Uso de Geomallas Multiaxiales Como Refuerzo en Vías sin Pavimentar con Suelos Blandos o Subrasantes Débiles

Abstract

The roads nowadays are a fundamental part of the social and economic development of any country whatsoever, since they facilitate the exchange of goods, goods and services, generating a significant growth for the nation and allowing more national and / or foreign investments, being able to increase of the economy of a people. For this reason it is so important that the tracks remain constantly in excellent structural condition. In Colombia, we have a very high percentage of primary roads in bad condition because many of them are not designed to withstand heavy vehicle loads and thus generate their constant deterioration in the short term, we remember that the roads must be designed for long periods of useful life avoiding an investment unnecessary in short periods. With respect to the above, geogrids play a major role as structural reinforcement in all types of roads; this modern element used worldwide makes the structure prolong its useful life, significantly reducing the action of vehicular loads (ditches or furrows) in Rolling, thus achieving more durable, safe and efficient routes. Due to the constant and accelerated growth of vehicular traffic, it is necessary to explore the different methods used to reinforce the roads with this type of structural element and its evolution. In this document he emphasizes the methodology used by engineers J. P. Giroud and Jie Han. The method is applied to determine the soil-geosynthetic interaction by the action of rolling loads on paved and unpaved roads. Increasing its bearing capacity, decreasing layers of stone materials, time, costs and most importantly being environmentally friendly
