摘要: |
A combination of three studies has allowed an examination of long-lasting pavements in Washington State and specifically those pavements on the Washington State Department of Transportation (WSDOT) route system. The findings of these studies are summarized in this paper. The major findings support the view that thick asphalt concrete pavements (greater than 160 mm) should have long lives. The performance of WSDOT wearing courses, though good, can be improved. Specific focus to improve performance should be on construction practices. Generally, these results support the view that "mill and fill" surface rehabilitation is very effective. Finally, the current in-service WSDOT thick asphalt concrete pavements come close to meeting the goals associated with perpetual pavements. |
