scope:

This UFC prescribes materials, mix design procedures, and construction practices for flexible pavements.

PURPOSE.

This UFC provides guidance for the preparation of drawings and specifications for road and airfield flexible pavements using asphalt cement materials. The term "asphalt" is used herein instead of bitumen or bituminous (a generic term for both asphalt and tar materials) because asphalt is the material typically used in pavement construction. In the past, tar or coal tar was used only in instances where fuel resistance was required. Due to problems with emissions, tar is no longer used in flexible pavement construction except occasionally as a sealer. This UFC also provides useful information for design engineers, laboratory personnel, and project managers concerning mix design, materials, production, and placement of the various asphalt mixtures.
