Asphalt Production and Oil Refining – Pavement Interactive

This process of boiling and reboiling a batch of crude oil is the simplest form of refining, or distillation; it is commonly called batch distillation. However, this process of boiling off fractions of crude oil is not the most efficient way to produce petroleum products. In the 1920s, fractional distillation was developed.

The oil is subjected to atmospheric distillation followed by vacuum distillation. The nondistillable fraction from this process is the REOB/VTAE. Although REOB/VTAE have been used to modify asphalt binders since the 1980s, concerns have recently been expressed in the asphalt paving industry due to a lack of comprehensive research.
