摘要
在高速公路改扩建路面拼接施工技术应用中,对于同一结构层,由于原结构体与新拼接部位存在材料组成的不同、性能差异等原因,在使用效果上也会发生较大的变异,故拼接就存在一定的施工难度。要将新、旧路面结构拼接成一体,保持整体稳定性和路面耐久性,需采取一定的技术措施和控制方案。
In the application of the splicing to the highway extension project it is difficult to splice the old one into the new one. This is because material variance and performance difference exist between the original one and the splicing spot though it is in the same structural layer. So some technical measures and control program should be taken to keep the splicing project stability and durability.
