Book Description
"The overall objectives of this study are to trace the development of a state-of-the-art in specifications for materials and construction methods for asphalt pavements, identify and evaluate requirements that are performance-related, and provide a framework of a system of specifications that will assure higher quality and longer life pavements"--Page 1

Book Description
Sulfur-Extended-Asphalt (SEA) binders save asphalt, a potential energy source, by replacing some asphalt in conventional flexible pavement mixes with sulfur. These new binders appear to possess properties comparable to asphalt. The guideline manual provides the highway community in both public and private organizations with the most definitive state-of-the-art guidelines extant for using these binders. Information on design, construction, quality control, equipment, mixing plants, specifications, and safety is included.

Book Description
Excerpt from Specifications for Sheet Asphalt Paving, Adopted October 14, 1915: These Specifications Will Be Modified From Time to Time to Keep Them Fully Up to Date, Suggestions as to Modifications or Additions Are Solicited and Should Be Sent to the Secretary, or to Francis P. Smith, 131-3 East 23d St., New York City, Chairman of T 1. Upon the foundation prepared and laid as elsewhere herein specified, shall be laid the pavement proper. This shall consist of: 1. A binder course ... inches in thickness when compressed. 2. An asphalt wearing surface ... inches in thickness when compressed. Materials. 2. The materials used must comply with the requirements of these specifications and be suitable for use upon the street or streets to be paved. They shall be mixed in definite proportions by weight, depending upon their character, and the traffic upon the street, and such materials and proportions must be satisfactory to the Engineer. 3. Methods of Testing - All tests herein specified must be conducted according to official methods on file in the office of the Engineer. All penetrations at 77 degrees Fahrenheit are expressed in hundredths of a centimeter and are to be taken (except where otherwise specified) with a number two needle acting for five (5) seconds without appreciable friction under a total weight of one hundred (100) grams. 4. Refined Asphalts - The refined asphalts admitted under these specifications shall be prepared from a natural mineral bitumen, either solid or liquid, or from combinations thereof, by such methods of refining as will produce a product complying with the requirements hereinafter given. The preparation and refining of all asphalts admitted under these specifications shall be subject to such inspection at the paving plants and refineries as the Engineer may direct. Every refined asphalt admitted under these specifications, if required by the Engineer, shall be equal in quality to the recognized standard for its particular kind or type of asphalt. If desired, the Contractor may use an asphalt cement prepared at the refinery. To be acceptable this asphalt cement must comply with the foregoing general requirements for refined asphalt, as well as requirements a, b, c, d, and e for asphalt cement.

Book Description
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. Four standard mixes were identified.
