在公路大中修工程中，旧路材料的废弃与运输一直是困扰行业的痛点。250S冷再生机的出现，将“铣刨、破碎、拌和、摊铺”四道工序合为一体，在路面现场完成对旧料的就地再生利用。这台由维特根打造的WR2500S机型，以500kW的强劲动力，正在改写路面改造的环保账与经济账。

The disposal and transportation of old road materials have always been a pain point for the industry in highway major and medium maintenance projects. The emergence of the 250S cold recycling machine integrates the four processes of milling, crushing, mixing, and paving, and completes the on-site recycling of old materials on the road surface. This WR2500S model, built by Wirtgen, is rewriting the environmental and economic accounts of road surface renovation with its powerful 500kW power.

一、使用范围：适用多类路面再生工程

1、 Scope of use: Suitable for various types of pavement regeneration projects

250S冷再生机的适用场景覆盖了多种路面结构类型。在水泥稳定碎石基层的返工修复中，当摊铺后的水稳层出现厚度不足、取芯失败等质量缺陷时，无需挖除重铺，通过加铺水泥并就地冷再生即可快速修复。在沥青路面翻修中，它可配合乳化沥青或泡沫沥青，对旧沥青面层和部分基层进行全深式再生，形成新的承载结构层。

The applicable scenarios of the 250S cold recycling machine cover various types of road surface structures. In the rework and repair of cement stabilized crushed stone base, when quality defects such as insufficient thickness and failed coring occur in the water stable layer after paving, there is no need to excavate and re pave it. It can be quickly repaired by adding cement and cold recycling on site. In asphalt pavement renovation, it can cooperate with emulsified asphalt or foam asphalt to fully regenerate the old asphalt surface course and part of the base course to form a new bearing structure layer.

该设备在不同等级公路均有广泛应用。在县乡道路、国省干线中，它处理二灰碎石和水稳基层的再生作业表现优异；在高等级公路上，使用水泥添加剂的全深式就地冷再生混合料的7天无侧限抗压强度和劈裂强度均可满足规范对基层的要求。此外，它还可用于公路路基的石灰、水泥土层的拌和，相当于一个移动的灰土拌和站。

This device is widely used on highways of different grades. In county and township roads, as well as national and provincial trunk lines, it has shown excellent performance in the regeneration of fly ash stabilized crushed stone and water stable base layers; On high-grade highways, the 7-day unconfined compressive strength and splitting strength of the fully deep in-situ cold recycled mixture using cement additives can meet the requirements of the specifications for the base layer. In addition, it can also be used for mixing lime and cement soil layers in highway subgrades, equivalent to a mobile lime soil mixing station.

二、核心优势：出色、节能、环保三位一体

2、 Core advantages: Efficient, energy-saving, and environmentally friendly in one

250S冷再生机的核心价值在于其出色的出色性。配备道依茨TCD2015V08发动机，额定功率500kW，为重型作业提供充沛动力支持。非常大铣拌宽度可达3048mm，非常大铣拌深度达500mm，单次通过即可完成大范围路面再生，大幅缩短施工周期，减少对交通的干扰。

The core value of the 250S cold regeneration machine lies in its ultimate efficiency. Equipped with a Deutz TCD2015V08 engine with a rated power of 500kW, it provides ample power support for heavy-duty operations. The maximum milling and mixing width can reach 3048mm, and the maximum milling and mixing depth can reach 500mm. A single pass can complete large-scale road regeneration, greatly reducing the construction period and minimizing interference with traffic.

在成本与环保效益层面，冷再生的优势在于“就地取材”。传统工艺需要将旧路面材料铣刨运输至拌合站，再运回现场摊铺，运输成本高且资源浪费严重。冷再生机现场完成全部工序，旧料100%利用，消除了往返运输的费用和碳排放。在返工修复场景中，这一工艺能以出色低成本、出色快速度解决水稳层取芯失败等突发问题，具有显著的经济效益和社会效益。

In terms of cost and environmental benefits, the advantage of cold recycling lies in the use of locally sourced materials. Traditional techniques require milling and transporting old pavement materials to the mixing station, and then transporting them back to the site for paving, which incurs high transportation costs and serious resource waste. The cold recycling machine completes all processes on site, with 100% utilization of old materials, eliminating the cost of round-trip transportation and carbon emissions. In the scenario of rework and repair, this process can solve sudden problems such as water stable layer core failure at extremely low cost and extremely fast speed, and has significant economic and social benefits.

在适应性与灵活性方面，250S冷再生机可适应多种粘结剂——乳化沥青、泡沫沥青、水泥、石灰均可灵活选用，根据不同路况和设计要求调整配比。其可回收处理整个道路结构层，无论是浅层路面还是深度加固，大多能通过单层或多层再生工艺实现。

In terms of adaptability and flexibility, 250S cold recycling machine can adapt to a variety of binders - emulsified asphalt, foam asphalt, cement, lime can be flexibly selected, and the proportion can be adjusted according to different road conditions and design requirements. It can recycle the entire road structure layer, whether it is shallow pavement or deep reinforcement, and can be achieved through single-layer or multi-layer recycling processes.
