| 摘要： | Ultra-Thin Bonded Wearing Course (UTBWC) pavement surfacing was introduced to Minnesota in 1999 under the brand name, 鈥淣ovaChip鈥? It was developed as a preventative maintenance option to extend pavement life by placing a thin open/gap-graded hot mix asphalt (HMA) lift over a polymer-modified asphalt emulsion. The open/gap-graded aggregate also provides superior safety benefits under wet pavement conditions but safety benefits under snow and ice conditions recently have been in question. The objective of this Transportation Research Synthesis (TRS) was to investigate UTBWC snow, ice, and wind effect through performing a literature review and conducting interviews and information solicitations regarding experience with ice and snow control on UTBWC pavements. In addition, the available field instrumentation and/or laboratory testing that can be utilized on UTBWC test sections to address findings from this TRS were introduced. |
