Identification of Hybrid Polymer Material STERED and Basic Material Properties Used in Road Substructures or Pavements

Abstract

Modern road construction uses a large number of polymer-based materials. Material composition depends on their roles. Among the most important functions of road body materials is to transfer all loads safely to the subgrade. A thorough understanding of material properties in various climates is crucial for this purpose. In the automotive industry, polymer residues from recycling can be used to make innovative materials, such as STERED, a hybrid polymer composite. Drawing on the porous nature of this material, this paper investigates its mechanical behavior. For road construction, the compressive properties of the material are most important. The paper presents the results of a detailed analysis and experimental research of the STERED material from in-lab tests. Successful research will lead to the inclusion of the material in road body compositions with excellent retention properties, vibration damping, and potential in circular economy.

A Novel Finite Element-Based Method for Predicting the Permeability of Heterogeneous and Anisotropic Porous Microstructures

“…In science and engineering, permeability is a very important physical property of porous media because it controls the directional movement and flow rate of fluids in the porous structure. Porous materials can be natural, such as soil and rock, or synthetic, such as a dense network of fibres or open-cell foams [ 2 ]. Permeability is influenced by factors such as the pore structure, through its size distribution and tortuosity, and the type of permeating fluid.…”
