舊瀝青路面的再生方式主要有就地再生和廠拌再生兩類，前者又可分為就地熱再生和就地冷再生兩種方式。下面來講講相關的內容吧！

The regeneration methods of old asphalt pavement mainly include in-situ regeneration and plant mixing regeneration. The former can be divided into in-situ geothermal regeneration and in-situ cold regeneration. Let's talk about the relevant content!

就地冷再生施工工藝可對100mm500mm的破損路面及路基進行再施工，先銑削粉碎并收集舊路面材料，加入一定數(shù)量的石灰、水泥、乳化瀝青或泡沫瀝青等添加劑，攪拌后作為再生后的基層混合料使用。在此基層上再罩上一層磨耗層和適宜的表面處置作為面層，成型新的道路供使用。

The in-situ cold recycling construction process can be used for the reconstruction of damaged pavement and subgrade from 100mm to 500mm. First, milling, crushing and collecting the old pavement materials, adding a certain amount of lime, cement, emulsified asphalt or foam asphalt and other additives, and then mixing them as the recycled base course mixture. A wearing course and appropriate surface treatment shall be covered on the base course as the surface course to form a new road for use.

就地熱再生施工即用一臺綜合式再生重鋪機組，連續(xù)實現(xiàn)加熱、耙松、再生劑添加、加熱攪拌、攤鋪等工藝方案。該方案要求公路面層損傷較輕，而且聯(lián)結層和基礎層較完好。舊路面鋪層厚度大于50mm，且路面各種病害損壞深度小于50mm，舊瀝青針入度超過20（1/10mm），裂縫面積少于40%.就地熱再生特點是施工周期短，對交通干擾小，運輸量小，性好，但設備系統(tǒng)復雜，技術水平要求高，投資大。工藝柔性較差，不能利用現(xiàn)有的攤鋪設備和技術。

For geothermal regeneration construction, a comprehensive regeneration and resurfacing unit is used to continuously realize the process schemes of heating, scarifying, adding regenerant, heating mixing and paving. The scheme requires that the road surface layer is slightly damaged, and the connection layer and foundation layer are relatively intact. The pavement thickness of the old pavement is greater than 50mm, the damage depth of various pavement diseases is less than 50mm, the penetration of the old asphalt is more than 20 (1/10mm), and the crack area is less than 40% Geothermal regeneration is characterized by short construction period, small traffic disturbance, small transportation volume and good environmental protection. However, the equipment system is complex, the technical level is high and the investment is large. The process flexibility is poor, and the existing paving equipment and technology cannot be used.

此外冷再生機租賃廠家認為我們需要多了解相關的再生內容，比如說：

In addition, the leasing manufacturer of cold regeneration machine thinks that we need to know more about the relevant regeneration contents, such as:

廠拌再生則是將銑削的舊瀝青路面材料運送到攪拌廠（站），破碎、篩分處理后根據(jù)不同的舊材料以及翻新道路的要求，部分或全部采用舊材料，添加一定的瀝青或再生劑，加熱攪拌后運送到施工現(xiàn)場，攤鋪、碾壓。廠拌再生又分連續(xù)式和間歇式兩種。

Plant mixing and recycling is to transport the milled old asphalt pavement materials to the mixing plant (station). After crushing and screening, some or all of the old materials are used according to the requirements of different old materials and renovated roads. Certain asphalt or regenerant is added. After heating and mixing, the materials are transported to the construction site for paving and rolling. Plant mixing regeneration can be divided into continuous type and intermittent type.

廠拌再生過程、質量易于控制，可對不同的舊材料進行再生，適用于生產多種材料的再生，施工周期長，對交通干擾大，運輸費用也大，但可利用現(xiàn)有的施工設備，投資小，上項目比較容易。

The plant mixing regeneration process and quality are easy to control. It can regenerate different old materials. It is suitable for the regeneration of a variety of materials. The construction period is long, the traffic interference is large, and the transportation cost is large. However, the existing construction equipment can be used. The investment is small, and it is easy to start the project.
