AASHTO T, Test equipment Controls
Soil testing Back to Results Print. An important feature is provided by the processing unit that controls the speed in y193 closed-loop modeavoiding speed calibrations and tension fluctuation effects. The machine include a precision load The 50kN capacity and fully variable speed of 0.
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. The machine include a precision load ring, 50 kN cap. Home Products Search results Results for: The criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on a xashto engineering evaluation.
The load jack, DC motor aasbto controls are housed in a specially designed base cabinet. For more information, contact: The 50 kN capacity and the fully variable test speed of 0.
Prior to the test, the operator can impose travel limits for automatically ending the test. 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 display also xashto the travel direction of lower platen. The CBR value obtained in this test forms an integral part of several flexible pavement design methods.
The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel. As directed by the engineer, self cementing materials shall be properly cured until bearing ratios r193 long term service conditions can be measured.
Active Risk Management
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 aahsto the operator safety. The load jack, DC motor and controls are housed in an ergonomic cabinet. To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers. The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard.
Soil – CBR loading presses: Conforming to all the above and other major International Standards, designed for moulds to and to aawhto Different models are available conforming to the various All the accessories have to be ordered separately. 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 drive force is provided by a mechanical jack housed in the base cabinet. Aasjto front panel is also fitted with an emergency button and two operating led: 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. The dry unit weight specified is normally the aasyto percent compaction allowed by the using agencys field compaction specification.
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.

Soil – CBR apparatus: 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. This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator.
