The Bituminous Laboratory verifies asphalt concrete hot mix (ACHM) designs submitted by contractors and performs Loaded Wheel Testing for evaluation of the rutting potential of designs. Examples of work performed in this laboratory include: absorption and specific gravity tests for aggregates and ACHM, volumetric analysis of contractor submitted ACHM mix designs, laboratory scale Loaded Wheel Testing, ACHM density determination, and asphalt binder extractions.
