Gilson Asphalt Content Furnace (HM-378)

The Gilson HM-378 Asphalt Content Furnace provides a simple and economical method for determining asphalt binder content in hot-mix asphalt (HMA) samples. In this video, see how the HM-378 Asphalt Content Furnace is used for asphalt content testing by heating HMA samples until the asphalt binder is burned away, leaving the aggregate for final weight determination and further testing. The manually operated system offers accurate asphalt content results and can process typical samples in approximately 30–45 minutes. The HM-378 is designed for asphalt testing laboratories performing binder content determination, asphalt mix design, and quality control testing. It meets ASTM D6307 and AASHTO T 308 requirements for asphalt content by ignition.

Standard Test Method to Determine of Resistance to Degradation of Small Size Aggregate. (HM-70A)

The Gilson HM-70A Los Angeles Abrasion Machine is used to evaluate the toughness and abrasion resistance of coarse aggregate. This video demonstrates the Los Angeles (LA) Abrasion Test for determining the resistance of small-size coarse aggregate to degradation from abrasion and impact. During testing, an aggregate sample and hardened steel abrasive charge are rotated inside the machine’s steel drum, subjecting the material to repeated impact and abrasion. The resulting material loss is used to evaluate aggregate durability and quality. The HM-70A Los Angeles Abrasion Machine is designed for aggregate testing in construction materials laboratories and meets requirements for ASTM C131 and AASHTO T 96 testing.

Gilson Concrete Air Meter with Digital Gauge Cannister Method CALIBRATION (HM-30D)

Proper calibration helps ensure accurate and reliable concrete air content testing. This video demonstrates the canister method for calibrating the Gilson HM-30D Concrete Air Meter with Digital Gauge. The HM-30D is a Type B pressure air meter used to determine the air content of fresh concrete. Follow along with the calibration procedure to verify the digital gauge and prepare the air meter for accurate concrete testing in the laboratory or field. The Gilson HM-30D features a digital pressure gauge with a backlit display for clear, easy-to-read air content measurements.

How to Evaluate the Workability of Slip Form Concrete Paving with the Box Test (HM-592)

The Concrete Box Test provides a quick method for evaluating the workability of slip-form concrete used in paving applications. In this video, learn how to perform the Box Test to determine whether a concrete paving mixture can properly consolidate under vibration while maintaining enough stability to hold its shape after the form is removed. The finished specimen is evaluated for edge slumping and surface voids, helping identify potential problems with concrete mixture proportions and consolidation. The Gilson HM-592 Slip Form Concrete Box Test Device provides a simple, portable setup for evaluating fresh concrete mixtures used in slip-form paving applications.

Gilson Los Angeles Abrasion Machine (HM-70A)

The Gilson HM-70A Los Angeles Abrasion Machine is designed to evaluate the abrasion resistance, toughness, and durability of mineral aggregates. In this video, explore the features and operation of the HM-70A and see how the machine subjects aggregate samples to repeated abrasion, impact, and grinding inside a rotating steel drum. The resulting percentage of material loss provides an indication of aggregate quality and resistance to degradation. The HM-70A features an enclosed design, electronic safety interlocks, a programmable revolution counter, and a powerful drive system for reliable Los Angeles Abrasion testing. It is designed for aggregate testing applications in construction materials laboratories.
