在四川省平昌县S304灵山镇元山镇段道路修复施工现场，由冷再生机、水泥撒布车、沥青罐车、摊铺机、压路机等组成的“公路再生列车”宛如巨龙缓缓驶过，原本车辙突显的沥青路面立即光洁平整、焕然一新。

　　At the road repair construction site from Lingshan Town to Yuanshan Town in S304, Pingchang County, Sichuan Province, a "highway recycling train" composed of cold recycling machines, cement spreaders, asphalt tankers, pavers, rollers, etc. slowly passed by like a giant dragon. The asphalt pavement, which was originally highlighted by ruts, immediately became clean, smooth, and refreshed.

　　“我们采用的是沥青路面‘冷再生’技术，对原沥青混凝土层进行泡沫沥青就地冷再生施工，再生好的混合料直接打入摊铺机中摊铺，然后碾压成型。”项目现场负责人彭不益说。

　　"We use the 'cold recycling' technology of asphalt pavement to carry out on-site cold recycling construction of foam asphalt on the original asphalt concrete layer. The recycled mixture is directly driven into the paver for paving, and then rolled into shape." Peng Buyi, the project site leader, said.

　　彭不益口中的“冷再生”技术是一种较为成熟的绿色公路维修改造技术，采用专用的再生设备，对沥青路面进行现场冷铣刨，破碎和筛分，掺入一定数量的新集料、再生结合料、活性填料、水，经常温拌和、摊铺、碾压等工序，一次性实现旧沥青路面再生的技术。相比于传统的铣刨重铺技术，该技术可节约30%的养护成本，将废旧路面材料再生循环应用于路面养护和维修，变废为宝，解决了废旧材料带来的环境污染问题，具有“提质增效、生态、缩短工期”的优势。

　　The "cold recycling" technology mentioned by Peng Buyi is a relatively mature green road maintenance and renovation technology. It uses specialized recycling equipment to perform on-site cold milling, crushing, and screening of asphalt pavement, adding a certain amount of new aggregates, recycled binders, active fillers, water, and regularly warm mixing, paving, rolling and other processes to achieve the technology of regenerating old asphalt pavement in one go. Compared to traditional milling and repaving techniques, this technology can save 30% of maintenance costs. It recycles and applies waste road materials for road maintenance and repair, turning waste into treasure and solving the environmental pollution caused by waste materials. It has the advantages of "improving quality and efficiency, ecological protection, and shortening construction period".

　　“我们可以充分发挥旧沥青混合料的‘剩余价值’，促进旧路面材料的循环利用，保护生态环境，减少资源浪费。”四川九正鼎盛城乡建设集团有限公司项目管理部夏金明介绍，S304灵山镇元山镇段总长度15，已完成道路改造85%，预计6月完工。

　　We can fully utilize the 'residual value' of old asphalt mixtures, promote the recycling of old pavement materials, protect the ecological environment, and reduce resource waste, "said Xia Jinming, Project Management Department of Sichuan Jiuzheng Dingsheng Urban and Rural Construction Group Co., Ltd. The S304 section from Lingshan Town to Yuanshan Town has a total length of 15 kilometers and has completed 85% of the road renovation. It is expected to be fully completed in June.

　　今年以来，平昌县不断加快公路提档升级改造，通过引进新材料、新技术、新工艺、新设备四新技术，持续在“次差等路、提升中等路、巩固优良等路”上下功夫，不断提升公路服务水平，提高群众交通出行的舒适性、性。

　　Since the beginning of this year, Pingchang County has continuously accelerated the upgrading and transformation of highways, by introducing new materials, new technologies, new processes, and new equipment, and continuously working on "eliminating inferior roads, improving medium roads, and consolidating excellent roads", continuously improving the level of highway services, and enhancing the comfort and safety of public transportation.
