Thermo-rheological analysis of WMA-additive modified
Thermo-rheological characteristics of unmodified and modified bitumen have significant impacts on the mechanical response of asphalt. This study investigates the impacts of an organic and a chemical Warm Mix Asphalt additive on bitumen thermo-rheological and mechanical characteristics. Modified binders with different concentrations Reclaimed Asphalt Pavement (RAP) is often used with Warm Mix Asphalt (WMA) additive to reduce the production temperature and limit emission at the asphalt plant and worksite. Despite sustainable utilization of RAP, the long-term performance of recycled mix is still quite concerning, and thus research focus on the risk of premature pavement Synergistic Effect of Hydrated Lime and Warm Mix Asphalt Additive

The current study aims to examine the physical and rheological properties at the high-temperature range of 52, 58, 64, 70, 76, and 82°C, utilizing adjusted asphalt binders. Three kinds of asphalt modifiers were selected such as styrene-butadiene-styrene, ethylene vinyl acetate, and end of life tires. The selected additives were implemented Salt-storage additives (SSAs) were added to the asphalt mixtures during the construction stage, and the formed anti-icing asphalt pavement (AIAP) played an active and smart role in continuous snow melting, which could avoid traffic accidents and provide positive support for winter road maintenance in cold areas.

Polymers Free Full-Text Effect of a New Additive Based on
Stone Mastic Asphalts (SMA) are asphalt mixes with discontinuous granulometry and a high content of asphalt binder. In order to prevent draindown of the asphalt binder and ensure good performance, these mixes must be strengthened with cellulose or mineral fibres and/or polymer additives. This study was designed to evaluate A later study in Indiana compared the field performance of seven asphalt additives or modifiers. In this case, polyester fibers were used in an asphalt overlay over jointed concrete pavement. The fibers were 6.35 mm long, added at a rate of 0.3% by weight of the mix, and dry mixed for 30 s, then wet mixed for 35 s in a batch plant.Read "Fiber Additives in Asphalt Mixtures" at NAP.edu

Use of amorphous-poly-alpha-olefin as an additive to
In order to improve the plastic deformation resistance of asphalt, additives such as the SBS, polyethylene (PE), and polyphosphoric acid (PPA) are used in asphalt industries [31]. However, the performance improvement is unilateral, and it is hard to improve both the asphalt high-and low-temperature performance simultaneously.A clean and sustainable deicing additive was prepared via the adsorption of acetate anions (Ac-) by magnesium (Mg) and aluminum (Al) calcined layered double hydroxide (Mg/Al-CLDH).

Repurposing waste plastics into cleaner asphalt pavement
Such an additive was added into reclaimed asphalt pavement (RAP) to improve its performance. They found that the asphalt samples containing RAP and PET derived additives provided better overall performance compared to the conventional binder. This is deemed to be an approach to deal with a relevant recycling problem while The overall objectives of this study were to determine the most appropriate additive for improving the physical properties and the medium- and high-temperature performances (mechanical performanceExperimental Study to Determine the Most Preferred Additive

Recent development, utilization, treatment and performance
An approach of adding Evotherm-DAT as additive into asphalt rubber (AR) binders can provided lower preparation temperature while maintaining the performance of the binder, therefore conserving energy. It performed better at low and intermediate temperatures but less effective at high temperatures (Yu et al., 2017). As a result, the End-of-life tires (ELT) are a worldwide problem. Rubber, steel, and different textile fibers are the by-products of ELT. Unlike rubber and steel, waste tire textile fibers (WTTF) are disposed of in landfills or burned. This study developed an additive made with WTTF to be incorporated into conventional hot mix asphalt (HMA), and its Polymers Free Full-Text Development of a New Additive

To reduce the deleterious effects of spreading chlorine salt on environment and asphalt pavement, a method of integrating chloride deicing additive (Cl − DIA) into asphalt mixtures has been developed (Goh et al., 2011, Jones, 1981, Ninomiya et al., 1993, Sheftick, 1991, Szatkowski and Swanson, 1986).Asphalt Binder . To obtain a granular additive, which facilitates the incorporation of the fiber into the asphalt mixes, a cationic asphalt emulsion was chosen as the binder. The cationic asphalt emulsion used was CRS-2, which conforms to Chilean specifications . It is a rapid setting cationic emulsion, with 65% asphalt binder (AB), and it Development of a New Additive Based on Textile Fibers of

Using Asphalt as an Additive for Waste Cross-Linked
With good insulation, cross-linked polyethylene (XLPE) cables are widely used as an important basic material for power transportation. Due to being insoluble and infused, the cross-linked network structure caused a challenge in the recycling of waste XLPE, which is usually treated by incineration and landfilling. In this research, XLPE was part-de-cross The use of waste products in the production of asphalt binders and asphalt mixtures has become widespread due to economic and environmental benefits. In particular, the use of recycled waste plastic in asphalt binders and mixtures is gaining more attention.
