What is the minimum tensile strength required for the geogrid used in asphalt pavement reconstruction?

The minimum tensile strength required for the geogrid used in asphalt pavement reconstruction is 10 kN/m. This specification is based on the need for adequate reinforcement in the pavement structure to prevent deformation and failure under load. A tensile strength of 10 kN/m ensures that the geogrid can effectively distribute loads and mitigate stresses that can lead to cracking and other forms of distress in the pavement.

Geogrids serve a critical role in enhancing the performance and longevity of asphalt pavements by providing tensile reinforcement that holds the pavement layers together, ultimately improving the structural integrity and performance of the roadway. A proper tensile strength guarantee is essential, as insufficient strength would not provide the necessary support, leading to potential failures in the pavement system over time.
