From the work that has been performed in Phase 1 of the Ultra-Thin Bonded Wearing Course (UTBWC) Snow, Ice, and Wind Effects TRS, we understand that UTBWC pavement occasionally experiences negative pavement performance attributes in cold weather, requiring additional maintenance (beyond typical treatments) to remedy. Observations indicate a phenomenon of ice build-up, potentially due to the accumulation of wind-blown snow, melting and freezing of the wind-blown snow, and bonding of the frozen ice/slush to the underlying pavement. Through project development in Phase 1, the Technical Advisory Panel (TAP) has identified that additional data and cost collection (without any field instrumentation and/or laboratory testing) would be beneficial to the research which was the objective of this TRS. The field instrumentation and/or laboratory testing was suggested to be performed under Phase 3 of this study. This report can be viewed at http://dot.state.mn.us/research/TRS/2019/TRS1904.pdf
