road construction techniques

Road construction involves preparing and creating durable pathways for vehicles. It starts with clearing and leveling the land, then laying a foundation of gravel or crushed stone for stability. Next, layers of asphalt or concrete are applied and compacted to form a smooth, strong surface. Modern techniques may include cutting-edge machinery for precise grading and paving. Throughout, engineers ensure proper drainage to prevent water damage. The process also involves setting curbs, sidewalks, and safety features. Overall, it combines planning, earthworks, material placement, and finishing to produce a reliable, long-lasting road.
