Ultra thin lift asphalt is a preservation treatment designed for pavements that have adequate structural capacity and proper drainage. Ultra thin lift asphalt can address minor cracking and raveling, but should not be applied to address extensive failures such as alligatored cracking, rutting or shoving. Roadways with inconsistent profiles can require thicker lifts and present compaction challenges.
Site selection for specific distress:
While ultra thin lift asphalt is typically applied to roads in good conditions, this treatment can also be used to address specific pavement distresses early on.
Ultra thin lift asphalt is typically applied to existing asphalt surfaces. Bonded wearing course, in which a heavy emulsion membrane is applied directly ahead of the application, is reccommended for application on higher volume and particularly on concrete surfaces.
Ultra thin lift asphalt can be applied in any climate zone. Due to the thinner application of typically no more than one inch in depth, it is recommended that thin lift asphalt be applied at higher minimum ambient and surface temperatures than traditional thicker asphalt mixes.
