| Abstract: | The continuously reinforced concrete pavement(CRCP) has its own characteristics of working with cracks,which can be combined with the jointless technology.Based on this,we propose a new measure to absorbe the shrinkage deformation of the bridge through the approach pavements in small and middle integral jointless bridges.Combined with the topic of the jointless technology in small and middle bridge in western China,an indoor model test was implemented.And some experimental results have been yielded from the... |
