The original deteriorated concrete deck was replaced using high performanceconcrete (HPC), reinforced with low-carbon, low-corrosion reinforcing steel. HPC is a new technology in Arizona.This report documents the first survey of the deck's condition and recommends that ADOT embark on a monitoringprogram to evaluate the performance of HPC.The ADOT monitoring program should consist of visual observation of the deck condition and concrete samplingand testing to measure and document HPC performance. The survey presented in this report was performed onDecember 18, 2007, which represents the first field survey since concrete deck placement.Visual observation and test results show the following:1. The concrete has a very low chloride permeability.2. The concrete has significantly slowed down and/or prevented chloride penetration through the bridge deck.3. The average air-void parameters of HPC do not meet the industry standards for frost resistant concrete.4. The deck surface appears to have minimal wear from snow removal equipment and shows no signs ofconcrete cracking.HPC appears to perform very well during the monitoring period despite the lower than recommended air voidsystem. There were no signs of deterioration or adverse field conditions.It is recommended that bridge deck monitoring and concrete testing be done annually or biennially throughout thebridge's estimated 50-year service life to confirm long-term performance of HPC. It is also recommend that the nextmonitoring survey be initiated and conducted before the end of the year 2009
