冷再生机租赁简介

Introduction to Cold Recycling Machine Rental

　　道路冷再生机租赁是在常温下使用冷再生机械（以路星LZS2400型就地冷再生机为例）连续完成铣刨和破碎旧路面结构层(包括面层和部分基层)、添加再生材料、拌和、摊铺等作业过程，碾压成型后的摊铺层可作为低等级公路的基层或面层及高等级公路的底基层或基层，属于道路养护维修范畴。它主要解决沥青路面上基层破损的问题。具体讲，道路冷再生是指充分利用现有沥青道路旧铺层材料（面层与基层）必要时加入部分新骨料，并按比例加入一 定量的添加剂（水泥、石灰、粉煤灰等）在自然环境温度下就地连续地完成材料的铣刨、破碎、拌和、摊铺及压实成型，从而修筑出具有所需性能质量的新基层的作业过程。

Road cold recycling machine rental refers to the use of cold recycling machinery (taking the Luxing LZS2400 on-site cold recycling machine as an example) at room temperature to continuously complete the milling and crushing of old pavement structural layers (including surface layers and some base layers), adding recycled materials, mixing, paving and other operations. The rolled paving layer can be used as the base or surface layer of low-grade highways and the subgrade or base layer of high-grade highways, which belongs to the scope of road maintenance and repair. It mainly solves the problem of base damage on asphalt pavement. Specifically, road cold recycling refers to the process of fully utilizing existing asphalt pavement materials (surface layer and base layer), adding some new aggregates when necessary, and adding a certain amount of additives (cement, lime, fly ash, etc.) in proportion to continuously mill, crush, mix, spread, and compact the materials on site at natural ambient temperatures, in order to construct a new base layer with the required performance quality.

　　冷再生机租赁不仅适用于高等级公路的维修与改造，也适用于一般道路及乡间公路的维修与改造。此技术在欧美等国家已得到了较为普遍的应用，并常常作为路面维修的首 选方案，随我国98年引进第 一台就地冷再生机后，近几年来，就地冷再生技术在我国受到了业内人士普遍的关注与认同，推广普及速度很快，例如辽宁、吉林及河北等地区已经应用相当普遍，并且取得了良好的效果。

Cold recycling machine leasing is not only suitable for the maintenance and renovation of high-grade highways, but also for the maintenance and renovation of general roads and rural roads. This technology has been widely applied in countries such as Europe and America, and is often used as the preferred solution for road maintenance. With the introduction of the first on-site cold recycling machine in China in 1998, in recent years, on-site cold recycling technology has received widespread attention and recognition from industry insiders in China, and its promotion and popularization speed is very fast. For example, it has been widely applied in regions such as Liaoning, Jilin, and Hebei, and has achieved good results.

　　冷再生机租赁的主要施工机具为集破碎与拌和为一体的冷再生机。冷再生机的核心是装有大量专用刀头的铣刨和拌和转子。转子向上旋转铣刨原路面材料，冷再生机向前行进时，转子转动，同时水通过软管从再生机连接的水车中运送过来，并在再生机的拌和仓中喷洒。水的输送量通过微处理器控制的泵送系统精确控制。铣刨转子将水与铣刨料充分拌和，并达到需要的含水量，从而达到混合料的大压实度。

The main construction equipment for leasing cold recycling machines is a cold recycling machine that integrates crushing and mixing. The core of a cold recycling machine is a milling and mixing rotor equipped with a large number of specialized cutting heads. The rotor rotates upwards to mill the raw road surface material, and when the cold recycling machine moves forward, the rotor rotates. At the same time, water is transported from the water truck connected to the recycling machine through a hose and sprayed in the mixing bin of the recycling machine. The water delivery volume is precisely controlled by a microprocessor controlled pumping system. The milling rotor thoroughly mixes water with the milling material to achieve the required moisture content, thereby achieving high compaction of the mixture.

　　粉状稳定剂，如水泥,白灰，需按设计添加量事先撒布在再生机前的路面上，再生机将粉状稳定剂与再生料和水一次性拌和。

Powdered stabilizers, such as cement and white ash, need to be spread on the road surface in front of the recycling machine according to the designed addition amount. The recycling machine will mix the powdered stabilizer with recycled materials and water at once.
