Laboratory Testing of Asphalt Belts Rheological Properties Exposed to Shear Loads / Laboratorní Měření Reologických Vlastností Asfaltových Pásů Při Smykovém Zatížení

Abstract

Abstract At faculty of civil engineering research is underway which appears with application sliding joints into foundation structures for several years. These sliding joints are applied in order reduce friction from deformation horizontal load effect (effect of undermining or shrinkage and concrete creep and also in prestressed foundation structures in order to allow introduction of prestressing) and they are usually formed from asphalt belts. To better describe the behavior of asphalt belts in sliding joint, it is necessary to know their behavior under the action shear loads over time. For this purpose many laboratory tests are long conducted both for different load conditions (size of the horizontal and vertical loads, the influence of environmental temperature) and different kinds of materials. This paper presents the current knowledge on the basis of measurements carried out so far.
