冷再生機技術是在常溫下使用冷再生機械連續(xù)完成銑刨和破碎包括面層和部分基層在內(nèi)的舊路面結構層、添加再生材料、拌和、攤鋪、碾壓等作業(yè)過程.重新形成具有一 定承載能力的結構層的- -種工藝?,F(xiàn)在更為先進的是技術是瀝青路面就地熱再生。
Cold regeneration technology is a process of milling and crushing the old pavement structure layer including the surface layer and part of the base layer, adding recycled materials, mixing, paving, rolling and other operation processes under normal temperature by using cold recycling machinery, so as to re form the structural layer with certain bearing capacity. Now the more advanced technology is the hot recycling of asphalt pavement.
現(xiàn)場熱再生法就是在舊路面現(xiàn)場利用移動式的現(xiàn)場熱再生設備將舊瀝青路面加熱、耙送、經(jīng)過翻挖后加入再生劑、新瀝青、新骨料送進攪拌缸拌和 ,從而獲得優(yōu)良的再生瀝青混凝土,鋪筑成再生瀝青路面。此過程是- -一個動態(tài)連續(xù)的過程。在此過程中需根據(jù)路面材料配方的不同以及工程質量要求,進行配比設計,確定舊瀝青混合料中再生劑、新瀝青材料、新集料的比例。
The on-site hot recycling method is to use the mobile on-site thermal recycling equipment to heat the old asphalt pavement, rake it, add regenerant, new asphalt and new aggregate into the mixing tank after digging, so as to obtain excellent recycled asphalt concrete and pave the recycled asphalt pavement. This process is a dynamic and continuous process. In this process, the proportion design should be carried out according to the different pavement material formula and engineering quality requirements, and the proportion of recycled agent, new asphalt material and new aggregate in the old asphalt mixture should be determined.
現(xiàn)場熱再生方法的優(yōu)點:
The advantages of the on-site thermal regeneration method are as follows:
1.施工周期短。瀝青路面冷再生是列車對舊路面再生過后經(jīng)壓路機壓實后數(shù)小時就可恢復交通。
1. Short construction period. The cold recycling of asphalt pavement is that the traffic can be restored after the train regenerates the old road surface after being compacted by the roller for several hours.
2.施工成本低。生料無需再運輸?shù)焦潭▓龅?材料現(xiàn)場再生現(xiàn)場使用。
2. Low construction cost. Raw materials do not need to be transported to the fixed site, and the materials can be recycled on site.
3.設備轉場快、冷再生機租賃方便。
3. The equipment can be transferred quickly and the lease of cold regenerator is convenient.
