一台高达3米多、770匹马力、有着两对超大轮胎的“大块头”，轰鸣地驶过龟裂的水泥路面。所到之处，铣刨转子如同精准外科手术刀，将深达32厘米的坚硬水泥板块瞬间“瓦解”成0—10厘米的碎石。这就是近日记者在徐州锐马重工机械有限公司（以下简称“锐马重工”）看到的一幕。

　　A "big guy" over 3 meters tall, with 770 horsepower and two pairs of oversized tires roared over the cracked cement road. Wherever it goes, the milling rotor is like a precision surgical knife, instantly "disintegrating" the hard cement slab up to 32 centimeters deep into 0-10 centimeters of gravel. This is what the reporter saw recently at Xuzhou Ruima Heavy Industry Machinery Co., Ltd. (hereinafter referred to as "Ruima Heavy Industry").

　　“路面冷再生机是基于眼前对原有水泥砼路面进行合理再生（循环）利用趋势应运而生的，是在冷态（常温）下利用近两百个铣刨刀齿对水泥路面铣刨破碎，并通过添加稳定剂，拌和、摊铺成型，是日常基建里路面再生常用的高性能设备。”公司总经理孙文忠带着记者边参观边介绍。路面冷再生机在与压路机、运输车等车辆的协同合作下，一天能让2000—8000平方米的旧路“脱胎换骨”。由于路面冷再生机体积大、赛道精细，“所以行业整体产量较少，我们年产量在40台左右。

　　The road surface cold recycling machine was born based on the trend of reasonable recycling of existing cement concrete road surfaces. It uses nearly 200 milling cutter teeth to mill and crush cement road surfaces in a cold state (at room temperature), and mixes and spreads them into shapes by adding stabilizers. It is a high-performance equipment commonly used for road surface recycling in daily infrastructure construction. "Sun Wenzhong, the general manager of the company, introduced it to reporters while visiting. The road surface cold recycling machine, in collaboration with rollers, transport vehicles, and other vehicles, can "transform" old roads of 2000-8000 square meters in a day. Due to the large volume and precise track of the road surface cold recycling machine, the overall output of the industry is relatively low, and our annual output is around 40 units.

　　锐马重工的路面“魔术”，绝不仅仅是“破旧”，更在于“立新”。孙文忠告诉记者，破碎后的碎石并非废弃，而是珍贵的资源。“我们认识到破碎水泥的再生价值，主动研发工艺，将破碎后的水泥板就地转化为30厘米厚的大厚度水稳基层。这项工艺能一次性形成坚实路基，不仅工期大幅缩短、几乎不抬高原有路面标高，还实现了原路面材料100%的循环利用，真正做到‘吃干榨净’‘零废弃’排放，取得了经济效益与环保效益的双赢。

　　The 'magic' of Ruima Heavy Industry's road surface is not just about being 'old', but also about being 'new'. Sun Wenzhong told reporters that the broken gravel is not abandoned, but a precious resource. We recognize the regenerative value of crushed cement and actively develop a process to transform the crushed cement board into a thick water stable base layer of 30 centimeters on site. This process can form a solid roadbed in one go, not only greatly reducing the construction period and almost not raising the elevation of the road surface, but also achieving 100% recycling of raw road materials, truly achieving 'dry and clean' and 'zero waste' emissions, achieving a win-win situation of economic and environmental benefits.
