Hot in-place recycling (HIR) is a process that preserves or maintains distressed asphalt pavements while minimizing the use of binder and aggregates. The final quality of HIR mixture depends on the characteristics of the original binder, aging during service, and new binder or the asphalt rejuvenating agent (ARA) added.
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.
Rejuvenating asphalt emulsions for surface seals and cold in place recycling Oils and emulsified oils for hot in place recycling and surface rejuvenating applications Anova rejuvenators have demonstrated desirable impact on asphalt pavements containing highly aged RAP and RAS binder (reclaimed asphalt pavement and shingles) in documented ...
• Reclamite was selected as the rejuvenating agent to be used in the laboratory on the basis of its proven record of excellent performance. Reclamite is an asphalt rejuvenator which provides maltenes to restore the asphaltenes/maltene ratio in RAP. • The effectiveness
The type of recycling or rejuvenating agent and the percentage to be added to the binder can be estimated using procedures outlined in ASTM methods D4552 (20) and D4887. (21) The recycling or rejuvenating agent, if used, should be compatible with the recycled and new asphalt …
A process which consists of softening the existing asphalt surface with heat, mechanically removing the surface material, mixing the material with a recycling agent, adding asphalt and aggregate to the material (if required), and then replacing the material on the pavement.
