| 摘 要： | 氢氧化铝可作为阻燃剂在沥青路面中使用，加入氢氧化铝阻燃剂可以使沥青变得黏稠，随着阻燃剂掺量的加大，沥青针入度、延度变小，软化点逐渐变大。氢氧化铝的加入可以提高沥青混合料的高温抗永久变形能力，有利于减少路面车辙，而对水稳定性没有明显影响。

| Abstract: | Aluminum hydroxide can be used as a flame retardant in the asphalt pavement. Adding alumi- num hydroxide flame retardant can make asphalt sticky. With the increase of flame retardant agent dosage, as- phalt penetration and ductility becomes smaller, softening point becomes larger. Aluminum hydroxide addition can improve the resistance to permanent deformation of asphalt mixture at high temperature, is conducive to re- ducing the rut, and has no obvious influence on the water stability. |
