Evaluation of Rubber Asphalt and Other Pavement Treatments in Arizona

This paper will discuss that in order to determine the benefit and relative value of a material, it is necessary to compare its performance with other possible treatments. In this paper the comparisons are over a range of time and accumulated Equivalent Single Axle Loads (ESALs). Over the years Arizona Department of Transportation (ADOT) has used a variety of materials and techniques for overlays and surface treatments, depending upon the requirements of the pavement sections involved. Most of these treatments and materials were selected because of past performance history in Arizona. The arrival of new and innovative materials, techniques and specifications, encouraged increasing use of several new treatments such as asphalt rubber over time. The availability of a well-maintained pavement management database provided an opportunity to make an unbiased comparison of treatments on the basis of up to 15 years performance data. It should be stressed that the evaluation was based on observed performance rather than a controlled design experiment. Consequently, valuable information can be gained by “trend” review, regardless of statistical significance of differences in performance. These comparisons are valid for airfield pavements as well as highways.
