• Abstract:
  The Arizona Department of Transportation (ADOT) has developed specifications and procedures to ; ensure the quality of the hot mix asphalt materials purchased by the Department. The document ; recording these specifications and procedures is the Standard Specifications for Road and Bridge ; Construction. The 2008 Standard Specifications is the reference used throughout this document. ; Specifications, however, are constantly changing as technology advances, materials change, and mix ; design criteria change. The objectives of this project are to: review the state-of-the-industry in Arizona ; with a focus on equipment and technologies currently being used; review ADOT’s construction ; operations conformance history reports to identify probable causes of non-conformance; perform a ; critical review of the asphaltic concrete sections of the current standard specifications; recommend ; asphaltic concrete specification changes; and prepare a report of the activities. ; These objectives were met by holding a series of workshops in Arizona with both ADOT and ; contractor personnel participating. The workshops gave participants an opportunity to discuss issues and ; concerns with details of the existing specifications. Based on this input, a critical review of the existing ; specifications was prepared and recommendations for revising the specifications to national state-of-thepractice ; were made. In addition, recommendations were made for revisions to ADOT’s construction ; operations conformance history reporting system.
