摘　　要：国内外对SBS物理改性沥青和化学改性沥青性能对比还未有深入研究。为此,对SBS物理改性沥青和化学改性沥青的性能采用常规与非常规(美国SHRP)的试验方法进行了较为系统地研究,进而对物理改性沥青和化学改性沥青的感温性能、高温稳定性、低温抗裂性以及抗老化性能进行了对比分析。同时,通过沥青混合料的试验,对两种改性沥青的路用性能进行比较,并且结合实际工程铺筑试验路对室内试验的结果进行验证。结果表明,SBS化学改性沥青的性能更为优越,是一种值得推广的路用材料。The comparison research was made on performance of SBS physical modified asphalt and SBS chemical modified asphalt. Normal and special （SHRP） test methods were adopted to study the performance of SBS physically modified asphalt and chemically modified asphalt systematically, including temperature susceptibility, high temperature stability, low temperature crack resistance and anti-aging property. Then the road use performance comparison of the asphalt mixtures was studied by the mixture test. Furthermore it validated the test results by building test road. It is concluded that the performance of SBS chemically modified asphalt is better and worthy to extend its road use.
