This Japanese Industrial Standard specifies iron and steel slag (here- a f t e r x r r e d to as “slag“) to be
3、 used for road bed and for heated asphalt mixture. Concerning the slag, there are two types, the blast-furnace slag which is generated in the pig iron manufacturing process, and the steel manufacturing slag which is generated in the manufac- turing process of steel. The blast-furnace slag is classif
4、ied by the difference of cool- ing process, into the blast-furnace slowly cooled slag and the blast-furnace water granulated slag. of manufacturing methods of steel into the convertor slag and the electric-furnace slag. In the slag to be used for road construction, there is the one which is manufact
5、ured for road bed material, as single or com- bination of the blast-furnace slag and the steel manufacturing slag as materials, and the one which is manufactured for the ag- gregates to be used for heated asphalt mixture and pitch stabiliz- ing process (heating mixture) using the steel manufacturing
6、 slag as material. The following Standards are cited in this Standard. Scope Remarks 1. The steel manufacturing slag is classified by the difference 2 . 3.
