摘要:

为探究高黏度改性沥青SMA-10混合料在道路超薄罩面养护技术上的应用效果，通过室内试验并结合实际工程，主要从沥青混合料的配比设计、性能检验、现场施工等方面展开。结果表明，高黏度改性沥青作用于SMA-10沥青混合料展现出优异的道路使用性能，且工程效果显著，可为道路超薄罩面加铺养护材料提供参考。

Abstract:

In order to explore the application of high viscosity modified asphalt effect on the SMA-10 asphalt mixture in road ultra-thin cover maintenance technology was tracked by the indoor test and combined with the actual project, which is mainly from the proportion of asphalt mixture design, performance inspection, field construction and other aspects. The results indicates that asphalt mixture with high viscosity modified asphalt shows a good road performance and engineering application, which can provide the reference for pavement maintenance material of ultra-thin road surface.
