Utilization of Temperature Dependency of Asphalt Belts to Reduce Shear Stress into Foundation Structures
Original language description
Asphalt belts are commonly used to the hydro insulation of flat roofs and to the hydro insulation of foundations. These belts are also used to auxiliary function as part of roof layer or as under layer in many construction. But asphalt belts can be also used to reduce shear stress into foundation structures. The basic principle of this reduction is in application asphalt belts between foundation and concrete base layer. This creates a sliding layer which eliminates friction forces in foundation bottom. This paper explains reasons for using of sliding joint in to foundation structures and its basic function in the building. The experimental tests of modern sliding joint and their results are presented too. At the long term tests it was verified that the ambient temperature has a heavy effect of asphalt belt behavior. For this reason the new laboratory tests deal with electronic temperature control directly in the sliding joint. Such sliding joint can be also very helpful for all types of foundation which are loaded with horizontal deformations (undermining, pre-stressing, creep and shrinkage etc.).
