Abstract

This study examines consumer habits by analyzing retail patterns across vari- ous demographics using a dataset encompassing 3,900 transactions. The data includes variables such as age, gender, item purchased, purchase amount, loca- tion, and more, allowing for a comprehensive analysis of consumer behavior. Key insights reveal significant trends in purchasing decisions influenced by de- mographic factors like age and gender, as well as external elements such as sea- sonality and promotional activities. The analysis identifies predominant shop- ping preferences among different age groups, highlighting the influence of dis- counts and promotional codes on purchasing behavior. Additionally, the study explores the correlation between customer loyalty, as indicated by subscription status and frequency of purchases, and spending patterns. By decoding these retail patterns, this research provides valuable insights for retailers aiming to optimize marketing strategies and enhance customer engagement through tar- geted interventions. The findings contribute to a deeper understanding of how demographic factors shape consumer behavior, offering actionable insights for businesses seeking to adapt to evolving market demands.

Abstract

In the modern era, pollution from plastic waste has become a growing concern, particularly due to the widespread use of plastics like plastic bottles. This research explores a novel approach for recycling plastic waste by incorporating plastic bottles into bitumen for the enhancement of Hot Mix Asphalt (HMA). Alongside this, nano-materials such as carbon nanotubes (CNTs), graphene, nanosilica, and nanoclays were used to further improve the mechanical, rheological, and durability properties of the modified bitumen. The plastic waste, in the form of plastic bottles, was added in varying proportions (3%, 5%, 8%, 10%, and 12% by weight of total mix) to investigate its effect on bitumen’s performance. The study conducted a series of tests, including Dynamic Shear Rheometer (DSR), Rotational Viscosity, Penetration Test, Softening Point Test, and Scanning Electron Microscopy (SEM), to evaluate the rheological and mechanical properties. The results revealed that the incorporation of plastic waste significantly improved the bitumen’s resistance to rutting, cracking, and fatigue, while nano-additives further enhanced high-temperature stability and elastic recovery. As the percentage of plastic waste in the bitumen increased, improvements in resistance to aging and moisture susceptibility were observed. Additionally, the plastic-modified bitumen exhibited better stability, improved resilience to temperature fluctuations, and enhanced mechanical strength. These findings suggest that combining plastic waste and nano-materials in bitumen can contribute to more sustainable road infrastructure, reducing plastic pollution while improving the performance and longevity of asphalt pavements.
