smart sensors, Fibre Bragg Gratings technology, asphalt construction process


The Fibre Bragg Gratings (FBG) technology based on integrated photonics, offers specific benefits including thermal mapping, damage detection, shape- and distributed sensing. This makes it useful for determining pavement behaviour during extreme weather conditions e.g. freeze-thaw cycles when harsh winter conditions could damage the asphalt surfacing layer. However, the harsh construction environment and traffic loading highlights the high-risk challenge of installing the sensor into the asphalt layer in a noninvasive manner so that the key parameters are accurately measured during and after construction.
