Performance of Permeable Friction Course (PFC) pavements over time Conference Paper uri icon

abstract

  • Performance of Permeable Friction Courses (PFCs) was evaluated over time and compared against other mixture types. Several pavement sections including Asphalt Rubber (AR) PFCs, Performance Graded (PG) PFCs, and dense-graded Hot Mix Asphalt (HMA) were monitored over a four-year period. On-site measurements included noise, drainability, texture, friction, and skid. The change of these variables with time as well as the influence of traffic, binder/mixture type, aggregate classification, and climatic region was evaluated. Accident data was also gathered and analysed on a more comprehensive number of pavement sections across the state of Texas. Performance of PFCs over time was adequate. PFCs had lower overall noise levels when compared to HMA, and AR-PFCs were quieter than PG-PFCs. With regard to drainability, the water flow values had a tendency to increase early in the life of the pavement and remain relatively constant afterwards. PG-PFCs showed better drainability as compared to AR-PFCs. Texture for PFCs remained practically unchanged over time. Both AR- And PG-PFCs had superior texture and skid vs. HMA pavements. With regard to friction and skid, sections with lower quality aggregates had inferior values. The accident data indicated that PFCs reduce the number of accidents, injuries, and fatalities on roads in Texas. 2014 Taylor & Francis Group, London.
