摘要
在混合料配合比设计的基础上,对比研究SBS改性沥青混合料及TLA+SBS复合改性沥青混合料的路用性能,结果表明TLA+SBS复合改性沥青混合料在抗水损害、高温性能及低温性能方面都具有更优良的效果。结合工程实践,介绍了TLA+SBS复合改性沥青混合料在市政道路路面维修工程中的应用情况。
On the basis of mix proportion design of asphalt mixture, the pavement performances of SBS modified asphalt mixture and TLA+SBS composite modified asphalt mixture are compared and studied. The results show that the TLA+SBS composite modified asphalt mixture has better effect on resistance to water damage, high temperature performance and low temperature performance. Combined with engineering practice, the application of TLA+SBS composite modified asphalt mixture in the maintenance of municipal road pavement is introduced.
