How to Use Asphalt Rejuvenator

Asphalt rejuvenator is mainly used in hot recycling of reclaimed asphalt pavement (RAP) to restore the performance of aged asphalt binder. It can be applied in both plant hot recycling and in-place hot recycling projects for highways, municipal roads, and airport pavements.

Step 1: Determine the Rejuvenator Dosage

The recommended dosage of Go Green Asphalt Rejuvenator is generally 0.2%-0.35% of the milled RAP material. The actual dosage should be determined through laboratory testing according to the aging condition and RAP content.

For reference, when the RAP contains approximately 50% reclaimed material, a dosage of around 0.25% of the milled material can be used as a starting point for mix design.

Step 2: Heat the Asphalt Rejuvenator

For direct spraying, heat the rejuvenator to approximately 80-130℃.Heating helps improve its flow, dispersion, and penetration into the aged asphalt material.

Step 3: Add the Rejuvenator

There are two common methods:

Method 1: Direct Spraying

Use dedicated rejuvenator spraying and metering equipment to spray the heated rejuvenator uniformly onto the heated RAP material. The treated RAP is then mixed with new aggregate and new asphalt in the mixing drum.

Because the dosage is relatively small, precise metering equipment is recommended to ensure uniform distribution.

Method 2: Pre-Mixing with New Asphalt

The rejuvenator can also be blended with the required amount of new asphalt in a dedicated asphalt blending tank.

Maintain the asphalt at its normal insulation temperature and mix the rejuvenator and new asphalt thoroughly by mechanical stirring or by circulating the asphalt through the pump 2-3 times. This method provides more consistent dosing and is easier to control during production.

Step 4: Mix with RAP and New Materials

After the rejuvenator has been added, combine the treated RAP with the required amount of new aggregate and new asphalt according to the approved mix design. Mix thoroughly to ensure the rejuvenator is evenly distributed throughout the recycled asphalt mixture.
