· Rejuvenators are sometimes referred to as softening additives or recycling agents , , though, as it was described earlier a difference is made between the asphalt rejuvenating and softening agents. While the softening agent is used to lower the viscosity of asphalt binder, the rejuvenating agent restores the Asphaltene/Maltene ratio [42] , [59] .
A rejuvenating agent having a viscosity of from 200 to 60000 cSt at 60° C. and comprising 10-90 weight % palm oil and 90-10 weight % bitumen, where the percentages are based upon the total weight of the composition, is disclosed. The rejuvenating agent is suitable for use in hot in-place and hot in-plant recycling processes.

· Laboratory Performance of Asphalt Mixtures Containing Recycled Asphalt Shingles, Reclaimed Asphalt Pavement, and Recycling Agents Journal of Materials in Civil Engineering June 2016 Performance of Asphalt Mixtures with High Recycled Contents Using Rejuvenators and Warm-Mix Additive: Field and Lab Experiments
· In this study, four different rejuvenating agents were selected to rejuvenate reclaimed aged binder and produce recycled asphalt mixtures incorporating 60% of RAP. Related pavement properties, including rheological properties of rejuvenated binders and dynamic response behavior of recycled asphalt mixtures, were characterized in order to guide .
Recycling agents used in this study could improve fatigue and intermediate-temperature cracking performance of the mixtures depending on the RAP content and testing conditions.
A recycling agent is used to soften and rejuvenate the existing asphalt pavement. Pavement is the top layer of roadway, and is made of portland cement concrete (PCC) or AC. The pavement is supported by the base and sub-base, which consist of aggregate and other materials.
Anova asphalt pavement rejuvenator is a bio-based additive shown to reverse the impact of aging in RAP and RAS binder applications. Call 1-800-842-3631.
At the optimum content of the asphalt and asphalt of 0.5 percent below and above the optimum value, specimens were prepared by using Marshall Method. Two types of polymers as recycling agents were used (Polyethylene of Low Density and Crumb Rubber) with (0.5, 1 and 1.5) % by weight of the binder.

Recycling Agents are also capable of reducing the viscosity and improving the low temperature properties of the high RAP binder. Here’s where they differ from a rejuvenating agent: A recycling agent does not add the aromatic resins to balance the properties of …
The range of recycling methods demands several emulsified recycling agents. The groups should provide adequate freedom of selection for most recycling methods. 3.2.1 ER-1 is a material whose main function is to rejuvenate aged asphalt.

City is heat scarification, which is a hot- in-place recycling of the existing asphalt. This process consists of heating and scarifying (lifting) the existing asphalt, adding a rejuvenate agent and repaving the recycled mix. The City has been using this technique for five years and has scarified approximately 1.5 million square yards of
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.
OptiPave is a Ready-To-Use mineral stabilized Asphalt Emulsion. Simply Stir and Apply. OptiPave is an asphalt-based emulsion pavement surface seal designed to seal and protect asphalt roads while replenishing the pavement binder that is lost through oxidation and weathering.
This material is crushed and screened to the proper size and recycling agents are mixed in to rejuvenate it and give it more life. If necessary, virgin aggregate can be added and spread on the existing surface. Recycling agents that are used include: emulsified asphalt, foamed asphalt, and …
Reclamite ® 1 asphalt rejuvenator is the original Maltene Replacement Technology (MRT) for restoring and preserving the durability of asphalt. Based on the innovative research of Witco Corporation’s Fritz Rostler, Reclamite rejuvenator restores the reactive maltene components that asphalt pavements lose due to hot-plant operations and the subsequent field aging process, penetrating the .
containing RAP: rejuvenating agents and softening agents. The primary difference between a softening agent and a rejuvenating agent is that a rejuvenating agent will restore the chemical structure of the binder [1]. In either case, recycling agents are usually made
The HP-GPC analysis for the virgin and recycled asphalt binders may be recommended as a criterion for the choice of the proper amount and characteristics of a recycling agent to be used to rejuvenate salvaged asphalt.
· Studies on rejuvenation of aged binders recommend that it is possible to use higher percentage of RAP by using recycling agents or rejuvenators. . soften and rejuvenate the aged asphalt where 1% .
of a recycling agent to be used to rejuvenate salvaged asphalt. Asphalt is considered a combination of asphaltenes, resins, and oils. Many other fractional classifications have been reported about asphalt composition. However, this classifi cation is still considered the simplest and most understandable one.
On the day of the treatment, any dirt or foreign material should be removed from the pavement surface by sweeping, or by the use of compressed air, before applying the rejuvenation agent.
