 With this in mind Shell Bitumen has been working on ways to help our customers improve the ambient air quality around asphalt operations. The innovative formulation of Shell Bitufresh neutralises the substances that cause odour to be released from the bitumen. This effective mechanism is fundamentally different from other bitumen additives, which work by masking the smell. Shell Bitufresh has proven to be effective in both laboratory and field trials and a patent application for this technology has been filed. >> Shell Bitufresh
