Cold In-Place Recycling (CIR) uses a train of equipment that mills, screens, and crushes the existing asphalt pavement. Typically 3-5 inches is milled off of the pavement. An asphalt rejuvenating material is then blended with the reclaimed material and the recycled mix is laid back down to form a new pavement structure.
Hydrolene™ Hot MixAsphalt Rejuvenation. These are the oils that make asphalt better than new. They actually reconstitute the original chemistry of the asphalt or RAP, adding back the elements that have been lost through oxidation and aging. This results in roadways that defy comparison for …
Aug 04, 2021· By adding approx 1-2 litres of rejuvenating oil or 1kg of rejuvenating wax (depending on proven binder content) to 1 tonne of old or contaminated asphalt will replace oils that have dissipated or oxidised from its original form reversing the aging effect. Rejuvenating Oil …
Patent # 5,180,428. This emulsion shall contain asphalt, a recycling agent, and a polymer. The asphalt must be manufactured from crude oil from Ventura County CA or as required by the manufacturer. The recycling agent must be RA-1 manufactured by San Joaquin Refining or Tricor Refining as required by the manufacturer. The
Rejuvenating agent may be added to the hot millings if needed. Surface recycling can only rehabilitate the top inch of pavement and is often followed by an HMA or bituminous surface treatment (BST) overlay. The remixing process is similar to surface recycling with the advantage that improvement
A Rejuvenating Scrub Seal is an application of a rejuvenating asphalt emulsion scrubbed into the cracks and voids, followed by an application of aggregate ... Oil Distillate, % T59 0.5 Sieve Test, % T59 0.1 Residue by Distillation(1) ... samples of the recycling agent being used in manufacturing of emulsion delivered to the project.
Rejuvenating seals are a combination of various chemicals or a mixture of asphalt emulsion and recycling agents applied to the asphalt pavement surface. There are a variety of rejuvenating seals used in California. Rejuvenating emulsions (e.g. Reclamite (oil emulsion), PASS (asphalt, oil and

Mar 15, 2021· A commercial asphalt rejuvenator (based on mineral oil, referred to as M) and two developed rejuvenators (based on corn oil, referred to as C, based on soybean oil, referred to as S) were added into the aged asphalt according to the weight ratio of 2–10%, the regeneration process was shown in Figure 2. The regeneration temperature was 135°C ...
Jul 12, 2021· That is, asphalt started out as a byproduct of crude oil, then became shingles, which became roofs, only to eventually be torn off and sent to a landfill — removed from the roofing economy. The new GAF RAS process opens the door to eventually creating a circular, sustainable economy in which most of that asphalt remains in use as new shingles.
Dec 15, 2017· Adding specially designed rejuvenating additives to mixes containing RAP leads to better performance than more traditional measures of adding bitumen or flux oils, according to research detailed in a paper by asphalt additive specialist 252 Iterchimica "When it comes to the recycling and reuse of RAP, flux oils are often considered at the same level as rejuvenating additives, but this ...
Jul 01, 2016· 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 [57], [58], though, as it was described earlier a difference is made between the asphalt rejuvenating and softening agents.
Cyclogen® recycling oils are specifically designed to rejuvenate aged asphalt pavement (RAP). These engineered oils provide a one component system available in 2 grades for hot in place recycling and fixed plant recycling – Cyclogen® L and M and 2 emulsified cationic grades – Cyclogen® LE and ME for cold in place, pugmill mix or lay and spray recycling applications.
