半幅施工，作好施工期間交通疏導(dǎo)工作，準(zhǔn)備施工作業(yè)面的遮擋。
(4) Project coordination: make the overall construction plan, take half width construction without interrupting traffic, do a good job of traffic diversion during construction, and prepare for the shelter of the construction working surface.
2、施工方案
2. Construction scheme
A、一般規(guī)定
A. General provisions
（1）對原路面的路況進(jìn)行測量和調(diào)查，對高于原路面標(biāo)高5cm以上的地方用銑刨機(jī)進(jìn)行銑刨，并將銑刨后的舊路材料填于低于原路面標(biāo)高5cm以上的坑槽。
(1) Measure and investigate the road conditions of the original road surface, use a milling machine to mill the places 5cm above the original road surface elevation, and fill the milled old road materials in the pits 5cm above the original road surface elevation.
（2）對原路進(jìn)行加密挖驗(yàn)，將原瀝青路面用冷再生機(jī)取樣進(jìn)行標(biāo)準(zhǔn)擊實(shí)試驗(yàn)，確定合適的含水量與至大干密度。
(2) The original road shall be intensively excavated and tested, and the original asphalt pavement shall be sampled with a cold recycling machine for standard compaction test to determine the appropriate water content and maximum dry density.
（3）施工過程中根據(jù)再生料含水量情況及時(shí)調(diào)整再生機(jī)設(shè)定的用水量，密切注意天氣變化，避免在雨天進(jìn)行再生施工。
(3) During the construction process, adjust the water consumption set by the regenerator in time according to the water content of the recycled material, pay close attention to the weather changes, and avoid regeneration construction in rainy days.
B、試驗(yàn)段施工
B. Construction of test section
工程正式開工前，選取300m的道路作為試驗(yàn)路段，以確定現(xiàn)有道路的情況是否與設(shè)計(jì)要求相吻合，并在冷再生的級配、轉(zhuǎn)子的轉(zhuǎn)速及再生機(jī)械行走速度、壓實(shí)工藝幾個(gè)方面開展工作，為其余路段正式施工積累必要的數(shù)據(jù)。
Before the formal commencement of the project, 300m road is selected as the test section to determine whether the condition of the existing road is consistent with the design requirements, and work is carried out in the aspects of cold regeneration gradation, rotor speed, walking speed of regeneration machinery and compaction process, so as to accumulate necessary data for the formal construction of other sections.
（1）碾壓
(1) Rolling
當(dāng)平地機(jī)對再生層找平后，采用22T振動壓路機(jī)（前進(jìn)時(shí)靜壓，返回時(shí)振動）碾壓1遍，之后用自重26T振動壓路機(jī)進(jìn)行碾壓2～3遍，再用膠輪壓路機(jī)終壓1遍。碾壓過程中按規(guī)范要求嚴(yán)格控制平整度。
After leveling the regenerative layer with the grader, use 22T vibratory roller (static pressure when moving forward, vibration when returning) to roll for one time, then use the self weight 26t vibratory roller to roll for two to three times, and then use the rubber tyred roller to finally roll for one time. During rolling, the flatness shall be strictly controlled according to the specification requirements.
（2）養(yǎng)生
(2) Health preservation
碾壓檢測合格后及時(shí)采用塑料薄膜覆蓋養(yǎng)生，養(yǎng)生期內(nèi)中斷所有交通。因五一路比較繁忙，養(yǎng)生期為7d，養(yǎng)生期間冷再生基層表面始終保持濕潤，每天專人看管，確保再生層不因養(yǎng)生不當(dāng)產(chǎn)生損壞。
After the rolling test is qualified, the plastic film shall be used to cover the curing in time, and all traffic shall be interrupted during the curing period. Due to the busy May 1st Road, the curing period is 7 days. During the curing period, the surface of the cold recycled base course is always wet, and special personnel are assigned to take care of it every day to ensure that the recycled layer is not damaged due to improper curing.
（3）開放交通
(3) Open traffic
冷再生機(jī)施工后，等路面強(qiáng)度達(dá)到要求后，用空壓機(jī)吹凈浮灰，撒布透層油后，上面灑石屑，之后開放交通。
After the construction of the cold recycling machine, after the pavement strength meets the requirements, use the air compressor to blow away the floating ash, sprinkle the prime coat oil, sprinkle the stone chips on it, and then open the traffic.
