Performance Evaluation of Warm- and Hot-Mix Asphalt

Hot-mix asphalt (HMA) is produced at temperatures between 140°C and 160°C and even higher mixing temperatures can be required to produce some mixtures, namely, asphalt rubber and polymer-modified asphalt (PMA) mixtures. These temperatures ensure that the aggregate is dry, the asphalt coats the aggregate, and the mixture has a suitable workability.
