Quality Management

     Hundreds of millions of dollars are spent annually on bituminous construction and maintenance in Minnesota. It is vital to our transportation systems and economy that pavement material producers supply the highest quality, most durable hot mix asphalt mixtures to keep pavement life cycle costs affordable.

     Commercial Asphalt Co.'s research, design, and quality management program was founded in 1989 with a laboratory and staff incorporated at our Maple Grove plant facility. In 1990 and 1991 all of the remaining plants added quality management laboratories and staff.

     Commercial Asphalt Co.'s eleven hot mix asphalt plants are all MN/DOT certified. This assures the customer that all of our hot mix asphalt products are regularly analyzed and tested for compliance with various specifications including federal, state, county and city agencies as well as private engineering and consulting requirements. Additionally, our entire technician staff is MN/DOT trained and certified.

     Hot mix asphalt specifications typically include a variety of requirements pertaining to; materials, mixture design, construction requirements, quality control, pavement density, thickness and smoothness. As a material supplier, our focus is on mixture composition and constructability. Many different materials and material combinations are analyzed with various technologies. Scientific principles and engineering judgment are applied when determining material proportions that satisfy the specifications. Further, upon completion of design, the mixture undergoes verification testing by an independent organization (usually MN/DOT or a commercial testing organization) before it is approved and produced. Coring service and testing is also available for customers working on projects with density specifications.

     Our high customer satisfaction rate is the result of our investment in research, design, and quality control which yields hot mix asphalt products that meet and exceed specification. This translates into longer lasting, higher quality pavements for our region's high, medium, and low volume infrastructure systems, as well as commercial and private applications.

     Commercial Asphalt Co.'s research, design, and quality assurance team is managed at our laboratory in Blaine, Minnesota. Questions can be directed to (763) 783-0761 or (763) 783-0750.
