The Most Versatile Asphalt Density Measurement System.
An innovative, non-nuclear method of determining SuperPave, Stone Matrix (SMA), and coarse mix asphalt air voids. CoreLok performs 5 standard lab tests:
Bulk Specific Gravity, Maximum Specific Gravity, Aggregate Specific Gravity
Porosity, % Asphalt Content
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 the material type or sample shape. The GravitySuite™ PC software package calculates and manages your data for ease of operation.
One Machine for All your Gravity Measurements of Asphalt and Aggregate.
