冻区高速公路新旧路面基层接缝处理施工技术

Construction Technology of Joint Treatment of New and Old Pavement Base of Highway in Frozen Area

在高速公路改扩建过程中,如何做好新旧路面基层的接缝处理工作是目前面临的重要问题。论文结合京哈高速GQ02工区起讫桩号K1004+080~K1024+300标段的具体情况,以路面设计文件以及结构层拼接的基本方法为基础,分析冬季低温条件下新旧路面层接缝位置拼接的施工工艺,以做好低温条件下路面基层接缝的施工处理。

In the process of highway reconstruction and expansion,how to do a good job of old and new road base joint processing work has become an important problem we face.Based on the concrete situation of the section K1004+080~K1024+300 starting and ending pile in GQ02 work area of Beijing-Harbin Expressway,the paper analyzes the construction technology of joint position joining of old and new pavement layers under the condition of low temperature in winter on the basis of pavement design documents and the basic method of structural layer splicing,so as to do a good job under the low temperature condition of the road joint construction treatment.
