Environmental Pavement Monitor

<p>With infrastructure costs escalating it is becoming essential to monitor the health of asphalt and concrete pavement so that timely maintenance can maximize their usefulness.&nbsp; This SBIR will develop a sensor that can be embedded within concrete or asphalt, which can measure moisture, temperature, stress and strain.&nbsp; It will provide critical data for evaluating pavement performance starting with the initial quality control period of freshly mixed or freshly cast, through its useful service life.&nbsp; Data obtained from these sensors will result in longer service life, lower infrastructure costs, and the development of more effective means of remediation.&nbsp; The device will be interrogated using radio frequency energy returning a unique identification number so that data can be correlated with sensor location.&nbsp; High temperature resistant electronics will be adapted to an existing sensor platform to ensure the device can withstand the temperatures encountered in asphalt mixing.</p>
