摘　　要：依据美国ASTM D5710-95和英国BSI BS 3690对Trinidad湖沥青(TLA)的评价标准,以及中华人民共和国行业标准JTG F40-2004《公路改性沥青路面施工技术规范》对改性沥青混合料和SBS类(I类)改性沥青储存稳定性的技术要求,对比同样试验条件下TLA改性沥青的特性,评价了煤与FCC油浆共处理所得重质产物对道路石油沥青的改性作用。结果表明,在400℃、10 MPa H2压力条件下所得的重质产物(CSA)对试验用90#基质沥青的改性作用与TLA的改性作用相似,满足上述各标准的指标要求;CSA改性沥青的混合料具有较高的极限拉伸应变值,即具有较好的弯曲性能,显示了更加优良的低温抗裂性能。The heavy product produced by co-processing of coal and FCC slurry was studied as high grade paving asphalt modifier. Trinidad lake asphalt （TLA） was used as comparison material. Specifications of ASTM D5710-95,BSI BS 3690 and JTG F40-2004 were used as the standard for evaluation. The heavy product tested was produced by co-processing of Yanzhou coal with FCC slurry at temperature of 400℃ under about 10 MPa hydrogen pressure and named as CSA. The results showed that the properties of CSA-modified-asphalt （with mass ratio of CSA to base asphalt of 1/4） met the specifications of the standards and were similar to that of TLA-modified-asphalt. The both modified asphalts satisfied the storage stability requirement. The limited tensile stain of CSA-modified-asphalt concrete was much higher than that of TLA-modified-asphalt concrete, showing its supreme low-temperature stability.
