Abstract: Realistic service life calculations should take into account that several types of damage may act simultaneously. The possible interactions between the various degradation phenomena that may affect concrete structures exposed to winter climate are reviewed. Concrete with compressive strength in the range 50 – 100 MPa show ice abrasion in the range 0,0075 – 0,015 mm/km ice passage, studded tire abrasion 0,5 – 3 mm/104 passage and salt-frost scaling in the order of 0 – 0,01 mm/cycle as uniform damage. The mechanisms of degradation are discussed from both a fundamental and practical point of view. Potential interaction effects are reviewed. Interaction is mainly reducing service life, as illustrated by service life calculations that address two different cases the first one involving carbonation, chloride diffusion and corrosion, and the second that accounts for ice abrasion and frost exposure.
