How Asphalt Cement is Made The Manufacturing Process ...

Jun 18, 2019  Asphalt paving mixes made with asphalt cement are usually prepared at an asphalt mixing facility. There are two types of asphalt mixes: hot-mix and cold-mix. Hot-mix asphalt (HMA) is more commonly used while cold-mix asphalt (generally mixes made with emulsified or cut-back asphalts) is usually used for light to medium traffic secondary roads ...

How is Asphalt Made? A Look Inside the Manufacturing Process

Sep 26, 2018  How Is Asphalt Made? Manufacturers create asphalt in a plant, of which there are some 3,500 in the United States. Manufacturers create an aggregate mixture in line with specific project requirements, which they thoroughly wash and dry. Next, they thin the asphalt cement by heating it up, adding a solvent, or emulsification in water.

How Is Asphalt Made? Sunland Asphalt

To make WMA, certain emulsions, zeolites, waxes or water are added to the asphalt cement before it is mixed with the aggregate. This technique allows for production at much lower temperatures, which reduces energy consumption, petroleum use and emissions of harmful gasses. The manufacturing of asphalt is a varied yet precise process.

Asphalt Cement Encyclopedia

Asphalt Cement Background Asphalt is a heavy, dark brown to black mineral substance, one of several mixtures of hydrocarbons called bitumens. Asphalt is a strong, versatile weather and chemical-resistant binding material which adapts itself to a variety of uses. Asphalt binds crushed stone and gravel (commonly known as aggregate) into firm, tough surfaces for roads, streets, and airport run-ways.
