GEOCOMPOSITES

Geocomposites are polymer products, made by connecting two or more types of geosynthetics, e.g. geogrid with nonwovens. They are used both for soils (separation and reinforcing function) and for asphalt pavements (reinforcing function, especially for repairs).

Reinforcing geocomposites utilize the benefits of a nonwoven geotextile and a reinforcing woven or knitted geotextile or geogrid, an integral unit being formed by stitching through or thermal bonding.

ASPHALT REINFORCEMENT

Material of asphalt layers has low tensile strength - it results in formation of cracks in the asphalt layer that can lead to reduction of usability and service life of the asphalt topping.
Geocomposites are most frequently used as reinforcing geosynthetics material for asphalt layers. They increase tensile strength of the asphalt layer, accept a considerable part of horizontal tensile stress in the asphalt layer and ensure its uniform distribution in larger areas in case of a careful design.
Geocomposites also prevent in formation and spreading of reflex cracks by absorption of shear forces.
A properly designed geocomposite reduces permanent deformations and beating ruts.
Geocomposites can be used for reinforcement of both new asphalt roads and roads already damaged by cracks. Road service life is extended considerably by reduction of creating and spreading reflex cracks.
