Environmental Pavement Monitor

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. This SBIR will develop a sensor that can be embedded within concrete or asphalt, which can measure moisture, temperature, stress and strain. 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. Data obtained from these sensors will result in longer service life, lower infrastructure costs, and the development of more effective means of remediation. The device will be interrogated using radio frequency energy returning a unique identification number so that data can be correlated with sensor location. High temperature resistant electronics will be adapted to an existing sensor platform to ensure the device can withstand the temperatures encountered in asphalt mixing.
