Application of Bubble Concrete in Expressway Widening Project in Soft Subgrade Area

Yu Hangbo,Lv Xiling,Jiang Tianhe,Zhou Honghai  
In the existing expressway extension projects,the traditional construction method of splicing the old with the new roadbeds is easy to produce the different settlement,which results in the pulling to crack the structures at both sides of pavement and embankment so as to greatly increase the maintenance fund after the highways put into operation. Bubble concrete can resolve the different settlement difficulty of the old and new roadbeds because of having the physical mechanics characteristics of the solidified independence,low-spring damping,adjustable strength,wear and so on,and at the same time able to greatly save the land resource and to shorten the construction period. According to the engineering cases,the article introduces the application of bubble concrete in the soft subgrade expressway widening project.
