Abstract

Binders with good high-temperature performance and fuel resistance are urgently needed in paving construction to deal with the challenge of heavy traffic load. Hybrid binders of styrene-butadiene-styrene tri-block copolymer (SBS) modified asphalt and polyamide (PA) resin were prepared with various ratio. The influence of PA content on the performance of binders and mixtures was evaluated by rheological methods, dynamic stability, residual Marshall Stability ratio after immersing in kerosene, bending test and the indirect tensile (IDT) strength ratio after freeze–thaw cycle. The results showed that PA could improve the high-temperature performance and fuel resistance. The hybrid binder with 30% PA content has excellent high-temperature performance, fuel resistance and good workability at the same time.
