Research on Grading Features of Bituminous Steel-Slag Mixture

Abstract

To detect and analyze the chemical composition and physic-mechanical properties of converter steel slag of Jigang Group Co., Ltd and evaluate its feasibility as aggregate of the bituminous mixture. Use the steel slag as aggregate, mix the bituminous steel-slag mixture in three different grading structures, compare its physical and mechanical properties and analyze the influence of grading on the technical properties of bituminous steel-slag mixture. According to the test analysis results, determine the optimum grading structure suitable for bituminous steel-slag mixture, re-mix the mixture according to the optimum grading structure and verify its physical and mechanical properties, then based on this, propose reasonable grading range of AC20 bituminous steel-slag mixture.
