Asphalt concrete is the mixing of aggregate and liquid asphalt at elevated temperatures in an asphalt plant. Typically, asphalt concrete mixtures are divided into three mixture categories: dense-graded; open-graded; and fine-graded as a function of the aggregate gradation used in the mix. In addition to our standard mixes Reed & Graham, Inc. proudly produces more environmentally responsible asphalt concrete mixes such as (WMA) warm mix asphalt manufactured at lower temperatures and (RAP) recycled asphalt pavement manufactured using a percentage of recycled aggregate.
