    This report examines the fracture toughness behavior of three heats of A36 steel in terms of Charpy V-notch (CVN) and critical stress intensity level (KIc) at an intermediate rate of loading (that is, one second rise time to failure). These results are contrasted with current toughness requirements of the American Association of State Highway and Transportation Officials (AASHTO) and the “H” testing frequency.
