Texas legislation advocates use of EF slag on roads

PITTSBURGH — A Texas congressman is pushing state legislation that would promote the use of electric-arc furnace (EF) slag and recognize it as being as beneficial as blast furnace slag on roads.

House Bill 2293 and House Concurrent Resolution 70 would specify that EF slag would be acceptable for use in road construction projects, including for paving, bridge construction and other appropriate road construction.

The steel industry has been unsuccessful in its efforts with the Texas Department of Transportation to enable the use of EF slag even though this type of slag offers price and performance benefits, as well as conserving natural resources, according to the resolution introduced by Republican Rep. John Kuempel.

The Texas Department of Transportation already recognizes the merits of blast furnace slag.

EF slag has been proved to be environmentally safe and more stable than other aggregates used in road work, according to the legislation. EF slag has good adhesive properties because the slag particles interlock, which improves skid resistance, and as a renewable mineral resource the use of slag is cost effective and reduces the need to mine virgin aggregates.

The legislation has been forwarded to the Transportation Committee. If the measure is approved, it would become effective Sept. 1.
