Prediction of Fatigue Life of Steel-Slag Asphalt Concrete Based on Four Point Bending Test

Abstract:

Steel slag reserves of our country has reached 200 million tons and each year it will increase 100 million tons. Slag accumulation occupied a large number of enterprises space and made pollution to the environment. Since steel slag based asphalt pavements have been utilized for a certain history, their fatigue life necessitates comprehensive investigation imperatively. In this paper, the fatigue life of steel-slag asphalt mixture was tested through the four-point bending test. The results showed that steel slag prepared mixture was superior to limestone mixture after several freeze-thaws, with respect to moisture sensitivity, and was suitable for asphalt treated base (ATB). The fatigue life of slag asphalt mixture with low content limestone was longer.
