Pavement engineering is a branch of civil engineering focused on the design, construction, and maintenance of pavements for roads, highways, and airfields. It involves selecting appropriate materials and techniques to ensure durability, safety, and performance under various traffic loads and environmental conditions. Key aspects of pavement engineering include material selection, structural design, and performance evaluation. Engineers use tools like computer modeling and field testing to assess pavement conditions and make informed decisions. The goal is to create efficient and sustainable surfaces that enhance transportation infrastructure while minimizing costs and environmental impact.
