Laboratory Performance of Asphalt Mixtures Containing Recycled Asphalt Shingles, Reclaimed Asphalt Pavement, and Recycling Agents

Journal of Materials in Civil Engineering, 2017
AbstractAs the price of liquid asphalt continuously climbs, methods are being sought to decrease material costs without compromising material or pavement performance while having a positive influence on sustainability. One potential method is the use of recycled materials, such as recycled asphalt shingles (RAS) and reclaimed asphalt pavements (RAP ...

Supercritical Fractions as Asphalt Recycling Agents and Preliminary Aging Studies on Recycled Asphalts

Industrial & Engineering Chemistry Research, 1997
Several asphalts were fractionated using supercritical pentane. These fractions were analyzed by gel permeation chromatography and high-performance liquid chromatography, and their viscosities were measured. The properties of these fractions vary not only among the fractions of a given asphalt but also for the same fraction produced from different ...
