Polymer Modified Bitumen: Review

open access: yesChemistry & Chemical Technology, 2016
The main reasons and ways of bitumen modification by polymers were examined. Positive and negative aspects of the usage of different polymer modifiers (elastomers, thermoplastic elastomers, reactive polymers, thermoplastics) were analysed. The authors’ achievements concerning modification of bitumen by various polymers, namely indene-coumarone ...

Effect of ageing on the morphology and creep and recovery of polymer-modified bitumens [PDF]

open access: yes, 2018
Polymer additives are used to improve the properties of road bitumens including their oxidative resistance. However, their usage as anti-oxidative materials remains relatively unclear.

Characterizing the properties of sustainable semi-flexible pavement produced with polymer modified bitumen

open access: yesPeriodicals of Engineering and Natural Sciences (PEN), 2021
Semi-Flexible Pavement (SFP) is a composite type of pavement produced by manufacturing of porous asphalt mixes using open graded aggregate gradation to create 20-35% of voids filled with grout (cement paste, cement mortar, etc.….). The resulting pavement

PERFORMANCE OF ASPHALT MIXTURES WITH A NEW TYPE OF RUBBER MODIFIED BITUMEN

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering, 2021
The rubber modified bitumen 45/80-55 (RMB 45/80-55) product has been used in Hungary as bituminous binder for asphalt mix production since 2013. It is a new kind of rubber bitumen manufactured using patented technology. Over the past 8 years, it has been

Polymeric Additives Effect on Mechanical Properties for Bitumen Based Composites [PDF]

open access: yesEngineering and Technology Journal, 2011
Bitumen binder is a thermoplastic liquid and the elementary analysis of the bitumen manufactured from a variety of crude oils shows that most bitumen contains carbon, hydrogen, sulphur, oxygen, and nitrogen. At high temperature or low loading, it behaves

Research of the petroleum road bitumen modification process with secondary polyethylene terephthalate [PDF]

open access: yesE3S Web of Conferences, 2023
Modification of bitumen with polymers is an effective way to improve its properties. Despite the sufficiently widespread use of this method, currently there are practically no appropriate methods of this process calculation. Moreover, there are almost no

Texture analysis of polymer modified bitumen images [PDF]

open access: yesInternational Journal of Materials Research, 2011
Abstract This study aims to analyze the textural features extracted from microscopic images of elastomeric and plastomeric type polymer modified bitumen (PMB) including five different types and contents of polymers. Fluorescence microscopy was used to capture microscopic images from thin films of PMB samples at different magnification scales (400×, 100×

Analysis of the Effects of Ageing on the Cohesive Strength of Polymer-Modified Bitumen at Low Temperatures

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2018
The decay law on the ageing process of the cohesive strength of styrene-butadiene-styrene(SBS)- and polyethylene(PE)-modified bitumens at low temperatures was investigated. The rotated-thin-film oven test was used to age the two types of polymer-modified
