CBR loading machine
Digital and continuous measurement with penetration monitoring with an accuracy of 0.001 mm. Load measuring range: up to 50 kN.
The device is only available in the laboratory. Only employees of the Department of Hydrogeology and Engineering Geology of the AGH University of Science and Technology are authorized to provide service. Laboratory works for external entities are carried out on the basis of a formal order (form available at: http://home.agh.edu.pl/~labgg/dokumenty/) after registration at the Administrative Office of the WGGIOŚ. The implementation of the research requires the consent of the Head of LBGiG.
The device is used to determine the California bearing ratio (CBR), immediate bearing index and linear swelling for soils and mixtures used in embankment constructions. Tests performed in accordance with PN-EN 13286-47:2022-04.
The device allows to exert pressure with a controlled force over time with simultaneous measurement of the strain of the tested sample. It also gives the possibility of determining bearing capacity parameters for natutal soils, aggregates and unbound and binder-bound mixtures.
