A COMPARATIVE STUDY BETWEEN THE GEOSYNTHETIC COMPOSITE AND CONVENTIONAL LAYER SYSTEM TO USING IN SEPARATION, FILTRATION AND DRAINAGE FUNCTIONS APPLIED ON MILITARY AMMUNITIONS SHELTERS.
How a cost composition can to proove the advantages to use geosyntethics materials in substitution to traditionals materials.
This article explain a comparative study between a mechanical protection of the a ammunition shelter made with a building cement and aggregate and other alternative protection that can to be used geosynthetic composite (geonet and geomembrane).
The mechanical protection was realized with traditionals preceedings using cement, sand and aggregate, according the traditionals specifications of the constructions. Some difficulties about the execution of this object upper a possibility to change this construction step, using a geosynthetic in that was possible to economize the global cost. Some advantages such as a quick installation and good strength to support the compacted soil that is placed over in the shelter.
Althrough the building was constructed with usual materials, was realized a comparison among two different costs compositions with the objective to compair the global price using traditionals materials and the geosynthetic one. The revenue of the labour and the material costs are compared to avaliate the best option to be used as mechanical protection over the coverage of the ammunition shelter.
The costs compositions showed that the use of geosynthetics materials are cheaper than the use of traditionals materials such as sand, granular soils and stones. But, the constructor adopted the traditional solution, using the naturals materials. This shows that how is important a marketing political more aggressive to convince traditionals engineers that the using of geosyntethics is cheaper, safety and cleanner than using conventionals materials.
