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.

Styrene-Butadiene-Styrene polymer modified bitumen: A review on compatibility and physico-chemical properties

Physica Scripta
The triblock elastomeric copolymer Styrene-Butadiene-Styrene (SBS) improves the engineering properties of bitumen and the performance parameters of flexible pavements. Although research investigations have been conducted worldwide, the literature lacks a

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.

Direct Insertion Analysis of Polymer-Modified Bitumen by Atmospheric Pressure Chemical Ionization Ultrahigh-Resolution Mass Spectrometry

, 2021
Bitumen is a highly complex matrix, generally obtained as vacuum residues of the crude oil distillation. This material is majorly used as binder for the construction of asphalt pavement.

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.

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.

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 ...
