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.

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.

Dynamic mechanical behavior of polymer modified bitumen
Materials Research Innovations, 2002The dynamic mechanical behaviour of bitumen (BIT) modified with styrene/butadiene/styrene block copolymer (SBS)were investigated. Dynamic mechanical analysis (DMA) were performed in the temperature range -80 to 60 oC. The primary viscoelastic functions were determined at the traffic frequency, 5 Hz.

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.

Determination of polymer content in modified bitumen
Materials and Structures, 2003Polymer-modified bitumen (PMB) has been increasingly used to enhance pavement performance. Two styrenebutadiene-styrene (SBS) copolymers were mixed with two bitumens by weight of the blend. This paper aims at developing the procedure to determine the proper polymer content to be mixed with bitumen.

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.

Effect of polymer modifiers on the properties of bitumen
Journal of Elastomers & Plastics, 2013This article presents an investigation about the polymer-modified bitumens (PMBs) containing styrene–butadiene–styrene (SBS) block copolymers with different structures, linear (SBS-L) and radial (SBS-R), semicrystalline copolymer ethylene–vinyl acetate (EVA), and terpolymer ethylene–butyl acrylate–glycidyl methacrylate, Elvaloy AM and Elvaloy 4170.

Stress Relaxation in Polymer-Modified Bitumens
Colloid Journal, 2002The efficiency of BNK-40/180 bitumen modification with a blended thermoelastoplast and its components is studied by measuring the kinetics of the stress relaxation in melts. Asphaltene agglomerates are disclosed to be the main kinetic units of the stress relaxation in bitumens and bitumen–polymer compositions.

Bio-polymer as a bitumen modifier
2022Bitumen modifiers are used in order to improve or restore bitumen physical and mechanical performance. Traditionally bitumen modifiers are products of crude oil, such as: soft bitumen and styrene-butadiene-styrene (SBS). As crude oil production declines and the environmental and financial costs of crude oil extraction increase, there is a need to ...
