旧水泥混凝土路面加铺沥青层施工技术研究

Research on Construction Technology of Asphalt Overlay on Old Cement Concrete Pavement

随着交通量的不断增大,早期修建的很多水泥混凝土路面出现了大量沉降、断板等结构性破损病害。为了有效改善其路面使用性能,加铺沥青层方案得到了广泛应用。本文在全面了解水泥混凝土路面损坏原因的基础上,结合具体案例,对旧水泥混凝土路面加铺沥青层施工技术要点进行了分析与探究,以供参考。

With the continuous increase in traffic volume,many cement concrete pavements built in the early stage have suffered a lot of structural damages such as settlement and broken slabs.In order to effectively improve the performance of its pavement,the additional asphalt layer plan has been widely used.Based on a comprehensive understanding of the causes of damage to the cement concrete pavement,this article analyzes and explores the key points of the construction technology of the asphalt layer on the old cement concrete pavement in combination with specific cases for reference.
