Asphalt Extraction Solvent Solutions EnSolv®EX is an azeotropic mixture specifically blended for granular and bituminous extractions and is ideal for use in a variety of asphalt extraction methods. EnSolv®EX is an excellent choice as a replacement for methylene chloride and trichloroethylene for all extraction processes and does not require ...
AutoXtract™ Automatic Asphalt Extraction System ASTM D8159 The AutoXtract™ is an innovative device that automates the processes associated with asphalt extraction and recovery. The unit has been designed for the determination of asphalt content in mixtures as well as the characterization of reclaimed asphalt pavement (RAP) properties.
First, Some Information About the Asphalt Extraction Process. A material called bitumen, which is a black viscous liquid used in roofing and road surfacing, is broken down during asphalt removal so that it can no longer bind and seal the asphalt aggregate material together.
Max. quantity of asphalt per extraction: 3.5 kg. Max. quantity of filler: 300-400 g. Time required for a complete extraction: from 25 to 45 min. Max. solvent recovery capacity: from 40 to 50 l/h. Rotating speed: 12000 r.p.m. Current specifications: 220-380 V, 50-60 Hz, 3 ph., 3.5 kW. Overall dimensions of the testing unit: 1200x650x1200 mm approx.

Asphalt Extraction Solvents are non-toxic and biodegradable for use in vacuum or centrifuge extractors for graduations. For more information on Asphalt Binder Extraction Test Equipment, here are our related blogs: Asphalt Content Testing: Solvent Extraction vs …
ASTM D2172 Extraction Procedures • Section 3: "Summary of Test Methods" – The asphalt mixture is extracted with trichloroethylene (TCE), normal propyl bromide (nPb), or methylene chloride using the extraction equipment applicable to the particular method. – The asphalt …
The asphalt binder content is calculated by differences from the mass of the extracted aggregate and moisture content, and mineral matter in the extract (when using centrifuge extraction from Test Method A and when using the automated extraction in Method F . The asphalt binder content is expressed as a mass percent of moisture-free mixtures.
original sample, it will appear as asphalt cement in the final calculation unless a correction is made. This is done by determining the amount of moisture in a separate 1000 g portion and adjusting the mass of the extraction test portion or, if time permits, heating the extraction test portion to a constant dry mass.
Safely replace Trichloroethylene (TCE) and Methylene Chloride for asphalt extraction with EnTron™-AE. EnTron™-AE is an n-propyl bromide (nPB) based solvent which is safer to use and more environmentally friendly then the chlorinated solvents typically used in asphalt extraction applications.
This study compares the results of four asphalt extraction methods: the Quick (WSDOT 711), the Vacuum (AASHTO T-164 Method E-11), the Centrifuge (AASHTO T-164 Method A), and the Reflux (AASHTO T-164 Method D). The methods are compared on the basis of the amounts of trichloroethane used, the exposure to trichloroethane while testing, the time ...
Asphalt Content Testing: Solvent Extraction vs Ignition Furnace (Infographic) When paving with Hot Mix Asphalt (HMA) it's important that the properties of the material being laid down match what is called for in the mix design. One of the most basic factors to test for is the asphalt content of the material. There are two popular options to ...
extraction), and method B (reflux extraction), asphalt analyzer as well as AASHTO T 308. A total of eight mixes, including mixes and mixes with various contents of recycled binder, were evaluated to quantify the variability in the determination of their asphalt content. In
