阻燃沥青及沥青混合料研究

Study of Flame Retardant Asphalt and Asphalt Mixture

阐述了常用沥青阻燃剂的分类及其特点,并分析了阻燃剂的阻燃机理。针对阻燃沥青的应用现状,提出了目前研究中存在的问题及发展方向。通过对比阻燃矿粉、阻燃纤维与其它矿粉、纤维的阻燃效果,总结了其优点与局限性。大孔隙沥青混凝土(OGFC)用于隧道阻燃路面取得了一定的成效,也存在一些问题,通过列举几种环保阻燃沥青混合料,对阻燃沥青混合料形成一个思路补充。

The article sets forth the classification and characteristics of the common asphalt flame retardant,analyzes the flame retardant mechanism,and puts forward the problems existing in the present study and its development direction according to the application status of flame retardant asphalt.By the comparison of the flame retardant effects of various mineral powders and fibers,the article sums up the advantages and limitations of flame retardant asphalt.The open-graded asphalt friction course(OGFC) has some effect to use for the flame retardant pavement of tunnel,but there are some problems.The article replenishes the idea of flame retardant asphalt mixture by several cases of environmental protective flame retardant asphalt mixture.
