Structural Stability of Composite Pavement

Composite pavement systems, combining asphalt concrete and Portland cement concrete layers, offer enhanced durability and performance in high-traffic and challenging environments. This study investigates the structural stability of composite pavements by analyzing material properties, layer thicknesses, and interface conditions. A numerical analysis, validated by field measurements, is conducted to assess the effects of these factors on pavement performance. The findings highlight the significant influence of asphalt concrete stiffness and interface bond strength on overall stability. Additionally, a comparison between normal concrete pavements and composite pavements is performed to evaluate strength and cost-effectiveness. By optimizing load-bearing capacity and reducing maintenance costs, composite pavements provide a sustainable and efficient solution for modern infrastructure. The study’s insights assist engineers in designing more durable pavement structures, minimizing premature failures, and ensuring long-term performance. The research contributes to advancing construction techniques and material selection to improve road safety and infrastructure resilience.
