The paper proposes an impregnation composition for cement concrete roads used as an
ice-phobic coating. The composition has been made based on keratin-containing components derived
from animal waste with the addition of water-soluble polymers. The main parameter of serviceability
of the coating impregnated with the developed composition was assessing the adhesion resistance of
ice crust to concrete under the influence of mechanical loads. For this purpose, tests of big specimens
(surface area 1925 cm2
) in laboratory conditions with application of vibration and impact loads
and modelling of thermal stresses were conducted. The test results showed the effectiveness of the
ice-coating, as in all experiments, the uncoated specimens showed a greater resistance of the ice crust
to mechanical stresses. An additional evaluation parameter was comparing the water absorption
capacity of coated and uncoated concrete. The test results showed a significant difference in the water
absorption capacity of the uncoated specimens, exceeding the coated specimens by 47%. Due to the
results obtained, it will be possible to use the impregnation compound effectively to improve the ice
resistance of cement concrete coatings.
