摘要
为确定抗紫外线改性剂的品种和剂量,以提高沥青路面的路用性能。本文通过沥青紫外线老化试验进行对比分析得出:炭黑、抗氧剂及丁苯橡胶均有改善效果;综合分析,在青海强紫外线地区可首选丁苯橡胶作为沥青抗紫外线的改性剂。
To determine the species and dose of UV resistance modifiers to improve the asphalt pavement road performance,asphalt UV aging tests were done.Carbon black,antioxidants and styrene-butadiene rubber could improve the effect.The styrene-butadiene rubber modifier as asphalt UV-resistant is recommended in the strong ultraviolet region of Qinghai.
