Feasibility of using copper slag as natural aggregate replacement in microsurfacing for quality enhancement: Microscopic and mechanical analysis
Graphical abstract Display Omitted
Highlights Different amounts of CS are used as replacement of aggregate in microsurfacing. XRF, FESEM-EDS, WTAT, LWT-displacement and LWT-sand adhesion tests were analysed. The use of CS increases the asphalt resistance against traffic loading and stripping. The physical and chemical characteristics of CS influence the microsurfacing performance.
Abstract Annually, considerable amounts of copper slag (CS) are produced worldwide, the disposal of which is a great economic and environmental problem. The use of recyclable industrial materials in pavements could help with maintaining the non-renewable materials while reducing the environmental problems. The work reported in this paper is based on a laboratory study performed to investigate the possibility of using CS at 0, 10, 20, 30, and 40% as partial replacement of aggregate in microsurfacing mixtures for the performance improvement and industrial waste reduction. The results showed a good potential for the use of CS in microsurfacing treatment. CS, especially at 30%, enhanced the asphalt performance concerning abrasion resistance, curing time, and vertical and lateral displacements due to its angularity and high percentage of Fe2O3 and SiO2. Also, regarding the analysis of variance (ANOVA), the CS was a more effective factor in curing time and deformations due to traffic loading than residual bitumen.
