Laboratory investigation of reclaimed asphalt material using cement and chemical additives

Monday, June 17, 2024

Room: Galleria
Abstract:

This research paper focuses on addressing the environmental impact of the cement industry and road building waste. It explores the use of chemical stabilizers alongside recycled asphalt and cement components in the base layer. The study examines various aspects, including strength, moisture compaction interaction, and microstructural characteristics. The results indicate that incorporating silica-based chemical stabilizers has positively influenced the mechanical properties of the mixture. The addition of these stabilizers led to an enhancement in the intensity of the C-S-H (Calcium Silicate Hydrate) gel, as revealed by microstructural analysis, which is responsible for the improved strength of the mixture. Moreover, the design displayed durability, with minimal ettringite formation in later stages. Overall, the application of this stabilizer offers a robust, eco-friendly, and long-lasting base layer solution.

Keywords: - Chemical stabilizers, Microstructure analysis, mechanical properties, Cement stabilized base.
