Develop Cost Effective Design and Rehabilitation Strategies for Permeable Friction Courses

项目名称：	Develop Cost Effective Design and Rehabilitation Strategies for Permeable Friction Courses
摘要：	Thousands of miles of permeable friction course (PFC) pavements have performed well for the last ten (10) to fifteen (15) years on Texas highways. PFC pavement reduces hydroplaning, splash and spray, pavement noise, and improves ride quality and safety in wet weather. Hundreds of miles of PFC pavements are now at the end of their service life and need rehabilitation. The most common distress observed is raveling. To date, the most widely used method of rehabilitating PFC pavement is to mill the existing layer and replace it with a new wearing layer. This is also the most conservative and most expensive rehabilitation strategy. The research team will determine if there are less expensive resurfacing options which do not include milling. The research team will review the current PFC pavement design procedures to determine if improvements can be made to achieve longer initial life. PFC pavements have many safety related advantages, but their use is on the decline because of the high cost of rehabilitation.
