Maintenance and rehabilitation of asphalt layer with geogrids
MAINTENANCE AND REHABILITATION OF ASPHALT FOLDER WITH GEOMAL GRIDS
Most common failures of flexible pavements to be solved with geogrids
A flexible pavement is a structure with a wearing course made of asphalt concrete, which is characterized by its ability to deform or flex under applied loads, rather than being rigid and non-deformable. These pavements are commonly used on highways, streets, runways, airports, bicycle lanes and pedestrian areas for their versatility and ease of maintenance.
The most common failures of this type of pavement are cracks in the wearing layer associated with the repetitive application of loads caused by vehicle traffic passing over the pavement surface, although they are also associated with the thermal gradient, oxidation of the asphalt and changes. volumetric in the subgrade, among others. Over time, these cracks interconnect, generating increasingly closer patterns that additionally result in deformations and detachments on the surface, as shown below:
Solution with Fortgrid Asphalt geogrids:
In order to reinforce, control the reflex of cracks, increase the useful life and reduce maintenance and rehabilitation times of asphalt overlays, geogrids are used FORTGRID ASPHALT. These geogrids are characterized by being resistant to cyclic loading, are resistant to high temperatures and installation damage, achieving a stable condition of the pavement structure in the long term.
