Abstract：Coal mining subsidence areas are widely distributed in China,thusly it is very difficult for some highways to bypass a mining subsidence area. The construction feasibility of highways in coal mining subsidence regions depends on their roadbed-stability and lurking deformations. Based on lots of literatures and documents reviews,the vehicle loads on the roadbeds,the roadbed-lurking deformation mechanism of a mining subsidence area,the calculating method and control technology of road-lurking deformations and control technologies were reviewed and summarized. The result pointed out that it is necessary to analyze the stability of the collapsed overlying strata and their effects on roadbeds in coal mining subsidence areas,and that borehole grouting design parameters for roadbeds reinforcements can be determined by the inversion of roadbed-lurking deformations limit indexes.
