“…However, the average density of the aggregate with plastic content is still within the acceptable range. Overall, the results suggest that the addition of plastic waste to construction demolition waste aggregates can potentially enhance their mechanical properties, making them suitable for various construction applications (3,4) . The table shows the results of various tests conducted on conventional bitumen mix, including Marshall value and flow value.…”

Objectives:To develop an optimum bituminous mix by studying the properties of construction demolition waste aggregate (CDWA) and plastic waste as a partial replacement of natural coarse aggregate and bitumen. The performance and strength of the conventional bituminous mix and modified bituminous mix were studied using marshall stability test. Methods: Construction demolition waste aggregate (CDWA) is produced by crushing and screening old concrete from construction demolition waste, which is then used as a replacement for natural aggregates in pavement construction. This method helps reduce the need for new aggregate materials and conserves natural resources. The plastic waste is melted and blended with asphalt to create a more durable and weather-resistant material. This method reduces the amount of plastic waste in landfills and provides a sustainable solution for pavement construction. Findings: Based on the research, the optimum mix proportion of bituminous mix is found as 10% plastic waste blended with 15% construction demolition waste aggregate. The results of marshall stability test have shown significant increase in strength of pavement mixes by adding construction demolition waste and plastic waste. Novelty: The novelty of this study lies in its approach to addressing two major environmental issues simultaneously: waste management and sustainable construction practices. The study proposes a solution to reduce the amount of natural resources such as natural coarse aggregate and bitumen by blending alternate recyclable waste materials such as construction demolition waste aggregate and plastic waste shredded from waste bottles.

Cold mix asphalt is an energy-efficient and eco-friendly pavement material, yet its early strength is deficient. This study investigated the strength augment of cold mix asphalt through modification with geopolymer additives. Macro-strength was assessed via Marshall stability testing under varied geopolymer contents, curing durations, and water immersion conditions. Microscale analysis encompassed fluorescence microscopy to discern geopolymer-asphalt interactions and discrete element modeling to simulate the compression process. Results showed that stability rose and then fell as geopolymer content increased, with an optimal ratio of 4:3 between base asphalt and additive. Stability increased rapidly in the first 3 days of curing and accumulated at a slower rate afterwards. Fluorescence microscopy revealed that geopolymer bonded the asphalt to the aggregate surfaces. Modeling exhibited geopolymer resisted vertical loads and confined the aggregate. In summation, geopolymerization enhances cold mix strength by improving adhesion and generating a rigid 3D network encompassing aggregate particles. The discoveries provide guidance on formulating durable cold mix asphalt utilizing geopolymer additives.
