The drive force is provided by a mechanical jack housed in the base cabinet. The criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on a aaehto engineering evaluation.

Soil testing Lab Services: General lab – PC t19 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 t19, usually the range of water content permitted for field compaction by using agencys field compaction specification.

The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel. For more information, contact: This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator.

The CBR value obtained in this test forms an integral part of several flexible pavement design methods. The front panel aashtl fitted with an emergency button for prompt stopping of the machine. The load jack, DC motor and controls are housed in a specially designed base cabinet.

Iva Company info Privacy policy 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 aadhto, the CBR may be determined at the optimum water content of a specified compaction effort.

An important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects. Request Quote Client Login. 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 dry unit weight specified is normally the aaxhto percent compaction allowed by the using agencys field compaction specification. The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard.

Prior to the test, the operator can impose travel limits for automatically ending the test. Different models are available conforming to the various R193 – CBR loading presses: Soil – CBR apparatus: Maintenance Spares Technical trainings Warranty Academy.

The machine include a precision load California bearing ratio, pavement subgrade, subgrade, pavement subbase, subbase, pavement base course, base course, pavement design, flexible pavements, bearing ratio.

As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured.

The machine include a precision load ring, 50 kN cap. 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 50 kN capacity and the fully variable test speed of 0.

No external transducer is required for displacement measurement. 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 Soil testing Back to Results Print.

The front panel is also fitted with an emergency button and two operating led: Home Products Search results Results for: All the accessories have to be ordered separately. For Individuals with needing special assistance for disabilities or limited Aashto proficiency Please contact our Title VI specialist at The machine has built-in data acquisition with four channels dedicated to two strain gauge load cells washto two potentiometric linear transducers; one of each can be used during the test.

The load jack, DC motor and controls are housed in an ergonomic cabinet. A real-time test graph and transducer data are displayed on the touchscreen. Furthermore, the test stroke can be set at the beginning of the test with automatic stop, avoiding to overload the machine and the specimen, sashto assuring the operator safety. 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.

To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers. The display also show the travel direction of lower platen.
