Advantages

Light oil and heavy oil fractions both show great potential as aged asphalt rejuvenators in terms of rheological properties and microscopic characteristics

Waxy components can be used for asphalt thermoregulation after hydrolysis

Waxy components can be used as warm mix asphalt additives after ammonolysis

Conducive to reducing energy consumption and VOC emissions during construction
