• Abstract:
  A research study has been conducted to evaluate the existing MD SHA hot-mix asphalt aggregate friction testing procedure and provide recommendations for modifications or replacement. Phase 1 of the study consisted of a literature review and a correlation analysis of existing aggregate friction and other aggregate property data. As a result of phase 1, it was determined that the existing British Wheel/Pendulum test procedure, along with a new procedure would be investigated. Phase 2 of the study focused on development of an aggregate screening procedure, refinement of the British Wheel/Pendulum procedure and development of the new test procedure utilizing the NCAT Polisher and Dynamic Friction Tester. New draft MSMT specifications have been developed for the test procedure and a new aggregate friction test program is ready for implementation by MD SHA.
