Providing a smooth pavement for safe and efficient travel is one of the most important aspects of Mn/DOT's responsibilities. A Mn/DOT Statewide Smooth Pavement Task Force has been very active in addressing the issue of providing smoother, longer-lasting pavement surfaces. While the original focus of the task force was to eliminate potholes, current research projects include issues relating to slurry sealing, rough patching, crack sealing, and micro surfacing, etc. Experiments are being conducted in the winter and the summer months, trying to find the most efficient and economical patching and crack sealing methods in both cold and hot climates.
