California Bearing Ratio (CBR) test is an essential evaluation method used to determine the strength of subgrade soils and base materials for roadways and pavements. By measuring soil resistance against penetration, this test ensures the proper design and longevity of construction projects. The CBR test is conducted in strict compliance with internationally recognized standards, each outlining specific methodologies for consistent and reliable results:
ASTM D1883: This standard specifies the procedure for laboratory testing of soil samples to determine the CBR value, widely used in North America for pavement and subgrade evaluation.
AASHTO T193: A key standard for highway construction in the U.S., detailing the process for determining CBR values for soil and aggregate mixtures.
EN 13286-47: Used primarily in Europe, this standard defines the method for compacted unbound materials in civil engineering projects.
BS 1377, 1924: British standards providing comprehensive guidelines for testing soils, including laboratory and field CBR tests, critical for geotechnical and structural applications.
Qualitest’s QualiCBR-Series CBR Test Equipment is designed to meet and exceed these standards, ensuring precision and repeatability for every test. Our range includes two cost-effective models:
