对于施工方和业主而言，成本永远是考量要素。冷再生技术的吸引力在于其显著的经济效益。相比传统的“铣刨+重铺”工艺，冷再生技术通常能节约30%到40%的综合成本。

For both the construction contractor and the owner, cost is always the primary consideration. The greatest appeal of cold recycling technology lies in its significant economic benefits. Compared to the traditional "milling + resurfacing" process, cold recycling technology typically saves 30% to 40% of the overall cost.

这笔账主要体现在三个方面：一是材料成本，冷再生工艺能将旧路面材料100%就地回收利用，极大减少了对新石料、沥青等原材料的采购需求；二是运输成本，由于是就地作业，省去了大量旧料外运和新料进场的车辆运输费用；三是人工与时间成本，冷再生机施工效率极高，能大幅缩短工期，从而降低了人工开支和因封路带来的社会间接成本。对于预算有限但需要大面积修复路网的工程来说，冷再生无疑是性价比的选择。

This cost is primarily reflected in three aspects: Firstly, material cost. The cold recycling process enables 100% on-site recycling and utilization of old pavement materials, significantly reducing the procurement demand for new raw materials such as aggregates and asphalt. Secondly, transportation cost. Since it is an on-site operation, it eliminates a substantial amount of vehicle transportation costs for transporting old materials out and bringing new materials in. Thirdly, labor and time cost. The cold recycling machine operates with extremely high efficiency, significantly shortening the construction period, thereby reducing labor expenses and the indirect social costs caused by road closures. For projects with limited budgets but requiring large-scale road network repairs, cold recycling is undoubtedly the most cost-effective choice.
