What’s hot mix asphalt?
Hot mix asphalt is the paving material of choice for numerous applications—it provides a very smooth, quiet ride. It’s used to construct heavy duty pavements on interstate highways (I-495 and I-95), on runways at airports (Washington Dulles International Airport and Ronald Reagan Washington National Airport), and on bridges and interchangers (Woodrow Wilson Bridge and Springfield Interchange). It also serves other purposes such as liners for drinking water reservoirs and fish hatcheries. Hot mix asphalt is also used as the paving material for parking lots and driveways and it is used on playgrounds, tennis courts, hiking/bike trails, and golf course paths.
