摘要: |
Over the past 10 to 15 years, Interstate pavements in northern Florida have experienced a significant number of failures, primarily due to rutting. It was believed that the present fine-graded, 50-blow Marshall-designed mixes were inadequate to withstand current loading conditions. The newly developed Superpave system represented an opportunity to address several of Florida's asphalt pavement problems. Thus, the Florida Department of Transportation made a concerted effort to implement Superpave technology in 1996. During this period, eight projects were changed from the traditional Marshall mix design to Superpave. Although the new procedure offers potential for improved pavement performance, there has been very little experience nationally with its field application. Florida's early experiences with the field implementation of Superpave are documented, including changes to Superpave specifications to address the permeability problems encountered on the 1996 projects. |
