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.

Polymer Modified Bitumen

2001
The dynamic mechanical behaviour of bitumen (BIT)modifaed with styrene-butadiene-styrene bloc copolymer (SBS) were investigated. dynamic mechanical analysis (DMA) were performed in the temperature range -100 to 100 C. The primary viscoelastic function were determined at the traffic frecuency, 5 Hz.

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.

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).

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.

Determination of polymer content in modified bitumen

Materials and Structures, 2003
Polymer-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.

Bio-polymer as a bitumen modifier

2022
Bitumen 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 ...

Bitumen modified with reactive polymers

2012
The aim of this paper was to study the effect of the addition of two types of reactive terpolymers on the bitumen rheology. Eight polymer-modified bitumens (PMBs) were produced by mixing two types of bitumens with two types of reactive polymers, ethylene – butylacrylate – glycidylmethacrylate Elvaloy AM and Elvaloy 4170 terpolymers, using polymer ...
