It has been estimated that over 60 asphalt mix designs are being specified by the various local governments and design consultants in the Denver metropolitan area. As material batches are ordered for delivery to these various agencies, the producers are required to constantly change their mixing formulations and plant operations. This constantly changing process results in inefficiencies in production time and cost to the buyer, as well as variability in the process. The problem is intensified when towns and communities order small amounts of material for a local street project. In March, 1994 a Government Forum was held in conjunction with the annual meeting of the Colorado Asphalt Pavement Association. At this forum, a decision was made to organize a Task Force to address this problem and provide recommendations for asphalt paving materials in the Denver Metropolitan area. This report presents the recommendations of that Task Force. The recommendations include gradation, asphalt cement type, additives, RAP, voids, and laboratory design properties.
