The device is a system for sealing samples for determination of bulk specific gravity (density) of compacted and loose asphalt mixtures. The system can also be used for determinating the bulk specific gravity and absorption of aggregate and stone. This product is now the standard for measurement of bulk specific gravity of open graded and absorptive compacted asphalt samples.
The samples are automatically sealed in specially designed puncture resistant polymer bags. Densities measured with this system are highly reproducible and accurate. The results are not dependent on material type or sample porosity.
