From page 1...
... This report documents the state of the practice of this pavement preservation and maintenance tool and identifies critical knowledge gaps that could be filled by additional research. The objective of this synthesis is to identify current practices in microsurfacing that highway maintenance practitioners report as effective in addressing specific pavement preservation and maintenance problems.

... The synthesis identified two effective practices in microsurfacing project selection, three in design, four in contracting, and six in construction, as well as three more that came from the case study analyses. The most significant are: • Agencies in northern climates can mitigate potential quality issues induced by a short microsurfacing season by requiring a warranty.

From page 3...
... • The lack of rigorous field tests based on a rational quantification of measurable microsurfacing properties leads to a suggestion for research to develop a suite of field tests that allow an inspector to test the microsurfacing mix after it has been laid as well as tests to identify when the mix has cured to a sufficient degree to open it to traffic without fear of damaging it. In conclusion, the synthesis found that microsurfacing is being used successfully on a routine basis across North America.
