The heterogeneous nature of concrete necessitates a statistical approach in order to extract quantitative information from the measurements. It is anticipated that the research will lead to new techniques for assessing damage in concrete ties. The proposed research also will have significant impact on the educational training of one graduate student in nondestructive evaluation techniques applied to essential infrastructure materials.]]> Wed, 24 Jul 2013 01:02:21 GMT https://rip.trb.org/View/1257014
