摘要
随着环保意识的增强,沥青的环保性能成为关注重点,为了进一步推进环保净味沥青技术的发展,综述了沥青烟气主动抑制技术的发展现状及研究进展。首先根据应用原理不同,将沥青烟气主动抑烟技术分为降温施工法、气味遮盖法、除味法和源头改进法4种;其次对各类方法的特点和存在的问题进行了详细评述,认为除味法实施方式简单且效果较为明显,是今后的主要发展方向;最后建议在发展烟气抑制技术进行的同时,加快进行环保性能评价方法研究。
With the enhancement of public awareness of environmental protection,the environmental protection performance of asphalt has become the focus of technicians.In order to promote the development of green asphalt technology,the development status and research progress of active suppression technology of asphalt fume are summarized.Firstly,according to different application principles,the active fume suppression technology of asphalt is divided into four kinds:cooling construction method,odor covering method,odor removal method and source improvement method.Then,the characteristics and existing problems of various methods are reviewed in detail.It is considered that the implementation of odor removal method is simple and effective,which is the main development direction in the future.Finally,it is recommended to accelerate the research of environmental performance evaluation method while developing the fume suppression technology.
