The fracture toughness behavior of three heats of A36 steel was examined in terms of CVN response and K sub ic measurements at an intermediate rate of loading (i.e., one second rise time to failure). These results were contrasted with current AASHTO toughness requirements and heat or "H" testing frequency. It was concluded that "H" frequency testing could prove to be inadequate for fracture critical details. In such instances each piece of steel should be tested for tis CVN performance at the specification temperature. /Author/
