The coreLok is an extremely versatile system for measurement of bulk specific gravity and maximum specific gravity (Gmm) of asphalt. The CoreLok also measures the apparent specific gravity, absorption and bulk specific gravity of fine and coarse aggregates. GravitySuite™ PC software can be used to calculate and manage the results. The CoreLok does not require an empirical calibration and the results do not depend on material type or composition.
CoreLok performs 5 standard lab tests:
Bulk Specific Gravity
Maximum Specific Gravity
Aggregate Specific Gravity
Porosity
% Asphalt Content
