Abstract

Abstract

Taking the high-titanium heavy slag in Panxi area as the research object, the feasibility of using it as aggregate for asphalt mixture was analyzed through theoretical and experimental research, also it was compared with the natural stone such as basalt commonly used in asphalt mixture at present. The results show that the surface morphology of high-titanium heavy slag is rough and porous, and it is alkaline aggregate. Its adhesion performance with asphalt is better than that of natural stone, and its adhesion grade is grade 5. High-titanium heavy slag is a five-element slag system, belonging to low calcium and titanium-rich slag and low active slag, with good volume stability and high-temperature stability. High-titanium heavy slag has excellent particle morphology, mechanical properties and durability, but its density is slightly lower than that of natural stone and the water absorption is higher. The comprehensive performance of high-titanium heavy slag as aggregate of asphalt mixture is no worse than natural stone, and it has obvious environmental and economic benefits.
