Bitumen: Solutions for Tough Conditions


Bitumen is produced by the partial distillation of crude petroleum oil, also known as mineral tar and is present in asphalt. It constitutes of 87% carbon, 11% hydrogen and 2% oxygen. Bitumen is a combination of hydro carbons and thermoplastic material having strong tarry odor while stiffness is dependent on temperature. The temperature-vs.-stiffness relationship of bitumen is pivot on the source of crude oil and the method of refining and available in bulk and packed in drums. Crumb Rubber Modified Bitumen (CRMB) is like bitumen with alteration in physical properties like addition of crumb rubber making it more resistant to temperature variations, weather and high traffic loads, reduced maintenance costs and excellent driving comfort. – PowerPoint PPT presentation
