Old and New Embankment Splicing Technology in Highway Reconstruction Project

Abstract:

In order to make a better convergence of old and new roadbed,according to treatment technology about highway reconstruction project of new and old roadbed lap,we introduced the four good construction technology detailedly used in the construction process. Four kinds of processing technology can significantly reduce differential settlement caused by road diseases,and strengthen the widening subgrade integrity.The results show that the appropriate cutting slope and excavation steps, a good degree of compaction, the rational use of geosynthetic materials, the use of the use of high quality packing can make the new and old roadbed integrity, achieve good effect of design and construction and reduced the incidence of disease.
