Asphalt concrete is characterized by high compression strength but low tensile resistance – application of a membrane between two asphalt layers retards reflective cracking between asphalt layers by:
Increasing asphalt tensile strength
Bearing a significant proportion of horizontal tension forces, thus ensuring even stress distribution over a large area
Geogrids and geotextiles are mostly applied in rehabilitating asphalt pavements with a geotechnical membrane spread over the asphalt layer to be rehabilitated, followed by application of a new upper asphalt layer.
Thirty years of experience have proven that the application of geotextiles/geogrids reduces maintenance of the asphalt road, extends maintenance intervals and produces favorable cost/benefit ratios.
A Hatelit C type Geogrid – advantages:
• Improving the quality of the asphalt pavement.
• A significant reduction in maintenance costs.
• Reflective cracking repulsion.
