• 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.
