Asphalt Mix Design Equipment
The Gilson HM-8 Vacuum Extractor with 3,000g capacity has superior design features for quantitative determination of bitumen in hot-mix asphalt paving mixtures using the vacuum method. The Extractor base is a 16in (407mm) dia. x 8in (203mm) high painted aluminum extract collection tank with carrying handles, a gauge-fitted vacuum source connection and an extract drain valve. Two sight-glass gauges are provided to monitor solvent level and color of extract during extraction. A removable funnel ring clamps filter paper and a perforated aluminum support plate to base with a Viton O-Ring seal. Sample and solvent are placed on paper inside the ring.
Improved design features anodized aluminum funnel ring for protection from corrosive solvents. Quick-action wing bolt fasteners between ring and base have no exposed threads to damage. Filter paper support plate has disk spacers to prevent collapse under vacuum.
The HM-8 Vacuum Extractor includes a Vacuum Gauge, 25 Filter Papers, Filter Support, O-Ring Seal, 4ft (1.2m) Vacuum Hose Connection, and instructions. For best results we recommend using biodegradable terpene-based solvents and HMA-54-2 filter papers. Vacuum source is required.
