In an exciting development for sustainable infrastructure, researchers at the Advanced Pavement Laboratory within Arizona State University’s School of Sustainable Engineering and the Built Environment have created a revolutionary solution to asphalt pavement temperature susceptibility challenges. By incorporating aerogel composites into asphalt mixtures, they aim to enhance thermal insulation and increase the durability of roadways.

The Power of Aerogel

Aerogel, known for its exceptional insulating properties, is encapsulated with co-products from the petroleum-refinery system and blended into asphalt. This innovative blend, referred to as aerogel-modified bituminous materials, has demonstrated significant potential in reducing temperature susceptibility in asphalt. The improved thermal resistance not only enhances pavement durability but also contributes to energy efficiency, ultimately reducing carbon dioxide emissions.

Pioneering Research and Development

The development and ongoing research of this aerogel composite are being advanced through the National Center for Infrastructure Transformation (NCIT), led by Prairie View A&M University (PVAMU). This collaborative effort underscores the importance of interdisciplinary research and the practical application of innovative materials in infrastructure projects.

Recognized Excellence

The groundbreaking work by the NCIT ASU research group has garnered international recognition. Recently, the team was awarded one of the twelve 2023 Global Road Achievement Awards in the Research Category by the International Road Federation (IRF). The IRF Awards Programs celebrate outstanding individuals and projects that drive the industry forward in social and economic development.

The prestigious award was announced at two significant events: the sixth Annual IRF Global R2T Conference and Exhibition, and the Arizona Pavements/Materials Conference, both held on November 16, 2023. These platforms highlighted the impact and potential of the aerogel composite in transforming the future of road construction and maintenance.

Future Prospects

The continued research and implementation of aerogel-modified bituminous materials promise a more sustainable and resilient infrastructure. As the NCIT and ASU researchers push the boundaries of materials science, their innovations pave the way for safer, more durable roadways that contribute to environmental sustainability.
