Laboratory testing of asphaltic concrete, or hot mix asphalt (HMA), complements our ability to provide construction material testing. EEC personnel are involved in laboratory mix design testing using both Marshall and Superpave criteria. We have experience in preparing dense graded mixes, open graded friction course (OGFC), permeable pavement, reflective crack index (RCI), asphalt treated permeable base (ATPB), and stone matrix asphalt (SMA) mixes. Mix designs can be prepared to meet state transportation (i.e. CDOT or WYDOT), Federal Aviation Association (FAA), or local design criteria. Our asphalt laboratory has attained accreditation through AASHTO Materials Reference Laboratory (AMRL) for asphalt testing.
