CBR-III Digital CBR Testing Machine
I. Purpose and scope of application:
California bearing ratio (CBR) tester is used to test the bearing ratio of various soil, pavement base and bottom materials after making specimens in the specified test tube. This test is in accordance with ASTM d1883 and BS1377:4.
The maximum particle size of the mixture should be controlled within 25 mm and not more than 40 mmII.Main parameters of the instrument:
1. Test speed: 1.27mm/min(ASTM D1883) 1mm/min(BS1377:4). Fast speed: 15mm / min
2. Test force value: 50kN force value accuracy: 0.001kn
3. Penetration rod: end diameter: 49.63 ± 0.13MM(ASTM D1883) 50±0.5MM(BS1377:4)
4. Displacement sensor: 0-25mm, graduation value: 0.01mm, linearity: 0.3%.
III.Main features:
1. 7 inch color touch screen display, with curve display, data saving and printing.
2. The deformation recording point and loading speed can be set arbitrarily to meet the needs of different test standards.
3. It has data processing function and can automatically calculate CBR value.
4. Servo motor control, with software speed feedback, loading speed stepless adjustment.
5. Built in micro printer can print data stream list and test results.
