Snow and ice increase road maintenance costs. Winter road maintenance accounts for ~20% of State DOT maintenance budgets. State and local agencies spend more than $2.3 billion on snow and ice control operations annually. Each year, these road agencies also spend millions of dollars to repair infrastructure damage caused by snow and ice. This exploratory project is aimed at developing precast concrete with self-powering defrosting capability. Defrosting capability has long been shown to be effective in cement-based materials by resistance (Joule) heating, provided that conductive admixtures are used to reduce the resistivity. Short carbon fiber is the most cost-effective conductive admixture to greatly lower the resistivity, so that resistance heating becomes effective. Short steel microfiber is even more effective than short carbon fiber, but it is much higher in price. ]]> Wed, 22 Jan 2025 11:56:11 GMT https://rip.trb.org/View/2491005 Durability Assessment of Self-Sensible Ultra High-Performance Concrete (S2UHPC) for Infrastructure Rehabilitation Under Extreme Weather Conditions https://rip.trb.org/View/2475699 Fri, 20 Dec 2024 19:52:22 GMT https://rip.trb.org/View/2475699 Use of Innovative Sustainable and Durable Materials in Concrete Pavements https://rip.trb.org/View/2479868 Thu, 19 Dec 2024 10:42:42 GMT https://rip.trb.org/View/2479868 Greenhouse Gas Reductions Due to VT Clean Transporation Incentive Programs https://rip.trb.org/View/2440048 Thu, 10 Oct 2024 14:17:11 GMT https://rip.trb.org/View/2440048 Assessing Electric Vehicle Benefits in a Rural, Cold, and Mountainous Region https://rip.trb.org/View/2425460 Sat, 07 Sep 2024 11:56:22 GMT https://rip.trb.org/View/2425460
