Field performance and fatigue characteristics of recycled pavement materials treated with foamed asphalt

The paper concentrates on the field performance and the fatigue characteristics of cold recycled materials treated using foamed asphalt (FA). For this purpose, field measurements were performed approximately one month and one year after the pavement was placed in service. Based on this data and laboratory analysis results, there is an indication that fatigue is a minor distress factor for both the cured FA material and the asphalt concrete (AC) overlay which covers the FA. The contribution of the AC overlay in the structural condition of the cold recycled pavement is vital during the early days of the pavement life.
