Abstract: To some damage characters of heave and broken of express way pavement，according field survey and calculate analysis，the primary reasons that caused pavement deformation was mining under expressway，surface horizontal deformation was the main deformation that resulted pavement distress，pavement heave and broken were caused by surface horizontal compress deformation and horizontal tensile deformation，respectively，the field monitoring showed the express way pavement heave was danger to traffic safety than pavement broken.The express way broken were influenced by expressway structure，materials and quality and surface movement deformation and so on，the following emergence measures for express way mining subsidence section were put forward form four sides，which included inspection，caution，damage pavement treatment and deformation monitoring
