“…The addition of Elvaloy to B2 does not cause changes at low temperatures after aging. If we compare the results of our previous research into bitumen modified with nonreactive polymers, it is evident that the modification with Elvaloy shows no large increase in the values of G* and g* after aging [6,29]. From our previous research, in the case of bitumen modified with nonreactive polymer after aging, the d values of PMBs on the d/T curve are evidently lower, and the elastic plateaus (indicator of formed polymer network) are affected.…”

This article presents experimental results related to rheological viscoelastic properties of polymer modified bitumens, PmBs. Experiments were performed by a dynamical shear rheometer before and after thermo‐oxidative aging. Two types of bitumens with different asphaltene contents were modified by the addition of two types of reactive ethylene terpolymers, Elvaloy AM, and Elvaloy 4170, with a different percentage of reactive functional group, glycidylmethacrylate, GMA. Results of the investigation indicate that the degree of reactive polymer modification is a function of bitumen type, bitumen‐polymer compatibility, and polymer concentration. Polymer modification improves the following physical properties of the base bitumen: penetration, softening point, temperature susceptibility, and elastic recovery. Reactive polymers are effective binder modifiers that improve the susceptibility to high temperature of asphalt mixes, and also their rutting resistance, contribute to their good storage stability and make them less sensitive to aging. This is a result of the formation of a chemical bond between the polymer and molecules of asphaltenes. POLYM. ENG. SCI., 54:1056–1065, 2014. © 2013 Society of Plastics Engineers

In this work, asphalt modifiers consisting of a series of poly(glycidyl methacrylate‐ran‐styrene)‐block‐poly(butyl acrylate)‐block‐poly(glycidyl methacrylate‐ran‐styrene) tri‐block copolymers (GS‐BA‐GS) were synthesized via reversible addition‐fragmentation chain transfer polymerization. Particular attention is given to the influence of controlled copolymer structures on the physical properties, morphology, thermal stability, and rheological behavior of the asphalt blends. Results show that the degree of asphalt modification is a function of the copolymer structure in relation to the epoxide content in the chain ends of the copolymers. The rheological, thermal, and microstructure analyses reveal that the addition of reactive copolymers increases chemical interactions with the polar fraction of asphalt. Absence of gelation in addition to improvements in viscosity, elasticity, storage stability are observed in the blends with GMA concentrations of 2%–4% with respect to copolymers without functional groups. © 2018 Wiley Periodicals, Inc.

RECLAIMED Asphalt Pavement (RAP) is beneficial because it provides and decreases the cost of the construction, while increasing environmental sustainability. The main purpose of this study is to investigate the best practice of RAP in Egypt, in order to determine the effect of using 100% RAP instead of using virgin aggregates and asphalt. The study also investigates the effect of thermoplastic elastomers polymer as asphalt modifier. Also, improve the mechanical and physical characteristics and hence improving the quality of asphalt paving, increase asphalt-paving age and reduce the cost.Nano acrylate copolymer has been prepared with different wt.% and was tested for Fourier Transforms Infrared (FTIR), Molecular Weight (Mwt), Thermo Gravimetric Analysis (TGA) and Transmission Electron Microscopy (TEM). A 4wt.% of the prepared nanoemulsion copolymer was mixed with virgin asphalt as a polymer modifier, to improve and reuse of the RAP. The modified binder was tested. The tests conducted include penetration, kinematic viscosity, softening point and specific gravity. Application of Marshall mix design types; Hot Mix Asphalt (HMA), Warm Mix Asphalt (WMA) and Cold in place Recycled (CIR). Four different mix designs were used; control mix contains virgin asphalt by HMA, where the other three mix designs were Polymer Modified Asphalt (PMA) by HMA, WMA and CIR. The research results showed that, using 4 wt.% of the prepared nanoemulsion copolymer producing HMA and WMA with higher stability compared to the control mix and CIR. Keywords
