Study on Asphalt Absorption of Steel Slag

Abstract:

Steel slag has been using as a substitution of natural aggregate, such as basalt and limestone, in road construction. But the huge asphalt absorption of slag has been a main obstacle to hinder the utilization of slag. But the detailed study in this area is still less. This paper investigated the asphalt absorption characteristic of steel slag. The results suggest that: the value of asphalt absorption of steel slag (AAOS, the weight of asphalt absorbed by per 100g steel slag) is much higher than the ones of limestone or basalt; AAOS increase slowly with the prolongation of storage time or the increase of storage temperature; the increase of viscosity causes a drastic reduction of asphalt absorption. The results also reveal that with the increase of asphalt content the AAOS value firstly increases and then decreases.
