PERFORMANCE OF OPEN-GRADED FRICTION COURSES
This report documents installation and evaluation of an experimental pavement using an open-graded asphalt friction course, placed as part of the FHWA's Demonstration project 10. Two different open-graded mixes -- one having a maximum aggregate size of 1/2-in and the other 1/4-in -- and a standard NYS 1A top mix were evaluated. Performance of the experimental pavement was determined by measuring air-void content, asphalt cement penetration and viscosity, skid resistance, rutting, and noise, and by visual observations of water drainage and splash and spray by passing traffic in wet weather. Results showed that the open-graded pavements performed better than the standard NYS 1A top.
