Abstract: Based on the distribution of marble resources in China and the utilization of marble waste in Hezhou City, this paper analyzes the state-of-the-art marble waste resource re-utilization development in China and the existing waste accumulation issue in the current stone industry development process. In the view of effective utilization of the waste material, this paper analyzes the situation of marble waste reuse in the engineering applications domestically and overseas and proposes a suitable way for waste disposal in the Hezhou City. Throughout the basic material tests and subgrade bearing ratio tests, it is proved that the marble waste powder can be used as the highway subrade material under certain conditions. This conclusion can provide new ideas and references for the construction of roadway projects.

Key words: Marble Waste, Basic Physical Properties, Mechanical Properties, Subgrade Materials
