Summary:•Pavement material properties were estimated from field measurements.•Laboratory fatigue characteristics of the layer mixes were used in the analysis.•The contribution of the AC overlay in the CIR pavement condition was investigated.•The curing of the foamed material is important for the damage of the AC overlay. 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.
