Effects of asphalt rejuvenator on thermal and mechanical properties of oxidized hot mixed asphalt
The utilization of asphalt rejuvenator, and its effectiveness for restoring thermal and mechanical properties was investigated via Disk-shaped Compact Tension (DC(T)) testing and acoustic emission (AE) testing for determining the embrittlement temperature of the mixtures. During the DC(T) testing …

Quantitative evaluation of low-temperature performance of sustainable asphalt mixtures and binders containing recycled asphalt shingles (RAS) and rejuvenators
… and to investigate the effectiveness of rejuvenators on restoring any loss in said performance. The study was subdivided into three parts. Part 1 of the study examined HMA mixtures that contained varying amounts of RAS (0.0%, 2.5%, 5.0%, 7.5%, 10.0%, and 12.5% by weight of the total …

Quantitative evaluation of rejuvenators to restore embrittlement temperatures in oxidized asphalt mixtures using acoustic emission source location techniques
Asphalt rejuvenator was designed to be an asphalt additive to revitalize, provide sealing and restore the properties of aged asphalt concrete. Its penetration depth into asphalt concrete, and its ability of restoring asphalt's embrittlement temperature was quantitatively investigated in this study …

The effectiveness of actively accumulating dust in rejuvenating soils and ecosystems in a super-humid, high weathering and leaching environment, West Coast, South Island, New Zealand
… cycles. Dust is recognised as an important rejuvenator by supplying nutrients and unweathered mineral material to ecosystems. While deposition rates have been regularly quantified for terrestrial environments in the past, the rejuvenating effect of dust on soils and terrestrial ecosystems …

Optimizing the Use of Reclaimed Asphalt Pavement (RAP) in Hot Mix Asphalt Surface Mixes
… contents, the use of a WMA additive, and a rejuvenator. To analyze the mixes' performance in great depth, a three-level (base, intermediate, and advanced) testing framework was defined. Each level was characterized by an increasing degree of complexity and included tests to characterize both …

Laboratory characterization and field performance of hot in-place recycled mixtures
… 50 mm thickness was milled and recycled with a rejuvenator followed by a 38 mm thick AC overlay. Field investigation comprised of Falling Weight Deflectometer (FWD), profiling for predicting International Roughness Index (IRI) and Condition Rating Survey (CRS). FWD was conducted at every 61 m …

An analysis of impact factors on the Illinois flexibility index test
The use of recycled materials in asphalt pavements has become widespread in recent years. Materials such as recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) have been incorporated into the material design of typical pavements. The use of these materials is both economically and …
