Benefit/Cost of Applying a Higher Asphalt Film Thickness (AFT) vs. Doing a Chip Seal at Year 1

Status:  Active
Project Start Date:  07/20/2020


In Minnesota, reducing the influence of oxidation is a continuous challenge. Researchers will compare the effectiveness of two different methods: applying a surface treatment (typically a fog or chip seal) and increasing the asphalt film thickness during original construction.
