Bearing Ratio GB/T50123-1999 CBR Test Equipment for Soil and Pavement Base
The CBR-1 type bearing ratio tester is designed for conducting bearing ratio tests on various soils and mixtures with particle sizes less than 40mm. This essential geotechnical testing instrument determines the load-bearing capacity of designed pavement, pavement base, subbase, and subgrade material layers after compaction in specified test tube molds.
Product Features
- Compact design with high output capacity
- User-friendly operation and setup
- Comprehensive system including main unit, force ring, penetration rod, loading plate, dial indicators, and expansion measurement device
- Ideal for laboratory and field testing applications
Applications
This bearing ratio (CBR) tester is used to evaluate the bearing capacity of various soils, pavement bases, and sub-base materials after specimen preparation in standardized test tubes, making it essential for civil engineering and construction quality control.
