Vibration Measurement and Analysis of low embankment freeway pavement and roadbed Under Traffic Loadings

ZHA Wenhua1,2,HONG Baoning1,XU Yi1(1.Geotechnical Engineering HoHai University NanJing 210098,China;2.Department of Source and Management,Anhui University of Science and Technology,Anhui HuaiNan 232001,China)  
The traffic loading make pavement and roadbed produce dynamic response.For mastering and analyzing vibration response of low embankment freeway pavement and roadbed under Traffic Loadings,the thesis have spot measurement on a low embankment engineering segment of LianYunGang-YanChen Freeway,testing dynamic response of pavement and different depth roadbed under different vehicle and velocity using strong shock apparatus and dynamic earth pressure cell.According to the analysis about testing result,some value conclusions were obtained,Therefore it has certain significant for conducting roadbed design and dispose of low embankment freeway aftertime.
