Polymer modified bitumen: Optimization and selection
Materials & Design, 2014Polymer modification of bitumen has been commonly performed since the 1980s in order to decrease bitumen (and pavement) susceptibility to high and low temperatures, allowing reduction in common failure mechanisms as rutting and cracking. Bitumen modification has been commonly performed by addition of thermoplastic or elastomeric polymers.

Production of recycled plastic modified bitumen- Effect of base bitumen [PDF]
In this study, two different viscosity grade base bitumen (VG10 and VG30) and 3 dosages (2%, 3%, and 4%) of recycled low-density polyethylene (RLDPE) were selected for the preparation of the recycled plastic modified bitumen (RPMB). All modified bitumen were evaluated for physical, morphological, and rheological properties.

Properties of Natural Bitumen Gilsonite Modified Bitumen
ICTE 2015, 2015This article introduces the characteristics of the gilsonite and the natural bitumen gilsonite. It also discusses the performances, effect, modified mechanism and using of the natural bitumen gilsonite modified bitumen. A series of tests of the natural bitumen gilsonite modified bitumen were made. These included asphalt technical property, rutting test

Standard methods of characterization of bitumen, BIT, and of polymer modified bitumen, PmBs, do not provide sufficient information. We propose to rely on determination of rheological properties which are much more informative. Along theses lines, we have determined rheology before and after the Rolling Thin Film Oven Test, RTFOT.

Properties of Polymer Modified Bitumen after Rubber-Bitumen Interaction
Journal of Materials in Civil Engineering, 2002This paper describes results from a laboratory investigation into the effects of the interaction between a styrene-butadiene-styrene (SBS) modified bitumen and recycled crumb rubber on the mechanical performance of impact absorbing asphalt (IAA), an asphaltic material that has applications as a sports and safety surface.

Modified sulfur bitumen binders for bitumen-mineral compositions
AIP Conference Proceedings, 2019The properties of modified sulfur bitumen binders based on viscous petroleum bitumen, industrial sulfur and polymeric petroleum resin were studied. In selecting the compositions of the modified sulfur bitumen binders, the experiment planning method was used.

Polymer‐modified bitumen of recycled LDPE and maleated bitumen
Journal of Applied Polymer Science, 2012AbstractMaleated bitumen was prepared by the reaction of penetration grade bitumen (80/100) with maleic anhydride at 150°C for 2 h under nitrogen atmosphere. The effectiveness of maleation was assessed in bitumen–recycled low‐density polyethylene (LDPE) blends in terms of their softening point and elastic recovery.

Characterization of bakelite-modified bitumen
Innovative Infrastructure Solutions, 2017This study investigated the influence of Bakelite on the physical, performance, and mechanical properties of bitumen binder. Bakelite is the trade name of phenol formaldehyde—a thermosetting type of plastic. It is a polymer amorphous in nature having three-dimensional structure. This imparts hardness, strength, and rigidity. Bakelite was blended in the
