Geosynthetic materials are a sustainable solution for pavement applications, but this depends on the materials and their application. Geosynthetics are artificial materials used in pavement construction to improve soil stability, drainage, filtration, separation, and other functions. Geosynthetics in pavement foundations can reduce the need for natural resources such as aggregates, sand, and gravel, allowing conventional construction materials to be used more sustainably. Furthermore, geosynthetics have a longer life span and a lower carbon footprint during production, transportation, and installation when compared to traditional materials. The effectiveness of the geosynthetic material used depends on various factors, including the materials used, the manufacturing process, the application, and the end-of-life disposal. The article seeks to present an overview of geosynthetic products like geogrid and geofoam, as well as their interactions with different pavement foundation soils. This paper delves deeper into the load transfer mechanism in geogrid, and arching effect in the geofoam, and the optimal placement of these materials to improve load-carrying capacity and reduce surface deformations by increasing soil shear strength. Furthermore, the benefit of using geofoam as a replacement material for soil to promote sustainability by conserving natural resources and effectively reusing renewable and recyclable materials was studied. An in-depth evaluation of geofoam response under cyclic loading was also studied. |
