Tipco Asphalt Group Hosts Webinar on “Sustainable Asphalt Binder” in Collaboration with KMITL to Advance Sustainable Asphalt Innovation
On April 29, 2026, at the Board Meeting Room of Tipco Asphalt, Khun Surapon Katekaew, Technical Department Director, as a representative of the company, together with the Faculty of Engineering, King Mongkut’s Institute of Technology Ladkrabang (KMITL), led by Associate Professor Dr. Preeda Chaturabong from the Department of Civil Engineering, jointly organized a webinar titled “Sustainable Asphalt Binder: From Scientific Innovation to Pavement Implementation.” The event was held under the Memorandum of Understanding (MoU) framework to promote collaboration and knowledge exchange in developing innovations in sustainable asphalt materials.
The webinar was divided into 3 key sessions, covering academic perspectives, research developments, and industrial applications in sustainable asphalt materials.
Part 1: Principles of Reclaimed Asphalt Pavement (RAP)
Associate Professor Dr. Preeda Chaturabong explained the concept and principles of Reclaimed Asphalt Pavement (RAP), which involves reusing old asphalt materials. This is done by improving their quality with a rejuvenator, a substance used to restore the properties of aged asphalt, bringing its performance closer to that of new material. This approach helps extend the pavement’s service life and reduces the need for new resources.
Part 2: Research on Bio Rejuvenators from Bio-based Materials
Researchers from KMITL, including Khun Multazam Hutabarat and Khun Suwapit Chamwon, presented their research on the development of bio-solvents from agricultural waste materials, such as pyrolyzed sugarcane bagasse and extracts from rice husks. These materials were developed for use as bio-rejuvenators to replace petroleum-based substances. The study found that their performance was comparable to that of conventional rejuvenators. However, the amount used must be carefully controlled to achieve the best quality and performance.
Part 3: Perspectives from the Industry
Khun Chaiyavid Wonghirunyawat, Product Development Manager at Tipco Asphalt Group, presented practical approaches for industrial applications. His presentation covered the ASTM D4552M-20 standard for rejuvenators, as well as mix design considerations for RAP in real use. He also shared progress on the testing of bio rejuvenators conducted in the company’s laboratory.
This webinar reflects the strong collaboration between the academic and industrial sectors in promoting knowledge sharing and exchange, developing innovations for practical applications, and supporting research, while paving the way for the future commercialization of natural-based products.
