California Bearing Ratio (CBR) testing machine for IS 2720 pavement soil tests — manual and motorised variants available at Multi Trade Combines, Guwahati, shipped across Northeast India.
The CBR (California Bearing Ratio) Testing Machine measures the bearing capacity of compacted subgrade soils and granular subbase materials before pavement layers are laid. The result — expressed as a percentage of the load required to penetrate a standard crushed-stone sample — drives pavement thickness design under IRC and MoRTH guidelines. Every highway, state road and urban road project in Northeast India that uses flexible pavement design requires CBR data at design stage and during construction quality control.
Multi Trade Combines supplies both hand-operated and electrically motorised CBR machines to road-project quality labs, engineering colleges and materials testing agencies across Assam and the Northeast. Manual machines suit sites with no stable power supply — common in remote NHIDCL and BRO project areas in Arunachal Pradesh and Manipur. Motorised machines with digital load readout are preferred by accredited labs where IS 2720 compliance and printable test records are required. We ship from our Guwahati counter; call for current stock details.
In stock at Multi Trade Combines, AT Road, Guwahati — serving Northeast India since 1991
Road quality-control labs on NHAI, NHIDCL and PWD projects are the primary buyers — every project requires in-situ or remoulded CBR tests at formation level and at subbase compaction checkpoints. Engineering colleges and polytechnics in Assam, Meghalaya and Nagaland maintain CBR setups for soil mechanics practical work. Private soil investigation firms serving real-estate and industrial developers in Guwahati's expanding construction belt use CBR data to specify foundation depths and slab thicknesses. The machine pairs logically with cube mould sets, compression testing machines and aggregate testing equipment — Multi Trade Combines is the region's one-stop civil lab equipment supplier for the entire geotechnical and materials testing chain.

The California Bearing Ratio test in India is governed by IS 2720 (Part 16). The test measures the bearing strength of subgrade soil under a standard penetration plunger at a controlled rate of 1.25 mm per minute. Both motorised and manually operated machines must produce a minimum force of 50 kN. Call +91 91812 13332 for machine specifications.
Yes — Multi Trade Combines stocks both manually operated (hand-pump) and electrically motorised CBR testing machines with digital load display, depending on current inventory. The motorised version gives a controlled and consistent penetration rate essential for accurate IS 2720 results. WhatsApp +91 76359 98826 to confirm current stock and delivery timelines.
