This paper briefly introduces the problems of reflection cracks existing in pavement engineering and the development of pavement reflection cracks in geotechnical networks. The basic survey of geotechnical networks in Britain, Switzerland and China is briefly introduced. The application of Shanggong network in the prevention and treatment of pavement reflection cracks is reviewed. The mechanics mechanism, test method and economic benefits of application of geotextile to preventing and controlling reflection cracks are discussed. It also analyzes the problems that need to be studied in the future and the key technologies.
