To investigate the effect of recycled engine oil bottoms (REOB) as a compatibilizer on properties styrene–butadiene–styrene-modified bitumen (SBS-PMB), this paper studied preparation method, properties, and micro-mechanism composite modification matrix with SBS REOB. Firstly, multi-factor orthogonal experiment determined optimal scheme REOB/SBS composite-modified (REOB/SBS-PMB). Then, high-temp...

This paper is motivated by the limited research available evaluating comprehensive effects of natural rubber bitumen modification (NR) for pavement applications. A detailed laboratory programme was carried out to evaluate influence NR on high-intermediate-low temperature performance, including rheological characterisations and performance-related tests (fatigue cracking, thermal fracture perman...

Abstract The durability, fatigue resistance, and low-temperature behavior of asphalt layers are greatly affected by the properties bitumen. Therefore, composition bitumen is frequently modified to improve performance mixtures. Sty-rene-butadiene-styrene (SBS) has been most often used additive recently. Researchers trying cohesive adhesive binders such polymer-based additives. In this study, 160...

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...
