摘要:

道路沥青在施工过程中产生的沥青烟无组织排放不仅会影响周围空气质量,还会对施工人员及周围居民造成健康隐患。为减少沥青烟污染,研究并使用较多的方法有工艺减排以及低排放沥青两种。工艺减排是采用一定的技术手段降低沥青体系的黏度,从而降低沥青混合料的拌合温度,以减少沥青烟排放。本文对温拌沥青技术研究进行了部分阐述,详细综述了研究较多的低排放沥青,即添加抑烟剂(阻燃剂、吸附剂、聚合物及一些新型材料等)通过物理或化学的方法将沥青烟气中的小分子加以固定,从而减少排放量。但单独使用某一抑烟剂会导致部分路用性能的下降,采用复配的方法从而克服这一缺点。本文对环保型沥青的研究及进展进行了总结并展望。

Abstract:

During the construction of road asphalt, the disorganized emission of asphalt smoke will lead to the decline of the surrounding air quality, and affect the health of the construction personnel and the surrounding residents. In order to reduce asphalt smoke pollution, there are two methods: process emission reduction and low-emission asphalt research.Process emission reduction is to reduce the viscosity of asphalt system by certain technical means, so as to reduce the mixing temperature of asphalt mixture, and reduce asphalt smoke emission. In this paper, the research on warm-mix asphalt technology is partially described. Extensive research on low emission asphalt, which is adding smoke inhibitor (flame retardant, adsorbent, polymer and some new materials, etc.) to fix the small molecules in asphalt flue gas by physical or chemical methods to reduce emissions, is reviewed in detail. However, the use of a single smoke suppressant will lead to the decline of some road performance, so the compound method can overcome this shortcoming. In this paper, the research progress of environmentally asphalt is summarized and prospected.

Key words: asphalt smoke, smoke suppressant, environmental protection, taste purification
