Understanding the differences between hot mix asphalt and

Hot mix asphalt or HMA is the designation given to asphalt mixtures that are heated and poured at temperatures between 300 and 350 degrees Fahrenheit. This type of asphalt is the most commonly used asphalt type in the United States for highways, interstates and roads due to its flexibility, weather resistance and ability to repel water.
