Interpretation of the Magnetic Field Signals Emitted by Encoded Asphalt Pavement Materials Leiva Padilla, Paulina Moreno Navarro, Fernando Manuel Iglesias Salto, Guillermo Ramón Rubio Gámez, María Del Carmen Encoded asphalt materials Smart roads Road-to-vehicle Infrastructure-to-vehicle Asphalt materials modified with different types and dosages of magnetically responsive materials can emit patterns of magnetic signals easily detectable by magnetic field sensors. These patterns could be used to encode roads and improve infrastructure-to-vehicle (I2V)/road-to-vehicle (R2V) communications. In this sense, this paper presents a laboratory study addressed to analyze the magnetic field signals emitted by encoded asphalt specimens manufactured with various dosages of steel fibers. The analysis consisted in the evaluation of the influence of three parameters: (1) the height of placement of the magnetic field sensors, (2) the approach speed of the encoded specimen/vehicle and (3) the distance from signal detection. Results show that, for each one of the parameters evaluated, there is a limit value below which it is possible to work with the magnetic signal emitted by the encoded samples. A proof of concept was used to validate the results obtained. 2020-11-24T11:58:59Z 2020-11-24T11:58:59Z 2020 journal article Leiva-Padilla P, Moreno-Navarro F, Iglesias G, Rubio-Gamez MC.
