Oxidized bitumen 90/15
Bitumen is a mixture of organic compounds composed of linear aliphatic, cycloaliphatic and aromatic derivatives. Linear aliphatic compounds are saturated linear carbon compounds. Cycloaliphatic compounds are ring structures that are composed of saturated carbon atoms, or cyclic structures that have a low number of unsaturated groups and aromatic compounds are those compounds that have at least one aromatic ring. The wide range of compounds and the varying nature of these compounds from oxidized bitumen 90/15 to bitumen make their individual isolation and identification a challenging proposition. The constituents of bitumen are usually separated into classes based on parameters such as solubility, polarity or hydrodynamic size.
Sampling of bitumen 90/15
Sampling of hot bitumen 90-15 is particularly hazardous because of the risk of heat burns from spills and splashes of the material. It is therefore essential that appropriate protective clothing is worn. The area should be well lit, and safe access to and egress from the sample point should be provided. Gantry access should be provided where samples are required from the tanks of vehicles, as climbing on top of vehicles should be avoided.
Life cycle assessment of bitumen 90-15
Life cycle assessment (LCA) is a tool to investigate the environmental aspects and potential impact of a Bitumen 90/15, process or activity by identifying and quantifying energy and material flows. LCA covers the entire life cycle, including extraction of the raw material, manufacturing, transport and distribution, product use, service and maintenance, and disposal (recycling, incineration or landfill). It is a complete cradle-to-grave analysis focusing on the environmental input (based on ecological effects) and resource use.
