LABORATORY CBR APPARATUS

The California Bearing Ratio (CBR) test is conducted to determine the strength of subgrade soil and base materials for road and pavement design. The test measures the resistance of a soil sample to penetration by a plunger under controlled conditions of density and moisture. The results are expressed as a percentage of standard load values. As per BS 1377-4, BS 1924. The Instrument can also be manufactured to meet the requirements of ASTM D1883, AASHTO T193, IS: 2720 Part XVI & IS: 9669 and EN 13286-47 with suitable accessories as per the standards.
