Renforcement des chaussées par des matériaux composites : Cas d’études projet PN30 Mascara

Abstract

The Algerian Road network, vital for socio-economic development, is experiencing accelerated degradation due to heavy traffic, harsh climatic conditions, and aging of material. These deteriorations compromise pavement durability of the roadways, increasing maintenance costs and reducing their efficiency. To remedy this, composite materials are emerging as an innovative solution, offering superior strength, lightness, and durability. This report analyzes their application in pavement reinforcement by examining their properties, modeling techniques (via ANSYS), and a practical case study (PN30 Mascara project). Geogrids, in particular, optimize stress distribution and reduce cracking. The study highlights the importance of a multidisciplinary approach (geotechnics, material mechanics) and validates the effectiveness of synthetic reinforcements through numerical simulation. Finally, it showcases technological advancements and research prospects for more resilient infrastructure.
