| 摘要： | 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 (FHWA), State, and local highway agency engineers who require knowledge of micro-surfacing. Micro-surfacing consists of polymer-modified asphalt emulsion, 100 percent 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. |
