Roads support daily life across cities and rural areas. A strong road keeps people safe and supports trade. It also helps in reducing long-term repair costs. For this reason, road pavement design needs careful planning from the very start. One of the most important parts of this process involves selecting the right materials for the pavement structure. Material selection affects the strength and lifespan of the road. It also depends on safety and maintenance needs. Poor choices lead to cracks and potholes. It leads to early failure. Smart choices support smooth travel and long-term value. Experienced engineers treat material selection as the foundation of every successful project.
