REINFORCEMENT OF ASPHALT LAYERS WITH GEOMETRICS
REINFORCEMENT OF ASPHALT LAYERS WITH CONGEOGRIDS
Expansion of a road with geogrids:
When there is a widening joint on a road, the asphalt mixture layer is susceptible to cracking due to differences in the stiffness or compressibility of the subgrade.
Installing a geogrid FORTGRID ASPHALT between the old asphalt layer and the new asphalt layer or between the asphalt base and the new asphalt layer in the joint area, generates a biaxial projection of the forces that expands the thin resistant prism, turning it into one in the shape of an inverted pyramid of greater volume, which It means a greater mechanical offer to tolerate the efforts that arise.
Thanks to the resistance to cyclic loading, high temperatures and low installation damage, the geogrids FORTGRID ASPHALT are an advanced alternative for the reinforcement of asphalt overlays. Its balance between open area and resistance offers high shear resistance (adhesion) at the interface that guarantees achieving the results for the expected useful life.
How to install geogrids
Geogrids can be installed on any type of surface, as long as adhesion at the interface is guaranteed. For this purpose, verification of the amount of binder irrigation through the in situ adhesion test allows determining the optimal amount of asphalt binder required. It is recommended to use fast breaking cationic asphalt emulsion
