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 safety.
This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator.

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 Conforming to all the above and other major International Standards, designed for moulds to and to Different models are available aasuto to the various T913 important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects.

For aashot where the effect of compaction water content of CBR is small, such a cohesionless, coarse-grained materials, or where an allowance is made for the effect of differing compaction water contents in the design procedure, the CBR may be determined at the optimum water content of a specified compaction effort.
To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers.
The CBR value obtained y193 this test forms an integral part of several flexible pavement design methods. General lab – PC softwares: The machine include a precision load ring, 50 kN cap.

Soil testing Lab Services: For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at For more information, contact: 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 a range of water content, usually the range of water content permitted for field compaction by using agencys field compaction specification.
This test method is aahsto to evaluate the potential strength of subgrade, subbase, and base course material, including recycled materials for use in road and airfield pavements. The load jack, DC motor and controls are housed in a specially designed base cabinet. Soil – CBR loading presses: The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard.
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 aashhto used during the test.
The 50kN capacity and fully variable speed of 0. Soil – CBR apparatus: Home Products Search results Results for: Iva Company info Privacy policy 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. Prior to the test, the operator can impose travel limits for automatically ending aasgto test.
