An electrically-operated California Bearing Ratio (CBR) machine was designed, fabricated with locally-sourced materials, calibrated and tested with the aim of providing high precision machine obtainable at lower cost. Materials were selected based on the ability to withstand mechanical loads, stiffness and dimensional stability, wear resistance, corrosion resistance, machinability and cost-effectiveness. The major component parts were designed using standard equations. For material components such as the loading frame, CBR moulds and reaction rings, mild steel was used, hardened medium carbon steel was used for the plunger, while high-grade spring steel was used for the load-measuring components for high elastic recovery. Calibration result gave proving ring constant as 0.02 kN/div. CBR test results on soil samples under unsoaked conditions gave CBR values ranging from 4.85 – 6.91 %, indicating poor to fair soils requiring stabilization or treatment for subgrade material. For soil tested under soaked conditions, the lowest CBR value of 0.82% showed poor subgrade soil that requires substantial stabilization, while the sample with the highest CBR value of 3.15% requires significant improvement. Statistical analysis of data using Minitab software version 2018 applied Fisher Pairwise tests for differences of means at 95% level of significance, which showed that soaked 2.5mm and unsoaked 5mm samples with P = 0.007 and soaked 5mm and unsoaked 5mm with P = 0.14 are significantly different for the top, and soaked 2.5mm and unsoaked 5mm having P = 0.028, are significantly different for the bottom. CBR values for all other top and bottom samples are not significantly different.
