The use of rejuvenating agents in production of

To overcome this problem, rejuvenating agent or rejuvenator is usually used to restore the RAP binder properties to a condition that resembles that of fresh asphalt binder. Different types of rejuvenators have been used previously. This study provides an overview on utilizing RAP, and the use of rejuvenators, type and dosage, in production of

Effects of Rejuvenating Agents on Superpave Mixtures

Rejuvenator is not a commonly used softening agent to be used in recycling of reclaimed asphalt pavement (RAP). In this study, Superpave mixtures containing RAP were designed using rejuvenating agents, including a rejuvenator and a softer binder, and subsequently evaluated in terms of the volumetric results, obtained the indirect tensile strength

Determining optimum rejuvenator dose for asphalt

2014-10-30  The maximum rejuvenator dose should be calculated to pass the targeted high PG temperature according to Eq. . The minimum rejuvenator dose should be calculated to ensure the required low PG temperature according to Eq. and intermediate PG requirement according to Eq. . The higher of the two should be defined as the minimum.
