Overview:

The Load-Ratio (CBR) Tester is used to conduct load-ratio tests on various soils and pavement subbase and subgrade materials after preparing test specimens in specified test cylinders. It complies with the TG3430-2020 Code for Geotechnical Testing of Highway Soils and the GB/T 50123-2019 Standard for Geotechnical Testing Methods.

The maximum particle size of the mixture should be controlled within 25 mm, with a maximum of 40 mm.

Features:

1. 7-inch color touchscreen display with curve plotting, data storage, and printing capabilities.

2. Supports both international and domestic standards: British Standard BS 1377-4, American Standard ASTM D1883, and Chinese Standard GB/T 3430-2020.

3. Customizable test deformation recording points and loading speeds to meet the requirements of different test standards.

4. Data processing capabilities, including automatic calculation of CBR values.

5. Servo motor control with software speed feedback and stepless adjustment of loading speed.

6. Built-in microprinter capable of printing data stream lists and test results.

7. Data upload capability (optional).
