Environmental Science and Pollution Research
Conventional bitumen is a viscoelastic material composed of asphaltene and maltene. It is prepared by air-blowing, but this approach makes the bitumen more brittle and susceptible to temperatures. To decrease the temperature susceptibility, synthetic polymers or additives are used to make polymer-modified bitumens.

Ageing Performances of Asphaltite Modified Bitumens; Comparisons with Equivalent Petroleum Bitumens
2015This work focuses on the ageing behavior of asphaltite modified paving bitumens. The addition of asphaltites in soft petroleum bitumens gives harder binders which are suitable for the production of high modulus bituminous mixes used in pavements construction. Such techniques are already used in several projects.

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.

Bitumen modified with reactive polymers
2012The 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 ...

Bio-polymer as a bitumen modifier
2022Bitumen 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 ...

Adhesion properties of modified bitumen
2022The article presents the results of determining the adhesion properties of bitumen modified with polymeric additives based on polypropylene and polystyrene foam with graphite additives. It has been found that a sample with the addition of 3% (mass.) Polypropylene (peel strength of the plate 2.47 N/cm²; peel of the coating from the marble plate at a ...
