The research notes that Taconite-based pavement repair options provide such benefits as longer-lasting/more efficient repairs. Additionally, Taconite-based pavement repair is seen to provide important near- and long-term cost-savings, reduced traffic delays, and increased safety for drivers. Immediate use and deployment of Taconite-based pavement repair would include the repair/maintenance of Hot Mix Asphalt (HMA) and Portland Concrete Cement (PCC) pavements (e.g., pothole repair). The research, which involves laboratory and field tests, does comparative testing against propane/infrared-based (IR) heating for: a) wintertime utility access and/or repair of pavement; and b) hot in-place recycling of HMA. Also included are cost-benefit analyses, designed to aid decision-makers withn municipal, county and state governments, as well as the private sector.
