"Bitumen is changing," says Massimo Menestrina, CEO of Menestrina, which manufactures specialist bitumen processing plants. Menestrina is at the forefront of these changes. Its air-blowing and polymer modification technologies are being used to improve the performance of poor-quality bitumen, and it has invented a new process which promises to transform recycled tyre rubber into a binder which can be used instead of bitumen. Today, asphalt suppliers and road contractors need to better understand the chemical properties of bitumen, says Menestrina, the fourth generation of his family to work in the business. "The focus is moving away from asking the supply chain to provide you with the products you need to work with the feedstock you receive and adapting it in-house," he says. "You can't rely on someone upstream to do that anymore." |
