JIS A 5015:2013 PDF Download

The JIS A 5015:2013 standard specifies the iron and steel slag that is used for the base course and hot laid asphalt mix in roads. The standard distinguishes between two types of iron and steel slag: blast furnace slag and steelmaking slag. Blast furnace slag can be further categorized into air-cooled blast furnace slag and granulated blast furnace slag, based on the cooling process used. Steelmaking slag, on the other hand, is classified into convertor-system slag and electric furnace-system slag, depending on the method of manufacturing steel.

This standard emphasizes the use of iron and steel slag in road construction. It also highlights the use of blast furnace slag and steelmaking slag, either individually or in combination, as materials in the manufacturing of base course materials. Additionally, steelmaking slag is specifically mentioned as a material for the aggregates used in hot laid asphalt mix and bituminous stabilization.
