Enhancing Asphalt Mixture Properties Through Waste Plastic And Steel Fiber Additives: A Comprehensive Study
Authors : Patil Dipali . Hedaoo Namdeo .
Abstract
Asphalt concrete is extensively used in road construction due to its superior mechanical properties and long-term durability. This study investigates the effect of steel fiber reinforcement on the performance characteristics of Stone Matrix Asphalt (SMA) and Asphalt Concrete (AC) mixtures. The Marshall mix design method was employed to develop SMA mixtures, and the Marshall Stability Test was conducted to determine the optimal steel fiber dosage. Steel fibers were incorporated to improve resistance to rutting and cracking, with the optimal dosage identified as 0.3% of the total mix weight. Furthermore, this study examines the behavior of steel fibers in SMA applications and optimizes the plastic content in AC mixtures. The results indicate that incorporating 2.5% waste plastic enhances AC's workability and handling characteristics compared to conventional mixtures. Additionally, a 3% waste plastic content demonstrated improved drain-down resistance and tensile strength properties, highlighting its potential for performance enhancement in asphalt pavements.
