摘要

Roads are constructed worldwide and consistently bear heavy traffic and environmental loads, leading to early concealed distress and premature deterioration. To support the long-term performance monitoring of road infrastructure and enable early detection of concealed distress, this study introduced a novel MEMS (micro-electro-mechanical system) acceleration sensor, designed with the construction and service characteristics of road infrastructure in mind. A dedicated performance test framework is developed for road engineering applications. Based on the experiment design and test results, the developed sensor has a frequency monitoring range of 0.1 ~ 200 Hz, a resolution of 0.042 mg, and effective service life of 10 years, the sensing capability and reliability of which are good enough to monitor pavement. Embedded within a newly paved pavement, these sensors acted as key nodes in a comprehensive monitoring system. The analysis of pavement acceleration signals under vehicle movement demonstrated the sensor’s capability to accurately identify different vehicular excitations and monitor traffic information effectively. This research presents a novel approach to road infrastructure maintenance, incorporating cutting-edge sensing technology to enhance the durability of extensive road networks by facilitating the early identification of concealed distress and enabling timely preventive maintenance.
