Armogruntovye system "Slavros".

In order to reduce the right of way for the construction of embankments in cramped conditions (presence of buildings, communications, roads) is necessary to the construction of retaining walls. In recent years, along with the traditional designs of retaining walls of reinforced concrete, all the more widespread construction of reinforced soil, which is an artificial construction, made by layering the mound geosynthetic soil reinforcement materials, in particular - pultruded polyethylene geogrid "Slavros CO". Reinforced soil to some extent, similar to concrete, wherein in one case the armature is connected with the ground, in the other - with the concrete. However, comparison of these two media is not quite true as the reinforcement of reinforced concrete intended for sensing the tensile forces in the element structure and reinforced ground, in particular using unbound soil likely to be a field only compressive stresses. Consequently, the effect of reinforcement is unequal limiting normal deformation in different directions.

Materials "Slavros" for the roads of the Far East

Currently, the Far East, one of the priorities is to support the development of the transport network. The sad fact is that in the Far East, there are still difficult to transport over the territory. Therefore it is extremely important to the construction of modern, comfortable, efficient transportation routes for the socio-economic development and the normal life of the Far Eastern District. Deadlines and difficult climatic conditions of the Far East forced builders to apply innovative technologies and materials. Such materials include the full range of geosynthetic materials. High technology of geosynthetics can find a use for them in virtually all sectors of the economy.

"Slavros" - at the service of the Russian roads

The Russian market is very necessary and required in the construction of geosynthetics continues to develop. By careful study of market trends, needs, road maintenance, and the company is developing "Slavros" - the largest Russian manufacturer of geosynthetics. Along with the implementation of well-proven materials - biaxial geogrids "Slavros-SD", volume geogrids "Slavros-GR", uniaxial geogrids - "Slavros-CO", drainage composite "Slavros-drain", geomembranes, the company continues to expand its product line, and well as to develop innovative materials that can improve the quality of national roads.

"Slavros": a solid foundation railways

Roads of the transition to innovative development provided by large-scale use of new efficient technologies and materials in order to increase the reliability and service life of road construction, increasing the technical level and transportation and operational condition of railways, to reduce the cost of road works.

"Slavros-RADO" - to help engineers

At the end of last year at an international conference atm, the company "Slavros" - the largest Russian manufacturer of geosynthetic materials presented to specialists and the public own calculation program reinforced pavement "Slavros-RADO" created with the support of Rosavtodor and allows to perform calculations using the biaxially geogrid "Slavros diabetes." Until recently, the use of reinforcing layers of geosynthetic material was of Experimental character. With the release of ODM 218.5.002-2008 "Guidelines for the use of the polymer geogrids (geogrid) to enhance the pavement layers of granular materials", designed by specialists of FSUE "RosdorNII" and STC "Geotechnology" in 2008 with the support of Rosavtodor, the situation changed and there was a tool for the design, which enables calculation of geosynthetic materials and lay in the documentation. To simplify the design of reinforced choice of clothes on the basis of ODM 218.5.002-2008 program was created "Slavros-RADO" (Certificate of Conformity № ROSS RU.SP15.N00229 of 12.04.2010). Calculations of non-rigid type of pavement roads shared network made it according to the requirements of regulations ODN 218.046-01, fashion and ODM 218.5.002-2008 2-2001. The program offers the possibility to choose the most appropriate solution. The concept of the program is based on the methods of the modern theory of elasticity applied to the calculations of the pavement structure. Eliminating unjustified margin of safety design varying the thickness of the layers, arranging additional layers of cheap local materials, using a layer of geosynthetic materials, the designer achieves the desired result.
