Research for AASHTO Standing Committee on Highways. Task 412. Adjustments to the Superpave Volumetric Mixture Design Procedure for Selecting Optimum Asphalt Content
| 项目名称： | Research for AASHTO Standing Committee on Highways. Task 412. Adjustments to the Superpave Volumetric Mixture Design Procedure for Selecting Optimum Asphalt Content |
| 摘要： | The objectives of this research were to (1) summarize and evaluate successful approaches currently being used by SHAs to adjust the Superpave volumetric mixture design to obtain higher asphalt binder contents; (2) verify the increase in optimum asphalt content through a limited laboratory experiment that compares successful approaches with the current AASHTO standards; and (3) document these results as proposed appendixes or amendments to AASHTO R 35, AASHTO M 323, or both. |
