Pavement design is a field of civil engineering that focuses on the planning, design, and construction of road surfaces, such as highways, streets, and parking lots. The goal of pavement design is to create a durable and safe roadway that can support the anticipated traffic loads and environmental conditions. This involves consideration of factors such as pavement materials, thickness, drainage, and surface texture. Engineers also consider factors such as traffic volume, speed, and climate when designing pavements to ensure they meet the specific needs of the intended use. Overall, pavement design aims to create a long-lasting and cost-effective road surface that can safely and efficiently accommodate transportation needs.
