The California Bearing Ratio (CBR) is a penetration test for evaluation of the mechanical strength of road sub grades and base courses. The CBR test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area. The measured pressure is then divided by the pressure required to achieve an equal penetration on a standard crushed rock material, 50 KN (5000 kgf) Capacity with Strain Rate of 1.25 mm per minute, CBR Mould with collar & base plate, Penetration Piston, 50 mm dia with bracket, Perforated Brass Swell Plate with stem & locknut, Displacer Block 148 mm dia with T-Handle, Annular & Slotted Metal Weight 2.5 kg, Aluminium Tripod Stand, Rammer 50 mm internal dia 2.6 kg & 4.89 kg, Proving Ring 10 kn capacity with Calibration Certificate in teak wooden carrying case.
