Instructions for Use

Granular rejuvenator is a direct-throw asphalt recycling modifier containing high-performance polymers. The prepared asphalt mixture has excellent anti-stripping performance and low-temperature crack resistance, and pavement durability is significantly improved. It can be used for the modification of aged asphalt to enhance both high-temperature and low-temperature properties of asphalt. It is applicable to the pavement recycling of intermediate and surface courses on expressways, improving the high and low temperature performance of milled reclaimed asphalt and greatly increasing the incorporation ratio of reclaimed materials.

1. The product adopts composite modification of oily small-molecule materials and crosslinking agents, which can re-link aged and broken SBS, and replenish saturated and aromatic fractions in asphalt; 2. Significantly improve high-temperature rutting deformation resistance; 3. Improve low-temperature crack resistance; 4. Mitigate pavement fatigue damage caused by traffic loads; 5. Enhance the adhesion between asphalt and aggregates.
