Application status of regeneration technology

沥青路面冷再生技术是目前养护工程的一项较广泛的应用性技术，它虽然在我国的应用时间不是很长（二十年左右），但基于该项技术的自身特点及符合我国的战略要求，近些年来，在我国的公路路面养护大、中修工程中达到了大量的使用。

Asphalt pavement cold recycling technology is a widely used technology in maintenance engineering at present. Although it has not been applied for a long time in China (about 20 years), based on its own characteristics and in line with the national strategic requirements of energy conservation and environmental protection, it has been widely used in large and medium-sized highway pavement maintenance projects in China in recent years.

从目前的工程应用程序来看，总体反映良好。本次我省的两个地方性规范的出台，对于冷再生技术的使用将产生良好的促进作用，也有利于进一步提升冷再生的工程质量。

From the current national engineering applications, the overall response is good. The introduction of the two local specifications in our province will not only promote the use of cold regeneration technology, but also further improve the engineering quality of cold regeneration.

由于冷再生工程应用的目的之一是基于旧路面材料的循环利用，且材料的利用率高（利用率在百分之90以上），故在具体的项目实施中受影响的因素较多（主要是原路面的结构及用料情况）。现徐州恒驰工程机械就路面冷再生机工程实施中的常见问题及处置对策提出一些建议，供大家在实际应用中参考。

As one of the purposes of the application of cold recycling engineering is based on the recycling of old pavement materials, and the utilization rate of materials is high (the utilization rate is more than 90%), there are many factors affected in the implementation of specific projects (mainly the structure and material consumption of the original pavement). At present, Xuzhou hengchi construction machinery puts forward some suggestions on the common problems and Disposal Countermeasures in the implementation of pavement cold recycling machine project for your reference in practical application.

水泥就地冷再生

In situ cold recycling of cement

1、设计方面的建议：

1. Design suggestions:

1）、冷再生层的设计厚度：应综合考虑旧路面的结构层情况确定水泥就地冷再生的设计厚度，避免产生再生层施工后存在超薄夹层的现象。

1) Design thickness of cold recycling layer: the design thickness of cement in-situ cold recycling should be determined by comprehensively considering the structural layer of the old pavement, so as to avoid the phenomenon of ultra-thin interlayer after the construction of recycling layer.

2）、旧路面沥青层厚度占再生层厚度的比例：在重交通的情况下，考虑再生层的强度要求等因素，建议旧沥青层厚度比例不应大于百分之30。如旧路面沥青层厚度较大，应设计先铣刨旧沥青层（部分或全部），再进行水泥冷再生施工。铣刨的沥青材料可作厂拌冷（热）再生进行利用。

2) The proportion of the thickness of the old asphalt layer in the thickness of the recycled layer: in the case of heavy traffic, considering the strength requirements of the recycled layer and other factors, it is recommended that the thickness proportion of the old asphalt layer should not be greater than 30%. If the thickness of the asphalt layer of the old pavement is large, the old asphalt layer (part or all) shall be milled first, and then the cement cold recycling construction shall be carried out. Recycled materials for cold milling.

2、施工方面的问题：

2. Construction problems:

1）、铣刨拌和的均匀性问题：应以再生混合料拌合均匀及不产生离析为目标，控制调整再生机的工作行驶速度和转子速度（破碎梁开度）等。

1) Uniformity of milling and mixing: Aiming at uniform mixing and no segregation of recycled mixture, control and adjust the working driving speed and rotor speed (opening of crushing beam) of the regenerator.

2）、影响再生层的强度的主要因素：水泥用量及撒布均匀性，拌合用水量的控制，再生层的压实及封闭养生等。

2) Main factors affecting the strength of the recycled layer: cement dosage and distribution uniformity, control of mixing water consumption, compaction and sealing curing of the recycled layer, etc.

3）、再生层可能产生纵向裂缝问题：再生机纵向搭接处的用水量控制，每作业段长度选择的合理性等。

3) Longitudinal cracks may occur in the regeneration layer: water consumption control at the longitudinal lap joint of the regeneration machine, rationality of length selection of each operation section, etc.
