FORTGRID ASPHALT geogrid reinforcement against cyclic loading<\/h3>\n

As shown in Figure 1, asphalt layers are subjected to repetitive loads that generate tensile and shear stresses. The FORTGRID ASPHALT geogrids<\/strong> act as an intermediate barrier that distributes stresses and prevents cracks in the base from reflecting on the surface of the new asphalt overlay. In addition, this principle is widely applied in road infrastructure with geosynthetics<\/a><\/strong>improving the structural performance of the pavement.<\/p>\n

Technical performance results<\/h3>\n

According to evaluations carried out by Walubita (1)(2), the FORTGRID ASPHALT geogrids<\/strong> significantly increase the number of load repetitions required to reach failure. This demonstrates a higher efficiency than fiberglass geogrids, resulting in a greater structural contribution to the pavement. In this way, a reduction of premature deterioration is achieved, as evidenced by the studies of the Transportation Research Board (TRID)<\/a>.<\/p>\n

The benefit obtained is quantified by the Geogrid Efficiency Factor (GEF)<\/strong>which represents the ratio between load cycles in the reinforced and non-reinforced condition. This indicator, adjusted by a shift factor<\/strong>The concept of geogrid design, allows the translation of laboratory results to real field conditions, establishing the number of times that the geogrid increases the bearing capacity of the asphalt overlay. This concept is applied in the design of geosynthetic reinforced pavements<\/a><\/strong>where structural efficiency translates into greater durability and reduced maintenance costs.<\/p>\n

The characterization of the FORTGRID ASPHALT Geogrid<\/strong> under the standard ASTM D7556<\/a><\/strong> demonstrates its high capacity for elastic recovery throughout the pavement's life cycle. Unlike aged asphalt, which loses its elasticity over time, the geogrid maintains its resistance to permanent deformation, which translates to increased durability, reduced reflective cracking and improved structural performance<\/strong>.<\/p>\n

In conclusion, the incorporation of the FORTGRID ASPHALT Geogrid<\/strong> in the structure of asphalt pavements represents an important efficient technical solution<\/strong> to extend its service life, control crack reflection and improve its performance under repetitive loads. These advantages, backed by technical studies and standardized testing, confirm the value of the geosynthetic reinforcement<\/strong> as an essential part of modern road engineering.<\/p>\n
