Bridges, buildings, highway pavements, and similar structures are               deteriorating at a rapid rate in the United States.  Methods to                 determine the amount of deterioration to a reasonable degree are not            available and, therefore, it is impossible to determine the remaining           life of the structure.  This project will investigate the use of x-ray          fluorescense and neutron/gamma detection to determine the internal              condition of materials in place.  The two methods are complementary and         will provide a range of capability for use on different materials.              Conditions to be evaluated are salt, moisture, location of voids,               reinforcements, effectiveness of desalination, and penetration of               preservatives or consolidants.  The results will be very useful to              evaluate the condition of existing structures and to determine when             repair, retrofit, or replacement may be necessary.
