Geogrid for Road Construction in Nepal

Abstract

New technological and improved methods for road construction to achieve stability, as well as sustainable service, seems really important in the present context. The use of Geogrid in road provides two major functions- base reinforcement and subgrade stabilization. Geogrid improves the ability to obtain compaction in overlaying aggregates. It confines aggregates together and strengthens subgrades material to resist traffic loads to a greater extent acting as a reinforcement. Problems like loose soil, seepage, poor drainage, water table variation directly affect the base materials of the road which decreases bearing capacity, the strength of soil, lifespan, and performance of the road. Geogrid minimizes many such road problems along with increasing the capacity of the road and distributing load in a large area. Though it seems a little costlier at the construction phase of road, it has proved its great performance over the full duration of its service with efficient results. Making the implementation of geogrid for road construction to meet the improved version of development in the transportation sector of Nepal is the main focus of our project.
