<br/><br/> The rapid increase in Tetra Pak waste has posed significant environmental challenges, including rising water pollution and unsustainable resource consumption. To address<br/>these issues, this study explores the potential of recycling Tetra Pak, a non-biodegradable<br/>packaging material, into asphalt roof shingles as an innovative, sustainable, and durable<br/>roofing solution. The research investigates the mechanical properties of the shingles, focusing on their impact resistance and flexural strength. Five mix design ratios were<br/>developed (40:45:10:5, 45:40:10:5, 50:35:10:5, 55:30:10:5, and 60:25:10:5) using Tetra<br/>Pak, asphalt, limestone, and silica sand, with three replicates for each mix. Mechanical<br/>tests, including Impact Resistance (ASTM D5420-21) and Flexural Strength (ASTM<br/>C120), were conducted to assess durability. Results revealed that Mix 3 (50% Tetra Pak, 35% asphalt, 10% limestone, and 5% sand) demonstrated the highest impact resistance, tolerating a drop height of 120 cm, while Mix 5 showed superior flexural strength of 0.33<br/>MPa. Additionally, a panel of 30 experts, including architects, civil engineers, and<br/>professors, evaluated the shingles' acceptability based on six criteria: Aesthetic, Workability, Durability, Economy, Safety, and Marketability. Using the TUP Evaluation<br/>Form, the shingles achieved an overall "Very Acceptable" rating, with an average score<br/><br/>of 4.84. This study highlights the viability of Tetra Pak-based asphalt shingles as an eco-<br/>friendly alternative roofing material. While results are promising, further research is<br/><br/>recommended to enhance the product’s long-term durability and weather resistance. By<br/>integrating recycled materials, this innovation contributes to
