Abstract:

        Under certain process conditions , four brands colored paving asphalt conforming to GB/ T15180-94 standard w ere prepared by blending Liaohe asphalt and a variety of additives , blender and pigment .The road performance of 70# and 90 # colour paving asphalt was evaluated and their aging resistance was studied by viscosity method .The results show that these two brands colored asphalts whose penetration index ranged from -1.2 to +1 .0 have the characteristics of good temperature susceptibility , their equivalent softening point (T800), equivalent brittle point(T12)and viscoelastic space(T800 -T12)are similar or better than those of the cor responding standard of asphalt , they exhibit high temperature stability , good low -temperature cracking resistance , and the 70# colored paving asphalt with lower aging index than 90 # has better aging resistance.

摘要:         以辽河沥青(AH -70)为基质沥青, 在一定的工艺条件下, 加入各种添加剂, 调和剂和颜料, 采用调和法制备出了符合GB/ T15180 -94 的4 种牌号重交通道路标准的彩色道路沥青。对其中的70# 、90#两个牌号的彩色沥青路用性能进行了分析, 并用粘度法对其抗老化性能进行了评价。路用性能分析的结果表明, 所研制的两种彩色道路沥青针入度指数PI 在-1.2~ +1 .0 之间, 具备良好的感温性能;当量软化点T800 , 当量脆点T1 .2和粘弹区间(T800 - T1 .2)均相近或优于相应的沥青标准, 具有良好的高温稳定性和低温开裂性;70#彩色沥青老化指数低于90#彩色沥青, 抗老化性较好。
