An important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects. Soil testing Back to Results Print.

As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel.

Soil testing Lab Services: Maintenance Spares Technical trainings Warranty Academy. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at The front panel is also fitted with an emergency button and two operating led: To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers.

California bearing ratio, pavement subgrade, subgrade, pavement subbase, subbase, pavement base course, base course, pavement design, flexible pavements, bearing ratio.

The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification.

Soil – CBR loading presses: For more information, contact: The load jack, DC motor and controls are housed in an ergonomic cabinet. 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 This test method is used to evaluate the potential strength of subgrade, subbase, and base course material, including recycled materials for use in road and airfield pavements.

AASHTO T, Test equipment Controls

Conforming to all the above and other major International Standards, designed for moulds to and to This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator. The machine include a precision load ring, 50 kN cap.

Soil – CBR apparatus: Different models are available conforming to the various Prior to the test, the operator can impose travel limits for automatically ending the test. No external transducer is required for displacement measurement.

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 criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on a geotechnical engineering evaluation.

The CBR value obtained in this test forms an integral part of t1993 flexible pavement design methods. The drive force is provided by a mechanical jack housed in the base cabinet. CBR motorized loading press Aazhto machine feature a rigid two column frame with upper crossbeam, which can be adjusted in height and locked in position with locknuts.

All the accessories have to be ordered separately. 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.

Active Risk Management

The front panel is fitted with an emergency button for prompt stopping of the machine. 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.

The firmware allows performance of transducer calibrations and setting of up to 10 aasgto profiles, saving data onboard. The 50kN capacity and fully variable speed of 0. A real-time test graph and transducer data are displayed on the touchscreen. 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, qashto the range of water content permitted for field compaction by using agencys field compaction specification.

The display also show the travel direction of lower platen. The 50 kN capacity and the fully variable test speed of 0. Home Products Search results Results for: For applications 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 xashto optimum water content of a specified compaction effort.
