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 Evaluation of Chlorides on Soil and Structural Elements https://rip.trb.org/View/2431160 Mon, 16 Sep 2024 08:31:55 GMT https://rip.trb.org/View/2431160 Assessing the Sensitivity of Colorado’s Mountain Landscapes to Road Salt: Guidance for Sustainable Winter Road Management https://rip.trb.org/View/2417307 Wed, 14 Aug 2024 12:20:45 GMT https://rip.trb.org/View/2417307 Alternative Deicer Performance Characterization: Know Before the Snow https://rip.trb.org/View/2398086 Thu, 27 Jun 2024 17:00:21 GMT https://rip.trb.org/View/2398086 Remediation of Deicer Salt Contaminated Soils using Native Montana Plants https://rip.trb.org/View/2342033 Mon, 19 Feb 2024 17:14:22 GMT https://rip.trb.org/View/2342033
