An innovative, non-nuclear method of determining SuperPave, Stone Matrix (SMA), and coarse mix asphalt air voids. CoreLok performs 5 standard lab tests:
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.
ASTM D6752, ASTM D6857, ASTM D7063. A fundamental density measurement. It does not require empirical calibrations. An accurate method for Bulk Specific Gravity measurement.
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 a specially designed polymer bag and allows for the measurement of accurate water displacement tests. The present sealing methods, Wax and films, are labor-intensive and the results are extremely operator-dependent. Click this link for the Bulk Gravity instructional video.
This method may be used as an alternative to the conventional “Rice Test” for the determination of maximum specific gravity of loose asphalt mixtures. The CoreLok® test can be completed in seven minutes with minimal exposure to water, eliminating the need for a lengthy “Dry Back” method.
This procedure requires that a sample of dry asphalt mixture is placed inside the vacuum bags and sealed within the CoreLok® vacuum chamber. The bags are then cut open underwater and a submerged weight is determined. The weight in air and the submerged weight can be used to calculate the maximum specific gravity of the asphalt mixture.
Oven dry aggregates are used in this test to determine the specific gravity and absorption of fine or coarse aggregates in less than 20 minutes. This test is highly accurate and repeatable.
In this test, density measurement is obtained by fully saturating the sample with CoreLok® and another density is measured under an unsaturated condition. These two densities can be used with already known equations to calculate apparent specific gravity, absorption, and bulk specific gravity. The AggSpec™ PC software allows for simple entry and calculation of these parameters.
Porosity is the measure of the percentage of water-permeable voids in a compacted sample. Porosity gives an accurate estimate of sample permeability. You can now determine the interconnectivity of voids within your sample and determine your mix performance during design or after lay down. Two different mixes with 7% air voids can have different permeability performances on the field, depending on the interconnectivity of voids. However, these same mixes will never have the same porosity. For open-graded mixes, Porosity is a more meaningful measure of performance than % air voids. GravitySuite™ software included with CoreLok® provides automatic calculation of porosity based on a sealed and unsealed density of your sample.
Use the CoreLok® to get an accurate measure of percent asphalt. The measurements using the CoreLok®, involves the determination of gravity of combined aggregate, only available with the CoreLok® unit, and maximum gravity of your mixture. These two critical measurements of your mixture can be used with the standard Superpave™ equations to accurately calculate the %AC in your mixture. This method is unique and very accurate for the determination of %AC for difficult aggregates with significant variability and breakdown in the NCAT ignition furnace. The CoreLok® method is simple and can be completed in less than 20 minutes.

PaveScan Mix Design Module (MDM), is an innovative system used to create a correlation between the dielectric value of the mix and the asphalt density at different percent air voids. This correlation can then be entered into the PaveScan, Non-nuclear Rolling Density Measurement System (RDM), and used as a powerful QC/QA tool for accurate density measurements of the entire asphalt pavement. Quality process control using PaveScan MDM and RDM means all pavements and longitudinal joints can be compacted to specification in real-time.
The InstroTek PaveScan Powered by GSSI Technology is the first non-nuclear rolling density system that provides real-time compaction and density data for the entire paving project. Proper compaction is the most important factor in producing long-lasting pavements. The PaveScan uses multiple sensors to continuously scan the entire pavement and provide a density profile of the entire paving project. The operator pushes the cart along the lane and gathers density data behind the asphalt rollers. The onboard computer displays density, compaction, a line graph, and a contour map of the measurements. This information is used by contractors and pavement engineers to assess the quality of the pavement.
The Smart-Jig is a completely independent testing jig with the first integrated load cell, electronics, and Bluetooth connectivity that makes capturing, reporting, and sharing data seamlessly.
InstroTek’s SmartLoader is a variable speed universal load frame that can perform a multitude of monotonic loading tests. The SmartLoader is perfect for Balanced Mix Design (BMD) testing and comes preprogrammed with a number of BMD tests, including IDEAL-CT (Cracking Test), IDEAL-RT (Rutting Test), IFIT, and LSU SCB test.
The Ignition Panel™ is a front panel upgrade for the NCAT Asphalt Content furnace. The NCAT Furnace is widely used in the asphalt industry for accurate determination of asphalt content and quality control of pavements.

In less than 30 minutes, the CoreDry eDry Emulsion Kit can be used to dry up to 5 grams of asphalt emulsions. CoreDry’s patented vacuum technology allows pavement engineers to quickly determine the appropriate binder content and application rates while retaining the rheological properties of the binder.
The Asphalt Roller Compactor (ARC), now available through InstroTek, Inc., is the first unit developed based entirely on an electro-mechanical system. The compactor does not require hydraulic fluids or air pressure, which allows the users to produce repeatable and consistent samples. The asphalt slab produced with this compactor is much more representative; with aggregate orientation similar to samples compacted in the field.
The Asphalt Compatibility Tester (ACT) is a fast, straightforward method to evaluate the adhesion properties of asphalt binder and aggregates in the mixture. This test uses LED light and detection system to measure the color change that may occur as a result of ASTM D 3625 (Boil Test Method).
