Sliding joints are often used to reduce effects of shear stresses in footing bottom. This stresses can be rooted in subsoil (effect of undermining) or they can arise in structure directly (shrinkage and creep of concrete, pre-stressing) and sliding joint can be used for both of them. The asphalt belts are used to create sliding layer between subsoil and construction in most of cases. The laboratory tests are carried out to verify their behavior by shear loads at the Faculty of Civil Engineering VSB-TUO. This paper deals with testing multi-layer sliding joint and how the increasing number of belts influences reducing shear resistance in the sliding joint.
