Daily parking floors are exposed to mechanical stress. Floor coverings in multi-storey car parks and basement garages are among the places where such systems are exposed to the heaviest stresses. Therefore, parking garage floors need durable and highly resistant coatings. In this article, we will provide information about our car park abrasion test that we developed to measure the abrasion resistance of parking garages.
Standard Tests Are Not Sufficient
Standard tests such as the Taber Abrasion Test or the BCA method cannot adequately simulate the effects of wear and tear, as they do with real parking floors, because they do not fully realize the stress scenario.
All of the starting, driving, braking and power steering processes connect the flooring system, the bond between the reinforcing layers and the bond between the coating system and the substrate to high shear stress and intense compression forces. These various stresses necessitate more realistic testing of surface protection systems (especially elastic, crack-covering coatings) exposed to heavy traffic.
Sika has developed a test method for parking floors that best simulates this stress on pavement systems under realistic conditions. In a research project at the Technical University of Kaiserslautern, this test procedure was developed as the new Parking Abrasion Test (PAT).

The test tools consist of a machine powered by compressed air (pressure ca. 5 bar) which mechanically moves a car steering wheel on the coating system and rotates it around its axis. Wheel, 400 kg
with a heavy load and with a maximum deflection angle of 100 °
are returned.
Tests are carried out in such a way that the temperature on the pavement surface does not exceed 65 ° C. In this method, we can realistically see the actual wear on the coating system. Each of Sika’s heavily trafficked surface protection systems is subjected to this testing process before being placed on the market.
