摘要: |
The conversion from viscosity grading asphalt binders to Superpave Performance Graded asphalt binders (PGAB) has required a major change in the testing equipment and protocols. The test results from the PGAB showed large variations between laboratories. These variations could result in disputes between PGAB suppliers and State Highway Agencies. This study looked at possible causes for the test result variations as well as possible remedies. The project also conducted Asphalt Binder Technician Workshops to convey the interim findings of the project as well as to learn where potential problems may exist based upon feedback from the Technicians conducting these tests. |
