Automatic Soil Cbr Machine

A California Bearing Ratio (CBR) machine is a laboratory apparatus used to evaluate the strength of sub-grade soils and road base materials. It measures the resistance of a soil sample to penetration by a standard plunger under controlled moisture and density conditions, simulating wheel load effects. The result (CBR value) helps in pavements Key Features: • Penetration plunger and loading frame for applying static loads • Dial gauge or digital sensor to record penetration vs load • Molding tools and permeameter for sample preparation • Water bath for soaking samples during testing • Sturdy frame with calibrated load measurement mechanism • Conforms to standard test methods (e.g., ASTM D1883 / AASHTO T193) The machine provides reliable, repeatable CBR values for soil classification and pavement design.
