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.

Thermal fatigue of polymer modified bitumen
Journal of Thermoplastic Composite Materials, 2011 Thermal fatigue is a serious distress in flexible pavement that reduces performance and durability. Many researchers have made efforts to understand the thermal fatigue phenomenology. Until now, there has not existed a standard test method for evaluating mixture and binder resistance to thermal fatigue.

, 2011 Road bitumen undergoes, during its service life, an ageing process that leads to a material's hardening. But, when a polymer modified bitumen (PmB) has been used, what happens after oxidation/ageing is very complex to analyse, due to the number of chemical parameters involved: the nature of the polymer (structure and chemistry), the chemistry of ...

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.

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.
