Geospan AS

Polyester geogrid

Specifications: Reinforcement

Effectiveness and Application

Geospan AS is produced from high-modulus bituminized polyester fibers to enable its solid grip with asphalt concrete layers. Thanks to the solid grip, geogrids have no problem to withstand tensile stresses and distribute them over a large area.

Geospan AS use allows:

a higher road durability;
less surface defects (rutting, shearing, cracks and so on);
protection from reflective cracks.

Geospan AS application:

reinforcement and crack prevention of asphalt concrete pavement layers
