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.

This book gathers the proceedings of an international conference held at Empa (Swiss Federal Laboratories for materials Science and Technology) in Dübendorf, Switzerland, in July 2020. The conference series was established by the International Society of Maintenance and Rehabilitation of Transport Infrastructure (iSMARTi) for promoting and discussing state-of-the-art design, maintenance, rehabilitation and management of pavements. The inaugural conference was held at Mackenzie Presbyterian University in Sao Paulo, Brazil, in 2000. The series has steadily grown over the past 20 years, with installments hosted in various countries all over the world. The respective contributions share the latest insights from research and practice in the maintenance and rehabilitation of pavements, and discuss advanced materials, technologies and solutions for achieving an even more sustainable and environmentally friendly infrastructure.

The final product of the Strategic Highway Research Program (SHRP) Asphalt Research Program is the SUPERPAVE (registered trademark) mix design system for new construction and overlays. This system employs a series of new performance-based specifications, test methods, and practices for material selection, accelerated performance testing, and mix design. This report documents these new specifications and procedures in a format suitable for eventual American Association of State Highway and Transportation Officials (AASHTO) standardization.

A research project was conducted to identify and document current modifications to ARIZONA 815c (75-blow Marshall method) used to develop gap-graded asphalt rubber asphalt concrete (GG AR AC) mix designs, and to develop and test improvements to provide a standard mix design method for use by contractors and consultants. Based on field performance data provided by the Arizona Department of Transportation (ADOT), the existing mix design method was successful and should serve as the standard for comparison of proposed improvements. Best practices were synthesized to develop proposed improvements. Three aggregate sources and two asphalt rubber (AR) binders were used for initial testing of the existing (control) mix design method and of the proposed changes. Rebound of compacted AR AC specimens was evaluated, as were Rice test results at 6% and 7% AR binder by weight of mix. The composition of the AR binders (rubber gradation and content) had more effect on the results than which mix design method was used. Additional replicate testing was performed by MACTEC and ADOT to confirm these findings. Changes to the AR AC mix design method consist primarily of making and curing Rice specimens in the same manner as Marshall specimens, tighter temperature ranges for mixing and compaction, incorporating Asphalt Institute calculations in a "User's Guide," and improving presentation. An ADOT construction project was used as an "acid test" to pilot the proposed mix design method and provide materials for a four-laboratory round robin to evaluate the precision of testing AR AC materials. The precision of round robin testing appears very similar to that of conventional asphalt concrete mixtures based on data from Proficiency Sample Programs of the AASHTO Materials Reference Laboratory and ADOT. The results indicate that the mix design method developed can be used by qualified laboratories to provide suitable AR AC mix designs
