“…To evaluate the rheological behaviors of PPA-modified asphalts, two rheological parameters were selected, namely the percent recovery R and non-recoverable creep compliance Jnr. Binders with a higher value of R and a lower value of Jnr are expected to have better rutting resistance [51]. The percent recovery rates R of 5% SBS-and PPA-modified asphalt binders under 0.1 kPa and at various temperatures are illustrated in Figs.…”

“…Lavin and baker et al 2003 (86) while evaluating to improve the quality of asphalt pavements, the asphalt industries developed PMA to help to meet the demand for better pavements and to influence better pavement performance under high traffic applications. Polymer modifications are becoming important factors in paving industry due to their proven effects such as better resistance to rutting fatigue damage, stripping and thermal cracking in asphalt pavements of polymer modifiers, Styrene Butadiene Styrene (SBS) originally developed by Shell Chemicals co, is widely used in majority of the asphalt binders industry and probably the most appropriate polymer for asphalt modification, SBS creates three dimensional network within virgin asphalt resulting in excellent bending strength to aggregates which lead to a durable and long lasting pavements.…”

With increasing concerns of global warming and increasing exhausation of gases, the asphalt industry looking for alternative for hot mix asphalt (HMA). Warm mix asphalt (WMA) is a fast emerging new technology which has a potential of revolutionalizing the production of asphalt mixtures. WMA technology allows the mixing, lay down and compaction of asphalt mixes at significantly lower temperatures compared to hot mix asphalt (HMA). The technology can reduce production temperatures by as much as 30 percent. Asphalt mixes are generally produced at 150°C or greater temperatures depending mainly on type of binder used. WMA mixes can be produced at temperatures of about 120°C or lower. In this study an attempt has been made to compare HMA (VG-30 and WMA (SBS-PMB-40) with organic additives (Zycotherm, Sasobit and Evotherm) with various dosages on Marshall properties for Dense Bituminous Macadam (DBM), Grade-2. the adopted mixing temperatures for HMA was 155°C, 130°C, and 120°C and mixing temperature for WMA was 130°C and 120°C. The laboratory study concludes that stability and Marshall properties for WMA mix were improved by addition of additives.

With the development of pavement recycling technology, the requirement of reclaimed asphalt pavement (RAP) is substantially increasing. Warm-mix recycled asphalt (WMRA) technology has made great progress, which can effectively decrease the working temperature and improve the RAP content. In this study, the rheological properties of recycled binders with incorporation of high-percentage artificial RAP binder (30–70%) were evaluated using two types of warm-mix asphalt (WMA) additives, i.e., polyethylene wax R and surfactant M. The dynamic shear rheometer (DSR) and beam bending rheometer (BBR) tests were conducted on the recycled binders. The results showed that the temperature and frequency played an important role in determining the complex shear modulus of the high-percentage WMRA binders. The dependency of phase angle on frequency increased after the long-term aging. The WMA additive R had a relatively huge impact on the rheological properties of asphalt, which mainly occurred before the PAV aging of recycled asphalt binder; the WMA additive M had no significant impact on the rheological properties of recycled asphalt binder. The WMA additive R enhanced the low-temperature rheology of recycled asphalt binder, while the WMA additive M enhanced the high-temperature rheology of recycled asphalt binder. Both of these types of WMA additives improved the antifatigue performance of recycled asphalt binder. The increased content of RAP binder improved the high-temperature performance and reduced the low-temperature performance of the recycled asphalt binder. However, it had no obvious impact on the fatigue performance. In addition, there was a good linear relation between the RAP binder content and the two indexes of the multiple stress creep recovery (MSCR) test.
