Polymer modified bitumen

Materials Research Innovations, 2012
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.

Polymer modified bitumen: Optimization and selection

Materials & Design, 2014
Polymer 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, 2002
This 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, 2012
AbstractMaleated 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.

Dynamic mechanical behavior of polymer modified bitumen

Materials Research Innovations, 2002
The 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.

Effect of polymer modifiers on the properties of bitumen

Journal of Elastomers & Plastics, 2013
This 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.

Artificial aging of polymer modified bitumens

Journal of Applied Polymer Science, 2000
This paper presents an investigation of artificial aging of polymer modified binders, prepared from three base bitumens and six polymers. Aging of the binders was performed using the Thin Film Oven Test (TFOT), the Rolling Thin Film Oven Test (RTFOT), and modified RTFOT (MRTFOT).

Stress Relaxation in Polymer-Modified Bitumens

Colloid Journal, 2002
The 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.
