All year round the roads are subject to strong climatic variations. In winter, partial or total freezing and thawing cause significant damage to the asphalt mixes: heaving, cracks, subsidence, potholes, etc.
The temperature, the length of the freeze-thaw period and the speed at which frost penetrates the asphalt are all factors influencing the sensitivity of the pavement and favoring the appearance of distresses. For the companies in charge of the construction and maintenance of road networks, being able to know the temperature of the ground in order to anticipate the thermoplastic behavior of the asphalt and thus to manage the road stock in the best possible way is a real challenge.
For example, in Quebec, where climatic conditions are extreme, roads suffer particularly from this phenomenon and degrade twice as fast as in temperate zones.
With the TEMP2S temperature sensor and its two remote probes, it is possible to measure the temperature of the ground at two different depths and thus obtain an indication of the depth of freezing and thawing of the roadway. The accuracy of this temperature sensor and its amplitude allows to obtain reliable and usable data throughout the seasons.
The solution deployed with the TEMP2S sensor will provide real-time information on the behavior of the road surface and anticipate its evolution. The study of the results obtained will also enable specialized companies to develop an asphalt that is resistant over time, adapted to the environment in which it is located and to meteorological changes.
