Asphalt is all around us, but it’s a paving material that many don’t know enough about. Take our quiz about the basics of asphalt.
- What is the most recycled material in the U.S.?
Answer: A. Asphalt! Asphalt is the most recycled material in the U.S. with a recycle rate of 99 percent, according to the National Asphalt Pavement Association. In comparison, steel cans are recycled at a rate of about 70 percent, aluminum cans are recycled at a rate of 55 percent, and glass is recycled at a rate of 31 percent. Additionally, recycling asphalt also leads to the recycling of other products, like roofing shingles, tires, and metal castings, and it also conserves other materials, like asphalt binder.
2. What percentage of the U.S.’s 2.3 million miles of road are paved with asphalt?
Answer: D. 94%. Asphalt is the go-to choice for paving America’s roadways because it is durable, cost-effect, quick to install, simple to maintain, and it lasts for decades with proper maintenance. In addition to 94 percent of America’s roads being paved with asphalt, 65 percent of the U.S.’s interstate system are also asphalt.
3. Which of the following is the earliest record of asphalt being used?
- Used for waterproofing in the Indus Valley civilization from approximately the 5th millennium BCE.

However, all of the other options are also examples of the past use of asphalt; its use has been documented by the ancient Greeks, the Sumerians, in Babylon, by ancient Japan, and more.
4. Asphalt is called the “perpetual pavement” because it can easily be renewed by removing, recycling, and reapplying the top layer; the Perpetual Pavement Award is given to recognize pavements that have lasted at least 35 years and have never had a structural failure.
