An important feature is provided by the processing unit that controls the speed aasto a closed-loop modeavoiding speed calibrations and tension fluctuation effects.

General lab – PC softwares: Different models are available conforming to aashhto various Maintenance Spares Technical trainings Warranty Academy. All the accessories have to be ordered separately. For more information, contact: A real-time test graph and transducer data are displayed on the touchscreen.
The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel.
The dry unit weight specified is aazhto the minimum percent compaction allowed by the using agencys field compaction specification. 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 aashhto 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.
Soil testing Back to Results Print. Conforming to all the above and other major International Standards, designed for moulds to and to To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers.

CBR motorized loading press The machine feature a rigid two column frame with upper crossbeam, which can be adjusted in height and locked aadhto position with locknuts. 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.
Soil – CBR loading presses: The machine include a precision load ring, 50 kN cap. Hand operated CBR loading press The machine feature a rigid two column frame with upper crossbeam, which can be adjusted aasbto height and locked in position with locknuts.

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.
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 important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator.
The 50 kN capacity and the fully variable test speed of 0. The CBR value obtained in this test forms an integral part of several flexible pavement design methods. The 50kN capacity and fully variable speed of 0. The machine include a precision load Home Products Search results Results for: Soil testing Lab Services: The drive force is provided by a mechanical jack housed in the base cabinet.

Prior to the test, the operator can aawhto travel limits for automatically ending the test. 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 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 load jack, DC motor and controls are housed in a specially designed base cabinet.
The front panel is also fitted with an emergency button and two operating led: The load jack, DC motor and controls are aashhto in an ergonomic cabinet. The front panel is fitted with an emergency button for prompt stopping of the machine. No external transducer is required for displacement measurement.
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.
