Experimental Validation of the Dual-Oxidation Routes in Bituminous Binders

Oxidative ageing in bituminous materials is considered to be one of the most important factors for distress types in road applications. The increasing interest in oxidative ageing has highlighted the need for a thorough understanding of the oxidation mechanisms at molecular level. This paper offers some insight in the validity of the proposed...

Investigating the High- And Low-Temperature Performance of Warm Crumb Rubber-Modified Bituminous Binders Using Rheological Tests

Rubberized asphaltic materials have been frequently combined with warm-mix asphalt technologies to tackle the issues of high energy consumptions and emissions during construction. Effective and accurate characterization of binder properties is conducive to the improvement of long-term pavement performance. The current study aims to quantify...

Characterization of bitumen modified with pyrolytic carbon black from scrap tires

Pyrolytic carbon black (CB _p ) from scrap tire pyrolysis is a potential modifier for the bitumen industry. Binders containing different contents of CB _p were prepared and experimentally investigated to examine the effects of CB _p on the electrical and thermal conductivity, conventional physical properties,...

Experimental investigation of the oxidative ageing mechanisms in bitumen

Oxidative ageing in bituminous materials is considered one of the most important factors for distress types in road applications. This paper aims to offer insights into the validity of commonly held beliefs regarding the oxidation phases of ageing in bitumen, the fast- and the slow-rate phase, and explore the main oxidation products formed...
