Get PriceDense-Graded. A dense-graded mix is a well-graded HMA mixture intended for general use. When properly designed and constructed, a dense-graded mix is relatively impermeable. Dense-graded mixes are generally referred to by their nominal maximum aggregate size. They can further be classified as either fine-graded or coarse-graded.
Get PriceMost hot mix plants have, at best, two asphalt binder storage tanks supplying multiple projects each day. Thus there was a need to limit the number of PG grades typically used in any one region. Practical Solution A practical solution is for one “workhorse grade” asphalt for normal projects and one additional grade for heavy duty pavements.
