Concrete roads are a common sight. Many people may not know, however, that Detroit was the first city to have a concrete road installed. This one-mile long road was constructed in 1909, and cost $13,492.83. Currently, about 30% of the interstate highways throughout the United States have concrete pavement.
Paving Industry Highlights
The U.S. paving industry is a major employer. According to 2017 figures, 195,603 businesses employed 284,626 individuals. This industry also brings in substantial revenue. In 2017, for example, this revenue amounted to $36 billion.
How Concrete Paving Is Made
Concrete is made with a combination of different aggregates, water, and cement. Crushed stone, gravel, and sand, for example, comprise 60% to 65% of concrete’s makeup. In addition to the aggregate mix, 15% to 20% of concrete is composed of water, and ten percent to 20% consists of cement.
It’s important to note that concrete can also withstand substantial amounts of pressure. In general, its compressive strength ranges between 3,000 to 7,000 pounds per square inch. This is one of the many reasons why concrete is used for roads, sidewalks, and other structures. Speed bumps can also be made out of concrete.
The Benefits of Smooth Pavement
When pavement is smooth and in good condition, it has a longer lifespan. Experts indicate that roads can last as much as ten percent to 25% longer. When roads are in poor condition, however, there are added costs to drivers. The Road Information Program estimated that this could be as much as $400.00 a year.
When roads are well-maintained, less fuel may be needed. According to a Swedish study, vehicles use less fuel on smooth rather than rough roads. This can be as much as ten percent less. While that may not sound like a substantial amount, it can make a positive impact on reducing fuel usage and costs.
