Description

Hot mix asphalt (HMA) is a mixture of approximately 95% aggregates and 5% asphalt cement, the glue that holds the asphalt together. HMA is produced through several types of mixing processes, whereby the aggregate is blended, dried, heated, and finally coated with asphalt cement in a coating plant. Hot mix asphalt pavement is the predominant road-paving material in the United States, with approximately 96% of paved roads being asphalt pavement. From highways to driveways to runways, asphalt is the most popular and practical choice. The Sunrock Group has over 60 years of experience producing hot mix asphalt in Raleigh NC.
