An Evaluation of Mechanical Behaviors of Baghouse Dust in Asphalt Concrete Mix Using Discrete Element Method (DEM)

Abstract

The purpose of this study is to research the mechanical behavior of baghouse dust when integrated into asphalt concrete mixes, utilizing the Discrete Element Method. Baghouse dust, a byproduct of asphalt creation, presents natural removal challenges; nonetheless, its true capacity reuse in asphalt concrete could give an economical arrangement. This study plans to assess the attainability and execution ramifications of utilizing differing extents of baghouse dust in asphalt mixtures and combinations. The study starts by portraying the physical and synthetic properties of baghouse dust. Accordingly, substantial examples are ready with various rates of baghouse dust to break down what the consideration of this result means for the mechanical properties of the mix. The research uncovered that integrating baghouse dust into asphalt concrete by and large decreases the peak stress and strength attributes of the mix. In particular, the stress-strain curves show a lessening in top pressure values as the baghouse dust content increases. For example, the pinnacle pressure for the control mixes (0% residue) is roughly 25 MPa, while for mixes containing 5%, 10%, and 15% residue, the peak stresses are 22 MPa, 20 MPa, and 17 MPa, individually. Regardless of this decrease, the mechanical properties stay inside for specific applications, proposing that baghouse residue can be utilized successfully in non-basic primary layers of asphalts.
