Asphalt Rejuvenation. Rejuvenating asphalt is the cornerstone competency on which our Company was built. We helped bring to public works professionals the original Maltene Replacement Technology (MRT). In 2017, we introduced America''s first titanium-dioxide-enriched asphalt rejuvenation product. For asphalt rejuvenation, use Reclamite®, the ...

Using a recycling agent, or rejuvenator, is one possible approach to offsetting the higher binder stiffness and improving cracking resistance of a mixture when high RAP/RAS contents are used. Objective The objective of this study was to evaluate the effect of using a rejuvenator pre-blended with a asphalt binder on laboratory-

Reclamite, a petroleum maltene-based rejuvenation agent, replaces those factions and prevents premature aging. When Reclamite is sprayed on the road, it penetrates deep into the surface to reinforce the binder that bonds the asphalt and aggregate together. Applying Reclamite to a road improves the asphalt''s durability, flexibility and ...

"This is an exciting time to be in asphalt recycling research," Dr. Amy Epps Martin said. She is a professor and the A.P. & Florence Wiley Faculty Fellow in Texas A&M''s Zachry Department of Civil Engineering. "My dad began his research career in the field of asphalt recycling …

Individual effect of aging and rejuvenator recycling on basic properties of asphalt is readily recognized, but there is only limited understanding about whether the recycling of SBS- (styrene-butadiene-styrene-) modified asphalt is an inverse process of aging or not. To compare the effects of aging and rejuvenator on microproperties and molecular composition of SBS-modified asphalt ...

Recycling Agents (rejuvenators) Three types of recycling agents were used to restore the old binder to the AC-20 classification range. Selection of the three types was based on their previous usage in recycling techniques other than hot-mix recycling. In addition, the AC-20 classifica­ tion range was a target because AC-20 is widely used in

etary recycling agents made from bio-based oils have been marketed and sold as rejuvenating agents," say NCAT''s Tran. "A true rejuvenator changes what''s underneath, by replacing missing maltene oils and resins," Durante said. "Most of the bio-based materials are composed of various diluents derived from agricultural sources.

 · In recycling mixture with high RAP content a rejuvenator is usually used. The recycling of reclaimed asphalt pavement is usually achieved by adding a rejuvenating agent into the aged pavement mix . Rejuvenators are sometimes referred to as softening additives or recycling agents,, though, as it was

project no. 9-58 copy no.__ the effects of recycling agents on asphalt mixtures with high ras and rap binder ratios phase ii revised interim report

The project began in winter 2019 with a callout for asphalt rejuvenator—or recycling agent—suppliers to participate if they wished. Anderson Brothers calculated the cost of performing the changes to the job and those costs were split evenly among the seven rejuvenator suppliers who elected to participate.

Bituminous recycling agents are required and consist of foamed asphalt or emulsified asphalt. Chemical additives, such as cement may be used in addition to the recycling agent to improve early strength gain and resistance to moisture induced damage. ... while engineered emulsions with a rejuvenator can potentially soften old, aged binder. A ...

They work in two separate ways: Revive rejuvenators 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. Revive rejuvenators reduce the complex shear modulus of the resulting RAP- asphalt binder mixture.

 · 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 (ITS) of samples as well as …

 · The downsides to recycling agents, in particular, have traditionally been cost and availability. As an alternative to bumping the grade of the binder, most current rejuvenators work by injecting lighter maltene-rich material—saturates, aromatics, and resins—into the RAP binder that has become rich in the heavy asphaltenes due to oxidation.

Recycling Agents. 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 high RAP binder and repair the oxidative aging.

current practice. When used at the plant, a rejuvenator delivers the same softening as different PG binders but with far fewer products and storage tanks. Multiple tanks containing different PG binders can be replaced by a single tank and a single rejuvenator. This approach is suitable for all levels of recycling right up to recycled content.
