 Anyone who works within a local community will already know that sometimes unpleasant smells from bitumen manufacturing plants, asphalt mixing areas and laying operations can lead to strong reactions from fellow workers and local residents who are quick to communicate with facility managers and regulatory agencies. 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 works on 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. After appropriate addition Shell Bitufresh will maintain a low odour profile of the bulk bitumen through the manufacture of the asphalt mixture and laying of the pavement. Once properly dosed the reduction of bitumen odour will persist for at least two weeks under normal storage conditions. |
