Application of geosynthetic materials for road structures

Abstract

In this article, the authors examines the application of geomaterials in road constructions, it economic indicators, the dependence of surface density and unit cost, as well as strength and unit cost, are analyzed. The economic and technical advantages of using woven geomaterials are shown. Geosynthetic materials allow increasing the strength of road structures and reducing the cost of construction while maintaining strength and reliability. Geogrid road has all the permits and technical documentation: the calculation methods are developed for the solution of road construction. Woven geomaterials are the best to use and have a number of advantages, but now nonwoven geomaterials are usually used in Russia, which is caused by imperfect design methods that do not take into account the strength of the geomaterial and reduce the density of pavement when using thick geomaterials. Geomaterials are geosynthetic products for strengthening slopes, slopes, coastal zones, road surfaces and other territories that need strengthening of soils. Geomaterials, among other things, are an excellent protection against erosion, environmentally safe, reliable, have a long useful life and are easily installed. Depending on the needs and type of territory, geogrids, geomatics and road geosets are used.
