Tlhe Strategic Highway Research Program (SHRP) was a $150 million 5-year research program targeted toward four areas: asphalt, concrete, highway operations, and pavement engineering. This work resulted in 128 products, each of which may be a device, procedure, specification, etc. Many of these products and other aspects of the SHRP research have application to airfield pavements, but these technologies must be evaluated on an individual basis to determine their usefulness. These reviews have been organized into fact sheets that provide a brief description of the product and an evaluation of whether the technology has application to Federal Aviation Administration (FAA) pavements and the technical issues involved in their use. The SHRP asphalt mixture design system (SUPERPAVE*) has been evaluated in relation to current FAA asphalt mixture design. Asphalt mixture tests (repeated simple shear at constant height, flexural beam fatigue, and thermal stress restrain specimen test), utilized during SHRP, revealed no significant differences in performance-related material properties between heavy-duty SHRP and heavy-duty FAA laboratory-prepared specimens. Recommendations on the adoption and/or revision of aspects of the SHRP asphalt technologies for use by the FAA are included. |
