摘　　要：应用辽化炼油厂的减压渣油作为原料,研制出符合GB/T15180 94标准的多个牌号重交通道路沥青。在实验中,将其中的AH 90与辽河AH 90、埃索AH 90、壳牌AH 90进行比较。考察它们的感温性能,结果表明,这种沥青具有良好的感温性能,高温稳定性,低温抗裂性以及较大的粘弹区间。能够满足我国北方地区的铺路沥青的要求。By using vacuum residue from Liaohua refinery as the raw material,several brand heavy paving asphalts have been produced, which meet GB/T15180-94 standard. We compared one of these brand heavy paving asphalts(AH-90) with Liaohe AH-90,Etta AH-90,Shell AH-90 in the experiment of this paper. As a result, we found that this brand paving asphalt has characteristics of good temperature susceptibility, good high-temperature stability , good low-temperature cracking resistance and relatively broad viscoelastic space.And so, it could meet requirement for paving in northern China.
