    About this Project
    Brief Project Description & Background
    This feasibility study is focused on the application of nanotechnology in concrete pavements and bridge decks. The main goal of the study is to improve the wearing resistance of concrete. Three candidates of nano materials are considered and the best one or two are recommended for further investigations on their effects on other mechanical and chemical properties.
    Research Objective
    The objectives of this study are to characterize the effects of nano-materials on the wearing resistance of concrete surface and to recommend one or two nanotechnologies for further investigations on their effects on other mechanical and chemical properties of concrete pavements and bridge decks.
    Potential Benefits
    The availability of such a technology may potentially improve the comfort level of passengers, the safety of highway operations, and the efficiency of fuel consumptions, which addresses the main MATC theme topics. It may also reduce the emission of CO2 associated with the poor condition of roadways.
    Abstract
    This proposal is focused on a feasibility study on the use of nanotechnology in concrete to improve the wearing resistance of concrete. Three candidates of nano materials are considered: nano TiO2 particles, nano carbon-tubes, and polyurea cross-linked aerogels. The tensile and compressive properties and the wearing resistance of concrete will be evaluated for various mix designs. The optimal amount of nano material additives will be determined following the ASTM standard test methodologies. The test results from three types of materials will be compared for their mechanical behaviors, including wearing resistance. The best practice in concrete application will be recommended in terms of technological, economic, and social benefits. The availability of such a technology may potentially improve the comfort level of passengers, the safety of highway operations, and the efficiency of fuel consumptions, which addresses the main MATC theme topics. It may also reduce the emission of CO2 associated with the poor condition of roadways.
