Environment
Bitumen is a non-ecologically toxic product which presents no danger to plant and aquatic environments.
Due to its longevity, bitumen can be recycled, as is common practice with asphalt roads and paving. The use of "old" road material (RAP) as a component in making fresh asphalt is relatively common practice. The asphalt specifications indicate the amount allowed and the methods to calculate the contribution of the old (hardened) bitumen to the new mixture.
Roads can be recycled by two main processes:
In-situ - where the broken-up "old" road material is re-formed into (a part of) the new structure.
Off-site where the RAP is taken to a plant to be used as a component of a new mixture.
The process is environmentally friendly because it saves on waste disposal, and also saves on the use of new resources (aggregate and bitumen).
The RBA, through its Health, Safety and Environmental Committee, reviews and develops operational activities and procedures which are environmentally sympathetic. The RBA also works closely with the Environment Agency in the drafting of Process Guidance Notes which establish fume emission levels and controls for bitumen.
Material Safety Data Sheets, available from bitumen suppliers, provide environmental information pertaining to specific products.
The RBA and its member companies can offer advice and on-site guidance in assessing the environmental impact of bitumen processes and procedures.
