The CoreLok® is a system for sealing asphalt samples so that the sample densities may be measured by water displacement methods. 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 GravitySuite? PC software package calculates and manages your data for ease of operation.
