AASHTO T, Test equipment Controls
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 50kN capacity and fully variable speed of 0. Soil testing Back to Results Print. The CBR value obtained in this test forms an integral part of several flexible pavement design methods.
Request Quote Client Login. The drive force is provided by a mechanical jack housed in the base cabinet. For more information, contact: The drive force is provided by a mechanical jack housed in the base cabinet which also accomodates the motor and the electric panel.
The 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.
Soil testing Lab Services: Prior to the test, the operator can impose travel limits for automatically ending the test. The criteria for test specimen preparation of self cementing and other materials which gain strength with time must be based on aahto geotechnical engineering evaluation. General lab – PC softwares: Home Products Search results Results for: 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.
As directed by the engineer, self cementing materials shall be properly cured until bearing ratios representing long term service conditions can be measured. The front panel is fitted with an emergency button for prompt stopping of the machine. An important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects.
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. The load jack, DC motor and controls are housed in a specially designed base cabinet.
Aasjto to all the above and other major International Standards, designed for moulds to and to Soil – CBR loading presses: Follow us YouTube LinkedIn. The machine include a precision load A real-time test graph and transducer data are displayed on the touchscreen.
The display also show the travel direction of lower platen. The dry unit weight specified is normally the minimum percent compaction allowed by the using agencys field compaction specification.
All the aashyo have to be ordered separately. No external transducer is required for displacement measurement. This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator.
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.
Active Risk Management
The load jack, DC motor and controls are housed in an ergonomic cabinet. The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard.

The machine include a precision load ring, 50 kN cap. To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers. 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 50 kN capacity and the fully variable test speed of 0.
