Health condition monitoring system. Inside a number of campus asphalt roads, optical fibres and sensors will be installed to monitor the roads’ condition and the need of maintenance. In earlier experiments, the speed of the machines, the temperature and the mixture were measured, providing researchers with data on possible weak spots in the road. Experiments on campus roads are a bit easier than on public roads 'outside'. It is possible, for example, to use a maintance moment to introduce new sensors.
