冷再生機(jī)的技術(shù)難題主要體現(xiàn)在哪？

冷再生機(jī)材料的混合均勻性和級(jí)配受冷再生機(jī)械結(jié)構(gòu)特性的影響。作為兩種核心類型的銑刨機(jī)和混合機(jī)，瀝青路面就地冷再生機(jī)和冷銑刨機(jī)發(fā)展同根同源技術(shù)與設(shè)備的應(yīng)用有著相同的技術(shù)基礎(chǔ)，但發(fā)展方向不同。

The mixing uniformity and gradation of rental materials of cold recycling machine are affected by the structural characteristics of cold recycling machine. As two core types of milling machine and mixer, asphalt pavement cold in place recycling machine and cold milling machine have the same development root, the application of technology and equipment has the same technical basis, but the development direction is different.

冷再生機(jī)是機(jī)器制造機(jī)的再生鼓，冷銑刨機(jī)的銑刨工作裝置是銑刨鼓。兩者都是由轉(zhuǎn)子的旋轉(zhuǎn)驅(qū)動(dòng)，以便切割路面移入-然而，原地冷循環(huán)更有可能再生筒上的銑床布置調(diào)整了再生瀝青混合料的粒徑，保證了再生料的完全混合。并假設(shè)二次銑削時(shí)，滾筒外緣與銑床端部之間所形成的空間的合理性足以保證再生材料的均勻性和分類。

The cold recycling machine is the recycling drum of the machine manufacturing machine, and the milling working device of the cold milling machine is the milling drum. Both of them are driven by the rotation of the rotor so that the road can be cut and moved in - however, the in-situ cold circulation is more likely, and the milling machine arrangement on the regeneration cylinder adjusts the particle size of the recycled asphalt mixture to ensure the complete mixing of the recycled asphalt mixture. It is assumed that the space formed between the outer edge of the roller and the end of the milling machine is reasonable enough to ensure the uniformity and classification of the recycled materials.
冷再生機(jī)租賃

冷再生機(jī)械瀝青坡道的再生利用大致可分為五種類型：廠拌熱再生、廠拌冷再生、就地?zé)嵩偕?、就地冷再生和全厚式就地冷再生。他們有自己的?yōu)勢(shì)，適合各種職業(yè)病合適的全厚度就地冷再生租賃是指連續(xù)完成銑磨、研磨、添加新材料、混合、分配、壓實(shí)新舊材料的綜合回收工藝，創(chuàng)建新基礎(chǔ)在一般來說，再生處理深度為15-750px，深為30-1250px。

The recycling of cold recycling mechanical asphalt ramp can be roughly divided into five types: plant mixed hot recycling, plant mixed cold recycling, on-site hot recycling, on-site cold recycling and full thickness on-site cold recycling. They have their own advantages, suitable for all kinds of occupational diseases, suitable full thickness cold in place recycling lease refers to the comprehensive recycling process of continuously completing milling, grinding, adding new materials, mixing, distributing and compacting new and old materials, creating a new foundation. Generally speaking, the depth of recycling treatment is 15-750px, and the depth is 30-1250px.

充分利用舊路面磚，降低了道路養(yǎng)護(hù)過程中路面材料的開挖、運(yùn)輸、垃圾處理、新材料采購等費(fèi)用，降低了冷再生機(jī)械租賃費(fèi)用減少。In一般來說，成本可以是20%-40%。厚度越小，可以降低的成本就越多重要的材料：水泥、水、少量新骨料、石灰(早期固體)等等采用水泥作為黏結(jié)劑是一種實(shí)用、廉價(jià)、快速且類似于半剛性基層的成熟技術(shù)。

Make full use of the old pavement brick, reduce the cost of road surface material excavation, transportation, garbage treatment, new material procurement in the process of road maintenance, and reduce the rental cost of cold recycling machinery. In general, the cost can be 20% - 40%. The smaller the thickness, the more important materials can be reduced: cement, water, a small amount of new aggregate, lime (early solid), etc. using cement as a binder is a practical, cheap, fast and mature technology similar to semi-rigid base.
