Construction and Operations Applications For Radio Frequency Identification (RFID) ...

... "A young technology with considerable commercial buzz, RFID – radio frequency identification – allows rapid and accurate reading of tags which, unlike UPC bar codes, can be read from a distance, in harsh environments, and through many materials without a direct line of site required. In uses that employ the small and increasingly inexpensive RFID tags, the radio signal sent in search of tags provides energy sufficient for a response from the tags, thereby eliminating the need for an internal tag power source. More intriguing and pertinent to highway construction is the use of RFID tags to monitor material properties. A materials engineer with Michigan DOT turned to the private sector for help developing concrete monitoring applications. A tag is embedded in concrete and monitors temperature, which data can be used to assess developing strength and curing rates for quality control." ...
