Application of Geosynthetics in Highway Engineering

Abstract

Geosynthetics have good engineering characteristics, such as lightweight, low price, high practicality, strong corrosion resistance, and high strength, so they are widely used in engineering construction, which has played multiple roles in highway engineering, such as protection, drainage, filter layer, isolation, reinforcement, and seepage prevention. This article will introduce the types, characteristics, and working principles of geosynthetics and list the application methods and conditions of common hazards in the construction of highway engineering. It will illustrate the importance and applicability of geosynthetics in highway engineering through the method that combines theory with actual engineering, and it is hoped that it can be used for reference to similar projects by listing the application case of the Yinchuan–Guyaozi expressway in China. In the end, it will point out the problems that exist in geosynthetics in the aspect of theoretical research, testing technology, design calculations, specification criteria, and so on, and the directions of their future development.
