The CoreLok® System
Our Most Versatile Testing Product.
Porosity, % Asphalt Content,Bulk Specific Gravity, Maximum Specific Gravity, & Aggregate Specific Gravity.
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.
One Machine for All your Gravity Measurements of Asphalt and Aggregate. ASTM D6752, ASTM D6857, ASTM D7063.
An accurate method for Bulk Specific Gravity measurement. Bulk Specific Gravity of Compacted Samples - Bulk Gravity Specification ASTM D6752 and AASHTO T-331.
Specific gravity (density) is the single most specified parameter in the construction industry.
For open graded mixes (i.e. SMA and OGFC) and absorptive mixtures of asphalt, the Saturated Surface Dry (SSD) method is inaccurate. Water infiltration in and out of the sample produces a lower than actual measurement for sample volume, higher calculated density and a lower estimate of air voids.
The CoreLok® system automatically seals these samples in specially designed polymer bag and allows for measurement of accurate water displacement test.
The present sealing methods, Wax and films, are labor intensive and the results are extremely operator dependent. Fully automatic sealing process.
Works with different sample sizes and shapes, 110-Volt standard operation (220-Volt optional)
Puncture resistant, easy to use polymer bags for lab and field sample testing.
Includes Water Tank, Basket, and other Accessories.
