Asphalt binder extraction and recovery are common laboratory procedures used to provide material for research and quality assurance testing. The most common methods of recovery performed today include the Abson method and the rotary evaporator (or Rotavap) method. The purpose of this study was to compare the Rotavap method proposed for use at ...

Description. The apparatus is used for the recovery of soluble bitumen from bituminous pavement materials in a form suitable for further testing. During operation, the solution of solvent and asphalt (bitumen) from a prior extraction is distilled by partially immersing the rotating distillation flask of the rotary evaporator apparatus, in a heating oil bath while the solution is …
For the recovery methods, the rotary evaporator was found to have a good reputation for relative ease of use and less binder modification than for the Abson method. The most commonly used solvents n-propyl bromide and chlorinated solvents, while being reusable, both had reported issues of ineffectiveness as well as major concerns about user ...

Jan 01, 2020 This article explains the general process to achieve the maximum possible solvent recovery rate from any rotary evaporator. Introduction Rotary evaporation is a powerful technique for quickly removing solvent from a solution of cannabis or hemp extract. There are two distinct methods of operating a rotary evaporator: batch or continuous; choosing the correct …
Jul 06, 2021 The binder was recovered from RAP using a rotary evaporator (ASTM D 5404) method. The different proportions of RAP binder (i.e., 0%, 14%, 24% and 40%) were blended with modified and unmodified binders using a high shear mixer. The preliminary tests: softening point, penetration, ductility, and elastic recovery were conducted on blended binders.

Mar 10, 2020 Both rotary evaporators and falling film evaporators are capable of distilling solvent at a relatively high throughput, but one shines through as the clear front runner. An average rotary evaporator will typically have a throughput rate of 5-10 L/hour depending on the size of the condenser and flask, vacuum level, and condensing efficiency.
need for recovery (Peterson et al., 1999). Rotary evaporator is more prefer to the Abson recovery method since subsequent researchshowed that the latter left enough residual solvent in the binder which leads to a significant reduction in binder stiffness (Peterson et al., 1999, Abson and Buton, 1960). Ma Tao et al., 2008 conducted a study with the
