1. Avaliação de camadas de proteção para geomembranas de PVC e PEAD / Assessment of the performance of protective layers for PVC and HDPE geomembranes
The performance of non-woven geotextiles and soils as protection elements of polyvinyl chloride (PVC) and high density polyethylene (HDPE) geomembranes is studied. The materials used comprised PVC geomembranes of 1,0 and 2,0 mm thickness and HDPE geomembranes of 1,5 and 2,0 mm thickness while the protective layers were of non-woven polyester (PET) geotextile

2. Comportamento carga-alongamento de geotêxteis não tecidos submetidos à tração confinada
The use of geosynthetics in reinforced soil structures has shown a marked increase due to its simplicity, speed and cost-effectiveness. The choice of the geosynthetics depends on the compatibility between the mechanical properties of the geosynthetics and the characteristics of the project. The tensile force mobilisation in the reinforcement depends on its t

3. Fluência de geotêxteis não tecidos através de ensaios confinados / Creep of non woven geotextiles on confined tests
This work presents results of creep tests on no woven geotextiles tested in confined lab tests. In the used equipment, the reinforcement is confined between two soil layers, allowing both materials to have freedom to deform with time. In those tests, a vertical stress is applied to the soil that transfers load to the reinforcement. The tests were performed u

4. Emprego do método SIM para obtenção das curvas isócronas e de ruptura por fluência / Use of SIM to obtain isochrone and creep rupture curves
A obtenção de resultados de fluência em geossintéticos (isócronas e curva de ruptura por fluência) requer longo tempo de observação e rigoroso controle laboratorial. Dessa forma, muitos produtos disponíveis no mercado brasileiro não foram ensaiados quanto a este fenômeno dificultando sobremaneira a elaboração de projetos mais seguros e econômic
