MicroEncapsulation of Asphalt Rejuvenators using Melamine

Micro-encapsulation of asphalt rejuvenators using melamine ...

01/07/2016  Highlights. This study evaluated the efficiency of the rejuvenator, a heavy resin, to reverse the aging process on asphalt binders and to develop the synthesis procedure for the production of microencapsulation of asphalt rejuvenators. The rejuvenator partially restored the aged binder for binder PG 70-22 and binder PG 76-22.
