• Description:
  In 1994 there were significant changes to the Colorado Department of Transportation's (CDOT's) both mix asphalt program. Several programs culminated at this time. These programs included 1) aggregate and mix specifications, 2) variable laboratory compactive efforts, 3) field verification, and 4) European testing equipment. Furthermore, the use of the new SUPERPAVE binder tests and gyratory compactor will be implemented soon in Colorado. Coincidentally, 1994 was one of the busiest paving seasons for the COOT in quite some time. As a result, nine different projects were paved on the 1-25 corridor. Furthermore, the use of the new SUPERPAVE binder tests and gyratory compactor will be implemented soon in Colorado. The purpose of this paper is to document the HMA properties used on the projects for 1-25. This will provide information that can be correlated to the long-term performance of these pavements 5, 10 and hopefully even 15 years into the future. The tracking of these pavements' performance will then provide valuable information for the development or modification of specifications in the future. They may also provide new data for the use of life-cycle cost analysis, and the use of life-cycle cost analysis, and the implementation of the SUPERPAVE binder and gyratory recommendations.
