Rosphalt技术通过增加混合料的弹性恢复能力,防止永久变形的不断累积,达到避免车辙的目的。在对国外Rosphalt施工经验和使用情况的信息进行大量收集的基础上,在承唐高速公路工程中实施了一段Rosphalt桥面铺装试验路。这是该技术在国内的首次应用,是一次有意义的探索性工作,为该技术在国内的进一步推广积累了宝贵的经验。 Rosphalt technology by increasing the flexibility of the mixture resilience to prevent the permanent accumulation of cumulative deformation to achieve the purpose of avoiding rutting. Based on the extensive collection of information on the Rosphalt construction experience and usage abroad, a section of Rosphalt deck pavement test road was implemented in the Chengtang Expressway project. This is the first application of this technology in China. It is a meaningful exploratory work and has accumulated valuable experience in the further promotion of this technology in China.
