Around 4,000 BC, the first roadways were constructed using stone and wood. The Romans popularized the use of stone pavement for road construction a few thousand years later, mostly in North Africa and Europe, though there is evidence that similar techniques were also used in South America and India.
Over time, road construction has developed steadily. By adjusting slope slopes and stone thickness, stones were eventually arranged in a regular, compact pattern and covered by smaller stones to create a solid layer, which resulted in stronger, smoother roads. These days, asphalt and/or concrete are typically used to build roadways.
Setting out, earthworks, and pavement construction are the three main steps in the construction of modern roadways. In this article, we will discuss how much it costs to build a road per mile.
