Bitumen Extraction Explained

Each Extraction plant is designed for a certain oil sands throughput assuming an average ore grade If an excessive amount of oil sands is processed through the Extraction plant (above the design capacity), the residence time within the gravity separation vessel is proportionally reduced and bitumen recovery rates may be compromised.

Asphalt Extraction Solvents and Asphalt Wash Solvents

Asphalt Extraction Solvents and Asphalt Wash Solvents Page 2 of 3 ⦁ All asphalt extraction solvents shall meet the following requirements of a terpene as stated in AASHTO T 164: “Extractant shall be non-halogenated, non-toxic and shall readily dissolve asphalt cement from.

US5053118A

The composition of asphalt pavements can be determined through bitument extraction, employing an alicyclic hydrocarbon as extractant under subcritical conditions For example, cyclohexane is so employed in conjunction with an apparatus hereof.

Asphalt Extraction Solvent

Like other asphalt extraction solvent solutions, EnSolv®-EX works to break down the bitumen in asphalt Bitumen serves as the binding agent that holds the asphalt aggregate material together and seals it Once that bitumen is broken down by the EnSolv®-EX solvent, the asphalt aggregate can be collected and removed.

HMA Production Manual

(Rev 2019) FOREWORD This manual is the combination of three separate Hot Mix Asphalt (HMA) manuals used in the design, production, and testing of HMA for the Michigan Department of Transportation (MDOT).

Asphalt Content Testing: Solvent Extraction vs Ignition

Solvent Extraction Solvent extraction methods have been used in the industry for many years and ASTM and AASHTO have established test methods in place These procedures use various types of solvent to separate asphalt binder from an uncompacted HMA sample.

An overview of storage and handling of asphalt

An overview of storage and handling of asphalt By Dwight Walker, PE and John Davis Long-lasting, low maintenance asphalt pavement performance begins with using an asphalt binder that has uniform properties, including consistency and temperature The manner in which the asphalt is handled and stored is critical to achieving this goal.

Developing a Laboratory Protocol for Asphalt Binder

DEVELOPING A LABORATORY PROTOCOL FOR ASPHALT BINDER RECOVERY Stacey D Diefenderfer, PhD, PE Senior Research Scientist INTRODUCTION The extraction and recovery of asphalt binders from asphalt mixtures is a relatively common laboratory procedure and is used to provide material for research and quality assurance testing.

Research

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).

Asphalt Extraction Solvent >>Reliance Specialty Products

Asphalt Extraction Solvent: EnTron-AE 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.

Binder Content

Solvent extraction methods (described in AASHTO T 164 and ASTM D 2172) use a solvent to remove asphalt binder from aggregate in an HMA mixture Asphalt binder content is then calculated by subtracting the mass of the aggregate remaining after the asphalt binder is removed from the initial mass of the test sample.

Final Report

comparing nPB extraction test results with those of TCE and toluene The 9-12 project panel is proposing revisions to AASHTO on TP2-Standard Test Method For Quantitative Extraction and Recovery of Asphalt Binder From Asphalt Mixtures to include nPB as an extraction solvent [2].
