INSTALLATION FOR ASSESSMENT OF FATIGUE asphalt concrete under cyclic dynamic effect

摘要

1. Apparatus for assessing the fatigue of asphalt concrete with cyclical dynamic loads, comprising a frame, a lifting table arranged to change the height of the beam-specimen positioning node sample beam loading unit adapted to apply a cyclic dynamic loads and to measure the displacement and biasing force comprising a connecting rod-slider mechanism, characterized in that the beam-specimen positioning assembly comprises clamping jaws mounted on the ends of the beam-specimen na It is parallel to the transverse axis of the frame symmetry, and intermediate resilient base made as a container filled with the model soil, with tight contact with the facing thereto the reference beam plane, wherein the biasing assembly of the beam-specimen loading element is configured to position it in the middle of the reference beam .2.
