Data from approximately four hundred plant mix asphalt pavement projects were analyzed by an outside materials consulting firm after being gathered by Highway Department personnel. Data obtained included age, most recent traffic count, pavement thickness, asphalt type and supplier, gradation and dust ratio and Marshall mix design data. Each project was field rated as to appearance, ride, settlement, raveling, and rutting. Longitudinal and transverse cracking was rated by frequency and severity in each quarter mile segment. Projects studied were on the interstate, primary or secondary systems.
