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 ...

Asphalt and the production process. Hot Mix Asphalt is usually mixed at temperatures between 300 and 325 degrees, and it needs to be laid hot, no less than about 250 degrees. It must therefore be produced close to where it is needed. More than 94 percent of the nation’s two million miles of streets and highways are paved with asphalt.

Typically, the aggregate constitutes 90–95% (w/w) of the total mixture and the asphalt cement (asphalt binder) constitutes 5–10% (w/w) of the total mixture to form the asphalt concrete. In the production process, the aggregate and binder are combined in an efficient manufacturing plant which produces the specified material.
