| Abstract | There is a widespread recognition and desire need by agencies and asphalt paving industry to use performance testing to complement volumetric properties and help ensure satisfactory asphalt pavement performance. Accordingly, there has been several initiatives throughout the nation to develop Performance Engineered Mixture Design (PEMD) processes for asphalt pavements. This informational brief provides practitioners with information about index-based performance tests that can be implemented within a PEMD process to help improve performance and prolong service life of asphalt pavements. It is aimed to serve as a general overview and to provide context for PEMD process and how it fits into the big picture. A five-step procedure guideline is presented in this document for the selection and incorporation of performance tests in an index-based PEMD process for asphalt mixture design and acceptance. Seven evaluation factors and associated hierarchical levels are identified and presented as part of an approach for screening and assessing the overall appropriateness of specific performance tests for use in an index-based PEMD process. The approach is demonstrated on selected performance tests using illustrative examples and following certain assumptions. State highway agencies (SHAs) and contractors can make use of the suggested five-step procedure guideline presented in this informational brief for their own selection of performance tests, depending on their specific needs, goals, capabilities, and resources, as part of an index-based PEMD process. |
