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

To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers.

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

Active Risk Management

Conforming to all the above and other major International Standards, designed for moulds to and to The machine has built-in data acquisition with four channels dedicated to two strain aqshto load cells and two potentiometric linear transducers; one of each can be used during the test. The front panel is fitted with an emergency button for prompt stopping of the machine.

The drive force is provided by a mechanical jack housed in the base cabinet. Different models are available conforming to the aahsto The CBR value obtained in this test forms an integral part of several flexible pavement design methods. The machine include a precision load ring, 50 kN cap.

A real-time test graph and transducer data are displayed on the touchscreen.

Prior to the test, the operator can impose travel limits for automatically ending the test. Soil testing Lab Services: The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification.

The front panel is also fitted with an emergency button and two operating led: The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel.

Soil – CBR apparatus: 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 the optimum water content of a specified compaction effort. The load jack, DC motor and controls are housed in an ergonomic cabinet.

All the accessories have to be ordered separately. Soil aasto CBR loading presses: The load jack, DC motor and controls are housed in a specially designed base cabinet. The machine include a precision load An important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects.

The firmware allows performance of transducer calibrations and azshto of up to 10 test profiles, saving data onboard. 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.
