就地冷再生進(jìn)行突出整形注意六點
來源：http://kqj188.com/ 日期：2023-02-27 發(fā)布人：
就地冷再生是指充分利用現(xiàn)有瀝青道路舊鋪層材料，根據(jù)對混合料性能的要求，加入部分新骨料，并按設(shè)計加入一定量的水泥，在自然環(huán)境溫度下連續(xù)地完成材料的銑刨、破碎、拌合、攤鋪及壓實成型，從而修筑出具有所需性能質(zhì)量的新基層的作業(yè)過程。就地冷再生進(jìn)行突出整形注意什么呢?冷再生機(jī)租賃廠家為您講解：
Local cold recycling refers to the operation process of making full use of the existing asphalt pavement materials, adding some new aggregates according to the requirements for the performance of the mixture, and adding a certain amount of cement according to the design, and continuously completing the milling, crushing, mixing, paving and compaction of the materials under the natural environment temperature, so as to build a new base with the required performance quality. What should we pay attention to when rolling and shaping with local cold regeneration? The cold regeneration machine rental manufacturer explains to you:
（1）根據(jù)路寬、壓路機(jī)的輪寬和輪距的不同，制訂突出方案，應(yīng)使各部分突出到的次數(shù)盡量相同，路面的兩側(cè)應(yīng)多壓2~3遍。
(1) According to the difference of road width, wheel width and wheel width of the roller, the rolling scheme shall be formulated, so that the rolling times of each part shall be the same as far as possible, and the two sides of the pavement shall be rolled more than 2-3 times.
（2）在冷再生機(jī)后應(yīng)配備一臺大噸位單鋼輪振動壓路機(jī)進(jìn)行初壓。初壓時先讓壓路機(jī)緊跟再生機(jī)后面進(jìn)行一遍靜壓，靜壓后采用強(qiáng)振（高幅低頻）進(jìn)行壓實，壓實遍數(shù)應(yīng)足以保證再生層底部2/3厚度范圍內(nèi)的壓實度達(dá)到規(guī)定要求。
(2) After cold reinvigoration, a large-tonnage single-drum vibratory roller shall be equipped for initial compaction. During the initial compaction, let the roller immediately follow the regenerator to carry out a static compaction, and then use strong vibration (high amplitude and low frequency) for compaction. The number of compaction times should be sufficient to ensure that the compactness within the range of 2/3 thickness of the bottom of the regeneration layer meets the specified requirements.
（3）在完成一個作業(yè)段的冷再生和初壓后，應(yīng)立即用平地機(jī)整形。在直線段，平地機(jī)由兩側(cè)向路中心進(jìn)行刮平；在平曲線段，平地機(jī)由內(nèi)側(cè)向外側(cè)進(jìn)行刮平。
(3) After completing the cold regeneration and initial compaction of a working section, the grader shall be used for shaping immediately. In the straight section, the grader scrapes from both sides to the center of the road; In the flat curve section, the grader scrapes from the inside to the outside.
（4）在整形前，如果冷再生材料表面水分散失比較嚴(yán)重，可以先灑水后用平地機(jī)整形。
(4) Before shaping, if the water loss on the surface of the cold recycled material is serious, it can be sprinkled first and then reshaped with a grader.
（5）整形后，應(yīng)立即用單鋼輪振動壓路機(jī)以弱振（低幅高頻）進(jìn)行復(fù)壓。直線和不設(shè)很高的平曲線段，由路肩向路中心碾時，每次應(yīng)重疊1/2輪寬，壓完路面全寬時即為一遍。一般需突出4~6遍。壓路機(jī)的突出速度，頭兩遍以采用1.5~1.7km/h為宜，以后宜采用2.0~2.5km/h。
(5) After shaping, the single-drum vibratory roller shall be used for re-pressing with weak vibration (low amplitude and high frequency) immediately. The straight line and the flat curve section with no very high height shall be overlapped by 1/2 wheel width each time when rolling from the shoulder to the center of the road, and it is one time when rolling the full width of the road. Generally, it needs to be rolled 4~6 times. The rolling speed of the roller should be 1.5~1.7km/h for the first two passes, and 2.0~2.5km/h for the next two passes.
（6）后用膠輪壓路機(jī)進(jìn)行終壓，必要時可灑水突出。
(6) After that, the rubber wheel roller shall be used for final compaction, and water can be sprayed for rolling if necessary.
此外利用現(xiàn)有瀝青道路舊鋪層材料（面層與基層），根據(jù)對混合料性能的要求，并按設(shè)計要求加入不小于5%的水泥，在自然環(huán)境溫度下連續(xù)地完成材料的銑刨、破碎、拌和、攤鋪及壓實成型，從而修筑出具有所需性能質(zhì)量的新基層的作業(yè)過程。
In addition, using the existing asphalt pavement materials (surface course and base course), according to the requirements for the performance of the mixture, and adding no less than 5% of cement according to the design requirements, the operation process of milling, crushing, mixing, paving and compaction of the materials under the natural environment temperature is continuously completed, and then the new base course with the required performance quality is constructed.
