This method is used for the laboratory evaluation of subgrade and subbase coarse materials in road construction. To perform this type of test, we propose moulds with various accessories listed in the table below and manual compaction rammers. Different models are available conforming to the various relevant specifications.
In this section moulds, suitable accessories and rammers conforming to ASTM, AASHTO, UNE and UNI are shown.
An alternative (and preferable) method of compacting is to use an automatic compactor. For more information, see link to other products below.
The CBR penetration test can be performed with a number of loading presses, some of them specifically designed for CBR tests, and others with multiple applications (Universal models), at different levels of sophistication. See link to other products below.
