BRA-30 and BRA-31 Penetration Pistons for CBR Tests are an integral piece of field equipment used in California Bearing Ratio (CBR) testing. They conform specifically to CBR tests, and meet requirements for ASTM, AASHTO and Army Corps of Engineers (COE) methods. In testing, the piston penetrates the soil, and load on the piston is compared to penetration depth to determine CBR values.

Model BRA-30 is equipped with a 3/4in threaded male connector, while BRA-31 has a 1/2in threaded male connector.

BRA-32 Piston Extension Set for Field CBR Test is required for proper positioning of the piston, and the BRA-33 Connector Set for CBR Test is also required to connect the piston and extensions to the Load Ring.

Features:

  • Designed to penetrate soil and base course materials for determination of CBR values
  • Conforms to AASHTO, ASTM and COE standards
