Study on standardized testing methodologies for embedded pavement status sensors

This paper proposes the standardized testing methodologies for embedded pavement status sensors based on the road weather meteorological environment monitoring and service requirements. A large number of possible testing procedures were developed for measuring pavement surface temperature, sensor moisture state and the water film thickness. In a year and a half of the time, three factory embedded pavement status Sensors are tested, the outdoor data in different environment including rainy, snowy, sunny and freeze days is analyzed. The test results verify the accuracy, maneuverability and repeatability of the testing technology, and the standardized testing methodologies will fill the blank of domestic pavement status sensors testing methodologies, improve the efficiency of the highway maintenance and highway management, avoid highway traffic delay, reduce the traffic accident due to bad weather.
