Webinar on Upcycling of Sewage Sludge Ash into Foaming Warm Mix Asphalt Additive for Sustainable Asphalt Pavement Construction

Technical Seminar:
Upcycling of Sewage Sludge Ash into Foaming Warm Mix Asphalt Additive for Sustainable Asphalt Pavement Construction

Date, time & venue

7 December 2022 (Wednesday), 17:00-18:00, Seminar via Zoom Meeting

 

Organized by

HKIE Civil Division and The Hong Kong Polytechnic University

Programme Highlight

Waste recycling/upcycling has become an important topic in highway and pavement engineering, because of its significant economic and environmental benefits. This presentation will start with a brief introduction to the green technologies developed in Hong Kong to recycle various types of wastes, such as reclaimed asphalt pavement, waste tyre rubber, and waste plastics, into pavement. Then, a recent study on converting sewage sludge ash into zeolite-based foaming warm mix asphalt additive, which can reduce the construction temperature of asphalt pavement by at least 20 oC without compromising its mechanical performance, will be presented. In the end, some remarks and discussions on recycling wastes into pavement will be provided.
