Abstract:

The goal of this study was to evaluate the effectiveness of using lignin from hydrothermally carbonized rice husks in asphalt materials as a renewable paving material to partially replace a fossil fuel-based binder. The study was conducted in close collaboration between Louisiana Tech University (LTU) Louisiana State University (LSU) and University of Oklahoma (OU). The research team at LTU, extracted lignin from rice husk, prepared modified binders and conducted a series of rheological assessments of the modified binders. The properties and performances of the asphalt mixes prepared with lignin-modified binders were evaluated at LSU and OU. The modification of asphalt binder with lignin exhibited an increase in the rutting resistance in comparison to the neat binder. The low-temperature properties of the asphalt binder were slightly impacted by the addition of lignin. The stability of the binder was found to be significantly enhanced by reducing the lignin particle size along with styrene Butadiene Styrene (SBS) modification. The modification of binder with lignin improved the rutting and moisture-induced damage resistance of asphalt mixes, however, cracking resistance was reduced with lignin addition. The findings indicate that a partial replacement of fossil fuel-based binder with lignin may be feasible but needs further work.
