2021 is the first year of China's 14th Five-Year Plan and the first five years when China has embarked on a new journey to become a comprehensive and modern socialist country. Its meaning is self-evident. One of them will focus on green and low-carbon development, continue to improve environmental quality, improve the quality and stability of ecosystems, and comprehensively reform the utilization rate of resources. As a new round of transportation infrastructure construction to accelerate the further increase of building materials demand, large-scale solid waste recycling industrial production is on the agenda such as bulk solid waste, titanium slag powder not only occupies a lot of land resources, groundwater pollution, titanium slag powder in the natural environment also destroyed the environment, affect the sustainable development of economy. The so-called solidification material of titanium dioxide slag uses titanium dioxide slag, cement, curing agent, and lime as the main raw materials. After corresponding processing, a new type of titanium dioxide slag solidified soil is generated. Its mechanical properties and water resistance have reached technical requirements for pavement base application. This article focuses on the current situation of titanium dioxide slag, and in order to ensure the sustainable development of the industry, the application of road fluid new materials and their processes to improve and solidify titanium dioxide slag technology in transportation infrastructure engineering has achieved good results, truly turning waste into treasure. In view of the research results of this article, it is recommended that this technology should be promoted and applied in the future.
