Smart and Environmentally Friendly Winter Maintenance Solutions for Safe Winter Mobility

项目名称：	Smart and Environmentally Friendly Winter Maintenance Solutions for Safe Winter Mobility
摘要：	The primary objective of this study is the investigation of different types of fibers and fiber dosages on conductivity properties of paving concrete, and ultimately evaluation of deicing efficiency. To do so, an experimental matrix with seven concrete mixtures was developed. A conventional paving mixture was selected as a Control mixture. The remaining six mixtures were designed with carbon and steel fibers at 0.25 %, 0.50% and 0.75% volumetric dosages. Concrete specimens will be cured for 28 days in a fog room after which they will be tested for compressive strength, flexural strength, and toughness index. To assess the electrical properties, electrical resistivity will be measured on 14-, 28-, 49-, 70-, and 90-days age. Additionally, a series of specimens will be cast with electrodes and connected to DC power supply to assess the current flow. This comprehensive experimental framework will enable to determine optimum percentages of carbon and steel fibers which will reduce the electrical resistivity of concrete significantly. As a result, the concrete will gain enough electrical conductivity that will enable current flow and heat development necessary for the intended purpose of pavement deicing.
