Asphalt oxidation is of pragmatic importance because it leads to the hardening of the asphalt, resulting in a deterioration of desirable physical properties. In asphalt pavements, oxidative age hardening contributes significantly to pavement embrittlement, eventually resulting in excessive pavement cracking.
on fine mix asphalt pavements, where aggregate is polished, or if there is an oily film throughout the pavement. May be used as a primer for new as-phalt patches.

There are several asphalt patching techniques that may be used for filling cracks, pothole repairs in roads, pavements, parking lots, playgrounds, tennis courts, etc. When done the right way, patching helps prevent further deterioration and avoid huge repair expenses. Materials used may range from hot mix asphalt, to asphalt emulsion mixes and proprietary patching mixes …
After the oxidation/stirring-time has expired and the methcathinone is in solution ready to be extracted, before adding 25% NaOH, add about five milliliters of isopropylalcohol (store bought of any concentration is fine, exact measurements not really needed [ballpark figure is fine]) to the mix.
