At present, sufficient experience has been gained in the design and construction of roads with the use of geocells, in particular, on weak soils. One of the main building properties of geocells is their ability to maintain strength and carrying capacity. When under loads an uneven subsidence occurs, geocells bend and take the base surface shape, redistribute load over a large area and reduce subsidence unevenness.
However, normally geocells are made of HDPE with no additional reinforcement, and the material strength is usually determined by presence of secondary polyethylene and strip thickness. The main drawback of this is high elasticity of the material that can be up to 250%, thus geometry stability of the cells under loads cannot be maintained. As a result, we see filler material over-consumption and structure deformations.
To overcome this drawback, we performed the reinforcement of polyethylene strips which are used in geocells production. This was made in order to obtain an additional safety margin and stability of the geometric characteristics, since polyethylene stretches under pressure, temperatures and over time.
Now we would like to present a geocell for road construction – namely in structures that require high and uniform indicators of strength and durability.
