New safer pavements in extreme temperature conditions


The PAVIREX project, “New safer pavements in extreme temperature conditions”, was co-financed by the Ministry of Science and Innovation and FEDER Funds, through the INNPACTO 2011 call. The consortium of the project is formed by CARTIF, Grupo Campezo, Euroestudios , Proas (Cepsa), Eiffage, the University of Oviedo and the University of the Basque Country.


The main objective of the project is the development of specific bituminous mixtures with improved response to extreme temperatures and situations, such as the formation of ice on the road.

An intelligent predictive system based on data acquirers will be developed, capable of offering the probability of short-term ice formation, with the objective of proceeding with the warming of the road by means of preheated fluid pipes and avoid the formation of ice.


    A CARTIF anti-ice prototype of 25 x 3.5 m2 has been developed, consisting of three independent modules of 5 x 3.5 m2 each, with different tube distributions and different mixtures. A geothermal installation has been used to raise the water temperature. In order to power the intelligent predictive icing system, the weather conditions on the roadway and the temperatures inside the asphalt mixture and the circuit water have been sensed

    Expected results

    • Development of new materials, including new modified binders from additives that give the bituminous mixture a better response to ice situations.
    • Development of a road heating system using geothermal hot water pipes embedded in the asphalt mixture, together with an intelligent predictive system, based on the sensorization of the roadway and the existing atmospheric conditions, capable of offering the probability of ice formation at short term.

    Currently, inspections of road and rail tunnels are carried out manually. CARTIF and Geocisa have studied how to implement technologies that allow inspecting automatically tunnels to achieve its preventive maintenance, developing a system which is able to organize the collected data.
