RFID sensors to measure the energy consumption of warm mix and recycled asphalt

Governments, regulatory bodies and road authorities all push for and promote sustainability. Contractors respond with strategies to reduce their carbon footprints. Besides optimising their asphalt production and logistics processes, companies are investing in the development of low energy asphalt mixes. Warm Mix Asphalt (WMA) is such an asphalt...

Smart sensors in asphalt: monitoring key process parameters during and post construction

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...
