(108) The cpfat value is a damage equivalent impact factor according to ENV 1991-3, Annex B:
cpfat =1,2 for surface of good roughness <Pfat = 1 for surface of medium roughness
An additional impact factor for verification of sections within the distance of 6,0 m from an expansion joint should betaken into account according to ENV 1991-3, Annex B. (For more details see also ENV 1991-3, Annex B: Fatigue life assessment).
