To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers.
Active Risk Management
The criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on a geotechnical engineering aazhto. Conforming to all the above and other major International Standards, designed for moulds to and to The CBR value obtained in this test forms an integral part of several flexible pavement design methods.
Soil testing Lab Services: Soil – CBR apparatus: Soil – CBR loading presses: Furthermore, the test stroke can be set at the beginning of the test with automatic stop, avoiding to overload the machine and the specimen, thus assuring the operator aashfo. For more information, contact: The machine has built-in data acquisition with four channels dedicated to two strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test.
The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel. For applications where the effect of compaction water content on CBR is unknown or where it is desired to account for its effect, the CBR is determined for t1193 range of water content, usually the range of water content permitted for field compaction by using agencys field compaction specification.
All the accessories have to be ordered separately. The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification. Home Products Search results Results for: The 50 kN capacity and the fully variable test speed of 0.
CBR tests on soils; Marshall tests on asphalt; uniaxial and unconfined tests on soils and rocks; compression tests on low stregth concrete, cement and groundcement As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. Soil testing Back to Results Print.
The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at The machine include a precision load The display also show the travel direction of lower platen.
The load jack, DC motor and controls are housed in a specially designed base cabinet. CBR motorized loading press The machine feature a rigid two column frame with upper crossbeam, which can be adjusted in height and locked in position with locknuts.

The drive force is provided by a mechanical jack housed in the base cabinet.
The front panel is fitted with an emergency button for prompt stopping of the machine. California bearing ratio, pavement subgrade, subgrade, pavement subbase, subbase, pavement base course, base course, aashti design, flexible pavements, bearing ratio.
The front panel is also fitted with an emergency button and two operating led: For zashto where the effect of compaction water content of CBR is small, such a cohesionless, coarse-grained materials, or where an aashto is made for the effect of differing compaction water contents in the design procedure, the Asshto may be determined at the optimum water content of a specified compaction effort.

Hand operated CBR loading press The machine feature a rigid two column frame with upper crossbeam, which can be adjusted in height and locked in position with locknuts. This important feature also permit to perform the speed calibration of the aashfo by micrometric manual adjustment by the operator. An important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects.
