超薄磨耗层处理公路沥青路面病害应用探析

Application of Ultrathin Wear Layer in Treatment of Diseases of Asphalt Pavement

超薄磨耗层技术作为一种新型的预防性养护技术,可有效地应用于交通量大、路面性能要求高的高速公路路面轻微病害的矫正性养护,具有抗滑、抗车辙、抗磨耗、降噪等特点,且施工简单、快捷、可靠。结合公路病害处理实例,从材料选择、混合料设计等方面对这一技术展开研究。

As a new-style preventive maintenance technology, ultrathin wearing layer can be effectively ap- plied in corrective maintenance of tiny diseases of expressway＇s pavement which has heavy traffic and high re- quirement on road performance. It has such characteristics as skid resistance, rut resistance, abrasion resistance, noise reduction. Otherwise its construction is simple, fast and reliable. Combining with cases of highway disease treatment, the paper studies the technology in terms of choice of materials, design of mixture, and so on.
