Recycling of Waste Tyre Rubber into Sustainable Low-Noise Rubberized Asphalt Pavement
Date, time & venue
17th November 2021 (Wednesday), 17:00-18:00, Seminar via Zoom Meeting
HKIE Civil Division and The Hong Kong Polytechnic University
Asphalt rubber (AR), which is composed of raw asphalt binder and at least 15% of waste tyre rubber modifier, is often considered a sustainable paving material because of its various benefits, such as recycling waste tyres, enhancing pavement performance, and reducing tyre-road noise. However, AR also faces the concern of higher emission and energy consumption during construction, because its high viscosity requires high construction temperature. This webinar will start with the basics of different approaches/technologies to recycle waste tyres into asphalt pavement, followed by more than ten years’ research and development experience in Hong Kong in developing the durable low-noise rubberized asphalt pavement which also has low construction emission. In the end, some recent study on recycling waste plastics into asphalt pavement will be briefly introduced.
Free of Charge.
