The Standing Committee on Pavement Preservation (AKT20) is concerned with identifying and promoting the proactive use of cost-effective treatments to extend the lives of existing pavements through research, education activities, and discussions among practitioners, researchers, and industry representatives. The committee identifies, promotes, and supports research that quantifies the impact of preservation activities, identifies their optimal pavement condition and application timing, quantifies performance outcomes, and quantifies and documents the benefits of pavement preservation to the transportation roadway infrastructure.
