The rational use of asphalt equipment to maximize its potential is the requirement of highway mechanized construction enterprises, and maintenance and repair are essential prerequisites for maximizing mechanical efficiency. In response to this situation, we have formulated and determined the maintenance content for each shift in mechanical management, and urged its implementation. At the end of each month, mandatory maintenance of asphalt equipment is carried out for 2-3 days, which eliminates many faults before they occur.

每天作業(yè)后應(yīng)該瀝青設(shè)備內(nèi)的殘余水泥混凝土，使拌刀磨損減小，延長了拌刀使用壽命;整機(jī)所有器件的塵土，對(duì)潤滑部位加注黃油，使整機(jī)潤滑部件的潤滑情況良好，減小了易損件的磨損，從而減少了因磨損而出現(xiàn)的機(jī)械故障;檢查各緊固件及易損件，發(fā)現(xiàn)問題及時(shí)予以解決，使有些故障排除在未出現(xiàn)以前，做到防患于未然;能堅(jiān)持每班保養(yǎng)，瀝青設(shè)備使用壽命平均可延長工作時(shí)間800h，拌刀可延長600h。

After daily operations, residual cement concrete should be removed from the asphalt equipment to reduce wear and prolong the service life of the mixing blade; Remove dust from all components of the entire machine, add grease to the lubrication parts, ensure good lubrication of the lubrication components of the machine, reduce wear on vulnerable parts, and thus reduce mechanical failures caused by wear; Check all fasteners and vulnerable parts, and promptly solve any problems found, so that some faults can be eliminated before they occur, so as to prevent problems before they occur; Being able to maintain every shift, the average service life of asphalt equipment can be extended by 800 hours, and the mixing blade can be extended by 600 hours.

1、冷再生出租技術(shù)具有適用性。早期路面診斷是非常必要的。水泥冷再生技術(shù)一般是原路面的碾壓、調(diào)平、碾壓、分層等施工技術(shù)。僅是淺層路面結(jié)構(gòu)的再生（不大于25cm），對(duì)于路面結(jié)構(gòu)下層的病害沒有修復(fù)作用。對(duì)于路面基層承載力不足，彎沉值過大等情況下需要恢復(fù)路面功能的深度處理，一個(gè)簡單的一層冷再生工藝不能起到徹底強(qiáng)化結(jié)構(gòu)層的作用。

1. The cold regeneration rental technology has applicability. Early road surface diagnosis is very necessary. Cement cold recycling technology generally refers to the construction techniques of rolling, leveling, rolling, and layering of the original road surface. The regeneration of only shallow pavement structures (not greater than 25cm) has no repair effect on the diseases in the lower layer of the pavement structure. For situations where the bearing capacity of the pavement base is insufficient and the deflection value is too large, a simple one layer cold regeneration process cannot fully strengthen the structural layer, which requires deep treatment to restore the pavement function.

2、水泥用量的確定將直接影響到再生層質(zhì)量。適當(dāng)?shù)乃鄤┝坎粌H可以避免因水泥劑量不足引起的乏力，還能減少過度的水泥劑量引起的基底應(yīng)力收縮裂縫，延長道路的使用壽命。

2. The determination of cement dosage will directly affect the quality of the recycled layer. An appropriate cement dosage can not only avoid fatigue caused by insufficient cement dosage, but also reduce base stress shrinkage cracks caused by excessive cement dosage, extending the service life of the road.

3、水泥的選擇是非常重要的。水泥的冷再生不需要使用任何水泥。它有嚴(yán)格的要求。水泥粘結(jié)劑的要求基本相同，青島冷再生機(jī)，水泥穩(wěn)定碎石。它需要延緩水泥初凝時(shí)間大于3h，終凝時(shí)間大于6小時(shí)的緩凝水泥。

3. The choice of cement is very important. The cold regeneration of cement does not require the use of any cement. It has strict requirements. The requirements for cement binder are basically the same, with Qingdao cold recycling machine and cement stabilized crushed stone. It requires delayed cement with an initial setting time greater than 3 hours and a final setting time greater than 6 hours.

4、施工用水的選擇。看似微不足道的因素，但可能是由于過多的雜質(zhì)或鹽離子過多的施工用水，造成質(zhì)量問題。

4. Selection of construction water. A seemingly insignificant factor, but it may be due to excessive impurities or salt ions in construction water, resulting in quality issues.

5、施工設(shè)備選型施工設(shè)備，施工設(shè)備其中包括再生機(jī)、壓路機(jī)等，因其不同的性能會(huì)影響到整個(gè)工程的質(zhì)量和效率，因此有必要選用操作智能，性能優(yōu)越的施工設(shè)備確保施工各環(huán)節(jié)的內(nèi)在質(zhì)量。

5. Construction equipment selection includes regeneration machines, road rollers, etc. Due to their different performance, which can affect the quality and efficiency of the entire project, it is necessary to choose construction equipment with intelligent operation and superior performance to ensure the internal quality of each construction link.

6、養(yǎng)生。有許多方法來保持健康：噴灑透層瀝青、灑水、覆蓋塑料薄膜等，養(yǎng)生期間斷絕或限制交通。

6. Health preservation. There are many ways to maintain health: spraying a layer of asphalt, watering, covering with plastic film, etc., and cutting off or restricting traffic during the health period.
