你知道什么是冷再生材料成形?

来源:http://www.sddhfjx.com/ 日期:2020-09-23
  关于冷再生总是会有很多种问题。今天小编来为大家介绍下什么是冷再生材料成形?
  There are always many problems with cold regeneration. Today, I'd like to introduce to you what is cold recycled material forming?
  冷再生材料的性质与传统道路材料不完全相同,因而对成形的要求也不完全相同。冷再生材料按再生剂大致可以区分为两类:无机再生剂和沥青再生剂,沥青再生时往往加入少量水泥以提高其抗水损坏能力。常用的无机再生剂是水泥,其他还有二灰、水泥粉煤灰等。
  The properties of cold recycled materials are not the same as those of traditional road materials, so the forming requirements are not completely the same. Cold recycled materials can be roughly divided into two categories: inorganic recycling agent and asphalt recycling agent. When asphalt is recycled, a small amount of cement is often added to improve its water damage resistance. The common inorganic regenerant is cement, and the others are lime fly ash and cement fly ash.

  无机稳定冷再生一般按照传统的半刚性材料进行成形和养生。常温下进行重型击实试验或者震动击实试验,在20°C或者25°C下养生7天。通过含水量-强度关系确定含水量。沥青稳定剂冷再生时的情况比较复杂,尚无统一方法。冷再生材料组成设计方法较为常见的方法是用击实法确定上佳液体量,用马歇尔稳定度、干劈裂强度、湿劈裂强度中的一个或几个达到优来确定沥青用量。
  Inorganic stable cold regeneration is generally formed and cured according to traditional semi-rigid materials. Heavy compaction test or vibration compaction test shall be carried out at room temperature, and the curing time shall be 7 days at 20 ° C or 25 ° C. The water content is determined by the relationship between water content and strength. The situation of cold regeneration of asphalt stabilizer is complex, and there is no unified method. The common method of cold recycling material composition design is to determine the best liquid content by compaction method, and determine the asphalt content by one or more of Marshall stability, dry splitting strength and wet splitting strength.
