摘要: |
Intelligent Compaction (IC) of soil and asphalt mixes is an innovative approach that has been utilized to achieve uniform, adequate compaction of pavement layers during construction. Commercially available IC products provide machine specific compaction values that are indirectly related to the compaction quality (stiffness) of the pavement layers. Additional methods have to be developed in order to relate these compaction values to standardized tests used to verify pavement quality during construction. The Federal Highway Administration (FHWA) has drafted Generic IC specifications for soils and asphalt pavements to facilitate the early adoption of this technology. These generic specifications are expected to serve as guidance to individual state Departments of Transportation (DOTs) in the development of specifications relevant to the respective states. In this study, the researchers seek to help ODOT develop and validate 'Special Provisions' for the use of IC rollers during compaction of stabilized subgrades. |
