The forthcoming ASTM E3013, Test Method for Evaluating Concrete Pavement Dowel Bar Alignment Using Magnetic Pulse Induction, will reinforce quality control and quality assurance measures behind durable, smooth mainline highways and airport runways. New to North America, magnetic pulse induction a) measures steel dowel alignment in concrete pavement joints, where the bars transfer loads from one slab to the next; and, b) yields data with which agencies or owners can determine if the dowel installation meets project specs.
