Micro surfacing is designed for application on asphalt pavements that have adequate structural capacity.
If an asphalt pavement is displaying structural distress, a different treatment should be selected. If an asphalt pavement is experiencing active rutting and/or shoving, it is not a candidate for micro surfacing.
Although micro surfacing is widely used in the preservation of good asphalt pavements, the treatment may also be used to address specific asphalt pavement distresses early on. Preservation solves asphalt pavement problems early and avoids more invasive measures that may be required later on.
Micro surfacing can be used on a variety of asphalt pavement types, and throughout the range of traffic levels:
Although micro surfacing is typically placed on asphalt pavements, concrete and brick surfaces can be treated as well. This requires the application of a tack coat.
To ensure success, the laboratory performing the mix design should be aware of your project’s application and use.
Micro surfacing has been placed successfully in all climate regions. It is important that the lab know where a micro surfacing project will be placed to provide the optimum Job Mix Formula.
