The Chemical-Mineralogical Characterization of Recycled ...

Potential reactions in asphalt mixtures by nitration, sulfonation, amination of organic compounds, and reactions by alkaline activation in the aggregates were discarded due to the minimum concentration of components such as NO 2, (-SO 3 H), (-SO 2 Cl), and (Na) in the aggregates. Finally, this research concludes that studied RCAs might be used as replacements of coarse
