Roads are among the most important parts of modern infrastructure. They connect cities, support businesses, improve transportation, and make everyday travel easier. But building a road is not simply about laying asphalt or concrete over the ground. A road needs to be planned and engineered carefully so that it can handle traffic, weather, water, and changing ground conditions for many years. This is where pavement design becomes extremely important. A properly designed pavement helps a road remain strong, safe, comfortable, and economical throughout its service life. On the other hand, poor design can result in potholes, cracks, rutting, uneven surfaces, water damage, and frequent maintenance. These problems not only increase repair costs but can also affect road safety and traffic movement.
