摘　　要：道路表面功能和使用性能易衰减,可采用罩面进行恢复,但何种类型混合料效果最佳值得研究。采用SMA-13、AC-13、OGFC-13、Nova Chip(C型)4种类型的混合料对比研究其高温稳定性、低温抗裂性、水稳定性和抗滑性能,结果表明:Nova Chip(C型)沥青混合料与SBS改性沥青混合料路用性能最好,特别是Nova Chip不但高温稳定性最好,而且低温抗裂性和水稳定性也较其他混合料出色,构造深度仅次于OGFC,建议旧路薄层罩面优先选择Nova Chip混合料。Degradation of road surface functions and service performance could use overcoat for recovering, but which type of mixture is best is worthy of study. Four types of mixtures which are namely SMA-13, AC-13, OGFC-13 and Nova Chip （C） are studied on their high temperature stability, lowtemperature cracking resistance, water stability and skid resistance. Results show that the pavement performance of Nova Chip （C） asphalt mixture when mixing with SBS modified asphalt is the best. To be highlighted, besides of the Nova Chip has high temperature stability, its low temperature crack resistance and water stability are also superior than those of the others mixings, and its structural depth is only after OGFC. Nova Chip mixture is recommended for thin overcoat on the old road.
