沥青路面现场热再生技术适用性及实施效果分析

Analysis on Applicability and Implementation Effect of Hot In-place Recycling Technology for Asphalt Pavement

现场热再生作为一种预防性养护技术,能够在病害发生初期阻止和延缓病害的发展,进一步延长路面使用寿命。文章结合现场热再生工程实例,重点对其技术特性、适用性进行了阐述,并结合养护后路面的车辙指标发展趋势,采用指数模型分析了在不同交通荷载作用下现场热再生技术延长的路面使用寿命。

As a preventive maintenance technology, hot in-place recycling technology can prevent and delay the occurrence and development of pavement disease at early stage and extend pavement service life. Taking engineering with hot in-place recycling as an example, this paper introduces the features and applicability of hot in-place recycling technology, and combining with the development trend of pavement rut depth index, analyzes the service life extended of pavement in different traffic load using exponential regression model.
