The effective use of converter furnace slag has not been made yet, as it has extraordinary expansive nature due to the hydration of free CaO. In this paper, it has been made clear that the expansive nature is reduced greatly by the method of steam aging and two types of new upper base materials using the improved converter furnace slag have almost the same properties as those of HMS-25, whichis the ordinary upper base material made of blast furnace slag. Furthermore, the results (CBR test, plate bearing test and Benkelmann beam test etc.) of the tentative pavement test with the two types of new upper base materials are concerned.
