Recycling machine/stabilized soil mixer
Materials can be crushed and/or mixed on-site. They are mainly used for two special operations: cold recycling of road surfaces and soil stabilization. These operations may occur at different construction sites, including roads, airport runways, and parking lots.
Cold road regeneration
Cold pavement recycling is a road maintenance technology that provides the base material for rebuilding roads by crushing pavement materials on-site.
路面冷再生相对于其它养护技术而言有很多优势。工作在现场完成并且相对较快；每天工作效率一般为双车道道路一英里(1.6 km) 。道路或街道可保持交通开放，而且可以重新使用铣削下的旧材料做为新道路基层。与其它的路面养护技术的初始成本比较时，冷再生通常可以大幅度地节约时间和。
Cold pavement regeneration has many advantages compared to other maintenance technologies. The work is completed on-site and relatively fast; The daily work efficiency is generally one mile (1.6 km) on a two-lane road. Roads or streets can be kept open to traffic and old milled materials can be reused as the new road base. When compared to the initial cost of other road maintenance technologies, cold regeneration can usually significantly save time and money.
Soil stabilization is a road construction technique that utilizes mechanical or chemical methods to improve soil properties. Soil stabilization technology is also useful for chemical remediation purposes, by adding chemicals to materials to neutralize hazardous substances.
A stabilized soil mixer is an ideal machine for mixing additives (dry chemicals, emulsifiers, or stones) with roadbed paving materials, which can form a uniform, high-grade, and stable mixture of materials, thereby contributing to the excellent stability of the roadbed. They can also be used to screen stable material sizes according to the specified maximum particle size, or to fill soil to reduce the moisture content of the material before compaction.
Caterpillar's cold recycling machine crushes the asphalt layer and mixes it with the roadbed to stabilize the aging road surface. The cold recycling machine can add asphalt emulsion or other adhesives during crushing or independent mixing.
