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 ...

Properties of Natural Bitumen Gilsonite Modified Bitumen
ICTE 2015, 2015This article introduces the characteristics of the gilsonite and the natural bitumen gilsonite. It also discusses the performances, effect, modified mechanism and using of the natural bitumen gilsonite modified bitumen. A series of tests of the natural bitumen gilsonite modified bitumen were made. These included asphalt technical property, rutting test

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 ...

Effect of ageing process on bitumen and rejuvenated bitumen
Construction and Building Materials, 2017Abstract 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 ...

Properties of Polymer Modified Bitumen after Rubber-Bitumen Interaction
Journal of Materials in Civil Engineering, 2002This 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.

Hydrotreatment process kinetics for bitumen and bitumen-derived liquids
Fuel, 1994Abstract Hydrodenitrogenation, hydrodesulfurization and resid conversion data for the Whiterocks bitumen and bitumen-derived liquid were analysed using a modified power rate law model. The data were obtained with a fixed-bed reactor in the upflow mode.

A Model For The Viscosity Of Bitumen/Bitumen Fractions - Diluent Blends
Journal of Canadian Petroleum Technology, 1992Abstract A procedure is presented for predicting the mixture viscosity of bitumen or bitumen fractions ("cuts") blended with liquid diluents, such ar toluene. The following simple (additive) viscosity mixing rule is evaluated for binary and multicomponent mixtures of bitumen fractions and toluene (as the diluent):
