CoreLok® - One Machine for All your Gravity Measurements

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.

• Does Not include Bags.
