There are many steps in road building.Construction of unpaved roads (roads without pavement) is simple.Builders clear away trees, bushes, and plants from the roadway--the strip of land over which the road will pass.They must carefully study how the road will affect the businesses, homes, traffic, plants, and animals of the area.Then they smooth out the roadway and press the surface down with a machine called a roller.This type of road is suitable for areas where few cars travelFirst, road builders choose a route, or path, for the road.Next, road builders buy the land on which they will build the road.
