13+ Asphalt Recovery Abson Method Images. The extracted asphalt can be recovered by the rotavapor method or abson method following aashto t 319 quantitative extraction and recovery of asphalt binder from asphalt mixes or. In particular, the abson recovery method was more likely to leave the residual solvent in the recovered asphalt binder, thereby lowering the measured stiffness of the recovered asphalt binder.
Subgrade Stabilization: Materials & Methods from image.slidesharecdn.com • for the ignition method, the actual asphalt content was underestimated by approximately 0.1%. Periodic renewal of the pavement surface can. Standard test method for recovery of asphalt from solution by abson method.
8.1 primary distillation, (see figure 1) 8.1.1 after centrifuging, decant the solutions from both extracted 9.3 apply a vacuum of 40 ± 0.5 mm hg below atmospheric pressure and draw approximately 600 ml of asphalt solution from the sample container.
Get contact details and address| id: Asphalt binders are complex materials that are difficult to specify and test and it has been a major effort to develop standard test methods as well as effective and meaningful specifications for asphalt binders. The asphalt is recovered with properties substantially the same as those it possessed in the bituminous mixture and in quantities sufficient for further testing. • for the ignition method, the actual asphalt content was underestimated by approximately 0.1%.
