Bitumen is a commonly used material for road construction. According to environmental regulations, vegetable-based materials are applied for binder modification. Fluxed road bitumen containing a bio-flux oxidation product increases the consistency over time. The efficiency of crosslinking depends on the number of double bonds and their position in the aliphatic chain of fatty acid. The main goa...

This study is carried out to explore the effect of nano materials (SiO2 & TiO2) on the physical and rheological properties of Bitumen. To achieve this goal, Nano materials are blended in bitumen in various percentages (0.3, 0.6, 0.9 and 1.2%). The physical and rheological properties of modified binders are characterized using a penetration, softening point, kinematic viscosity and a dynamic...

This research aims to define an efficient and fast quantification of bitumen removal on the road surface by Digital Imaging Processing (DIP) and spectral analysis. The retrieval of bitumen removal is an important issue for road management and environmental studies related to asphalt wear and environmental pollution. The calculation of the Exposed Aggregate Index (EAI), based on DIP, allows to q...

The population of our country is increasing rapidly and due to it plastic waste is also increasing day to day due to urbanization, development activities and changes in life style, which leading extensive environment pollution. Thus disposal of waste plastic is a threat and become a serious problem globally due to their nonbiodegradability and anaesthetic view. Since these are not disposed scie...

High modulus bitumens modified by polystyrene-block-polybutadiene-block-polystyrene (SBS) with different molecular structure were investigated on dynamic shear rheometer and fluorescence microscopy to evaluate viscoelastic properties and morphology of binders. The results shows that storage modulus (G’) is obviously less than loss modulus (G”), which means viscous behaviour of bitumen is domina...

with respect to the physical and mechanical limited qualities of bitumen, it benefits from certain specificability in application and its life service. polymers as the most important modifiers of bitumen are applied to it in order to improve its functional efficiency. among various polymers, styrene-butadiene- styrene (sbs) is the best modifier of the bitumen. in this work, sbs polymer as one o...

Nowadays, utilisation of Nano-materials as one of the most recent methods of bitumen modification has attracted attention of many researchers. However, not enough research has been pursued on their mixing with bitumen, because of their dimensions and specific properties. In this study, the carbon Nano-tubes were mixed with bitumen using different mixers and some images were recorded employing a...

A huge number of laboratory testing techniques is known for assessing adhesion properties between bituminous materials and aggregates in laboratory. Besides simple empirical tests (usually established for binder specification and quality assurance), like Rolling Bottle Test or static immersion test, elaborate test methods are in use like contact angle measurement of either bitumen droplets on m...

© Appl. Rheol. 20 (2010) 63293 DOI: 10.3933/ApplRheol-20-63293 Abstract: Bitumen is undoubtedly the most important material in the construction and rehabilitation of flexible road pavements. By increasing the temperature, bitumen changes from brittle solid, to viscoelastic solid and finally to Newtonian fluid. The rheological characteristics of bitumen also vary greatly due to aging, which is a...

Mummification was practised in ancient Egypt for more than 3000 years, emerging from initial observations of buried bodies preserved by natural desiccation. The use of organic balms (and other funerary practices) was a later introduction necessitated by more humid burial environments, especially tombs. The dark colour of many mummies led to the assumption that petroleum bitumen (or natural asph...
