  The CoreLokTM is a system for sealing asphalt samples so that the sample densities may be measured by water displacement method.

Samples are automatically sealed in specially designed puncture resistant polymer bags.

Densities measured with the Corelok system are highly reproducible and accurate. The results are not dependent on material type or sample shape.

The included GravitySuite PC software package calculates and manages your data for ease of operation.

Ships in two boxes.
  • Fully automatic sealing process
  • Puncture resistant, easy to use polymer bags for lab and field sample testing
  • Measurements are not dependent on mix specific calibrations
  • Works with different sample sizes and shapes
