The colloidal structure of bitumen: Consequences on the rheology and on the mechanisms of bitumen modification

Advances in Colloid and Interface Science, 2009
The use of bitumen as a construction material dates back to antiquity. The materials in use then were mostly naturally occurring in contrast to modern bitumens which have become highly technical artificial materials. This article reviews the current understanding of bitumen structure and the consequences in terms of properties, with a strong emphasis ...

Effect of ageing process on bitumen and rejuvenated bitumen

Construction and Building Materials, 2017
Abstract In the last few decades, highway agencies and the paving companies have invested huge efforts on increasing the amount of reclaimed asphalt (RA) to be introduced in the production of new asphalt concrete (AC). This technique, so-called hot recycling of RA, offers several economical and environmental advantages tightly related to the ...

Treatment of bitumen burns

Annals of Emergency Medicine, 1982
To the Editor: Burns due to contact with hot pitch and tar are one of the five safety problems which account for 62% of all injury cases and 76% of all Worker's Compensation costs of the roofing and sheet metal industry. 1 Sixteen percent of all accidents involving roofers and sheet metal workers are due to burns from hot materials, and 17% of those ...

Properties of Polymer Modified Bitumen after Rubber-Bitumen Interaction

Journal of Materials in Civil Engineering, 2002
This paper describes results from a laboratory investigation into the effects of the interaction between a styrene-butadiene-styrene (SBS) modified bitumen and recycled crumb rubber on the mechanical performance of impact absorbing asphalt (IAA), an asphaltic material that has applications as a sports and safety surface.
