Abstract:

This instructor's guide is designed for a 2 to 4 hour long workshop on design, construction, and performance of micro-surfacing. This workshop will be useful to Federal Highway Administration, State, and local highway agency engineers who require knowledge of micro-surfacing. Micro-surfacing consists of polymer-modified asphalt emulsion, 100% crushed aggregate, mineral filler, water, and field control additives as needed. Micro-surfacing is primarily used to improve surface friction and to fill wheel ruts. When properly designed and constructed, it has shown good performance for 4 to 7 years. Since micro-surfacing is applied in a thin layer, 10 to 15 mm, its use should be limited to structurally sound pavements. The one unresolved engineering issue concerning this technology is the lack of standard mixture design test procedures. Although the current testing procedures have resulted in micro-surfacing systems that have generally provided good performance, there is a need to further refine the existing test procedures and adjust design standards to better reflect the effect of various mixture components. Standard mixture design procedures and State acceptance criteria will further enhance the acceptance of this promising technology by the highway community.
