冷再生工藝有其適用性，先期需進(jìn)行路面診斷。該工藝只是對于≯25cm的淺層路面結(jié)構(gòu)的再生利用，對路面結(jié)構(gòu)下層的病害沒有修復(fù)作用，對于路面基層承載力不足，彎沉值過大等情況需要進(jìn)行深層處理以恢復(fù)路面的使用功能，簡單的一層冷再生工藝不能起到徹底強化結(jié)構(gòu)層的作用。下面冷再生機租賃廠家為您講解下相關(guān)工藝信息：
The cold regeneration process has its applicability and requires road surface diagnosis in the early stage. This process is only for the regeneration and utilization of shallow pavement structures with a thickness of not more than 25cm, and has no repair effect on the diseases in the lower layer of the pavement structure. For situations such as insufficient bearing capacity of the pavement base and excessive deflection value, deep treatment is needed to restore the functionality of the pavement. A simple one layer cold regeneration process cannot fully strengthen the structural layer. Below, the manufacturer of the cold regeneration machine rental will explain the relevant process information to you:
（1）原材料試驗。施工前，用再生機在原舊路面上銑刨有代表性的樣品，了解實際結(jié)構(gòu)層厚度和材料類型，為試驗室配合比設(shè)計提供樣品。選取的銑刨料樣品應(yīng)進(jìn)行下列試驗：級配試驗、塑性指數(shù)、擊實試驗、含水量。
(1) Raw material testing. Before construction, use a recycling machine to mill representative samples on the original and old road surface, understand the actual structural layer thickness and material type, and provide samples for the laboratory mix design. The selected milling material samples should undergo the following tests: gradation test, plasticity index, compaction test, and moisture content.
施工段落每5公里檢測路面銑刨料的級配、擊實試驗、隨時檢測含水量。根據(jù)擊實試驗所取得的大干密度校核車的水泥撒鋪量。冷再生底基層壓實度檢測采用200mm罐砂桶檢測，依據(jù)擊實所得的干密度控制現(xiàn)場壓實度。
During the construction section, the grading and compaction test of the road surface milling material should be tested every 5 kilometers, and the water content should be checked at any time. Check the cement spreading amount of the truck based on the high dry density obtained from the compaction test. The compaction degree of the cold recycled subbase layer is tested using a 200mm sand bucket, and the on-site compaction degree is controlled based on the dry density obtained from compaction.
（2）水泥用量的控制。適宜的水泥劑量不僅可以避免因水泥劑量不足而導(dǎo)致的強度不足，而且可以減少因水泥劑量過大而造成的基層應(yīng)力收縮裂縫現(xiàn)象，延長道路的壽命。
(2) Control of cement dosage. A suitable cement dosage can not only avoid insufficient strength caused by insufficient cement dosage, but also reduce the phenomenon of stress shrinkage cracks in the base layer caused by excessive cement dosage, and extend the service life of the road.
根據(jù)厚度、寬度、水泥劑量計算每平方米撒鋪水泥用量：1m×1m×厚度×干密度×0.97×水泥劑量;
Calculate the amount of cement spread per square meter based on thickness, width, and cement dosage: 1m × 1m × thickness × Dry density × zero point nine seven × Cement dosage;
（3）標(biāo)定粉料撒鋪車的撒鋪量，確定撒鋪車的撒鋪系數(shù);
(3) Calibrate the spreading amount of the powder spreading vehicle and determine the spreading coefficient of the spreading vehicle;
（4）每2公里檢測撒鋪車每平方的撒鋪用量;
(4) Detect the spreading amount per square meter of the spreading vehicle every 2 kilometers;
（5）試驗室做標(biāo)準(zhǔn)曲線，滴定法控制水泥劑量。
(5) The laboratory makes standard curves and controls the cement dosage using titration method.
