Asphalt Rejuvenators for Recycled Asphalt Pavement

Asphalt pavement is one of America’s most recycled products. Recycled asphalt pavement (RAP) can be of extremely high quality containing Class 1 aggregates as well as oxidized asphalt. Recovering these resources can be extremely valuable to the taxpayer. Recycling and reusing this valuable resource can significantly reduce the cost of a ton of hot mix, but the oxidized asphalt in RAP has a stiffening effect on the mix. Excessive quantities of a stiff binder can lead to reduced pavement flexibility, early cracking and premature failure.

Arkema-Road Science has developed the Revive® and Cecabase® RWI lines of asphalt rejuvenators to specifically address these issues. Revive and Cecabase RWI rejuvenators facilitate significantly increased RAP usage while maintaining mix flexibility and controlling stiffness. They work in two separate ways:

  1. They have a high solvency for the old, aged and oxidized asphalt. This means a very high percentage of the RAP binder will be quickly accessed and brought into the binder / mastic continuum.
  2. They reduce the complex shear modulus of the resulting RAP-Virgin asphalt binder mixture. This combination reduces the risk of undesired performance and enables profitable use of more RAP.

Adding an additional 20% RAP to a 15% RAP mix will allow you to reduce your virgin binder demand by almost 40%. With Arkema-Road Science’s Revive and Cecabase RWI rejuvenators, these results can be effectively achieved without compromising the quality and long-term durability of the mix.

Arkema-Road Science has developed a free Guide to Evaluating RAP Rejuvenators which provides guidance on:

  • How to effectively evaluate RAP rejuvenators.
  • (8) key questions to ask your rejuvenator supplier to avoid high-RAP mix challenges.
  • Tests that can be used to predict RAP rejuvenator durability and performance both in the lab and in the field.
  • How to determine whether a RAP rejuvenator will truly help increase RAP usage and improve high-RAP mix performance long-term.
