Energy savings in transportation: Setting up an innovative SHM method

Abstract

Transportation systems are gradually changing. Innovative solutions are provided by automotive industries, construction firms, computer-aided pavement management systems, sensor-based structural health monitoring (SHM) systems, and international regulations. This calls for efforts and studies aiming at finding a trade-off between the ever-growing request of innovation (smart cities), and the never-ending depletion of resources and energy. Energy savings in road infrastructures can be pursued through: 1) construction process optimization; 2) traffic management improvement; 3) vehicle optimization; 4) recycling and reuse of construction materials; 5) innovative materials; 6) energy harvesting; 7) smart roads; 8) maintenance and rehabilitation optimization through SHMmethods and technologies. Theobjective of the study is to set up an innovative SHM method aiming at achieving energysavings in transportation in terms of Pavement Management System (PMS) optimization.The new method here setup was implemented through an experimental investigation. Amicrophone was placed on different road pavements, impulse loads were produced by aLight weight Deflectometer, LWD, and vibro-acoustic signals were recorded and analyzedin the pursuit of assessing the structural condition of the pavement. Using this knowledge toimprove the management process of transportation infrastructures, it is expected that safer,more resilient, and less energy-consuming assets will be provided.
