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

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: Review
Chemistry & Chemical Technology, 2016The main reasons and ways of bitumen modification by polymers were examined. Positive and negative aspects of the usage of different polymer modifiers (elastomers, thermoplastic elastomers, reactive polymers, thermoplastics) were analysed. The authors’ achievements concerning modification of bitumen by various polymers, namely indene-coumarone ...

Polymer-Modified Bitumen Using Ethylene Terpolymers
Petroleum Science and Technology, 2007Polymer modified bitumen (PMB) is used in various construction applications, especially in motorways. The aim of this study is to improve features of 60/70 penetration grade, modified bitumen used on highways. Increasing the sensitivity to temperature and oxidation resistance are very important points for the modified bitumen.

Polymer modified bitumen: Optimization and selection
Materials & Design (1980-2015), 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.

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.

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

Modified Bitumens Containing Thermoplastic Polymers
Rubber Chemistry and Technology, 1980Abstract The mechanical and viscoelastic behaviour of bitumen, both at high and low temperature, is noticeably improved by addition of thermoplastic polymers such as thermoplastic SBS rubbers and atactic polypropylene. These polymers can be used complementary to each other. Atactic polypropylene decreases the flow of bitumen at room temperature,
