Geogrids
Geosynthetic formed by a regular network of integrally connected elements with openings that allow interlocking with the surrounding soil, rock, earth and other materials to provide them with reinforcement. Composed of continuous elements joined by weaving techniques.
Fortgrid Asphalt
Fortgrid Asphalt are high tenacity polyester (PET) biaxial geogrids, designed to reinforce and control the reflection of cracks in asphalt concrete layers. They are impregnated with a bituminous copolymer that makes them compatible with asphalt and facilitates their adherence. The size of their openings allows a high interaction with the aggregate that makes up the mix and direct contact between the surfaces involved. They are resistant to high temperatures, have compatibility with the thermal expansion of asphalt concrete, have high tensile strength and cyclic loading resistance, which increase the tensile strength in the new asphalt layer, increase the resistance to reflective cracking and fatigue life, and reduce maintenance costs.
Usage
Asphalt binder reinforcement
___________ Advantages ____________
Controls the reflection of cracking in asphalt overlays.
They increase the fatigue life of asphalt layers.
Absorb horizontal tensile stresses occurring in the lower plane of the asphalt layer.
Increase the resistance of asphalt layers to rutting.
