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

This study should determine the pros/cons of each method and determine the benefit/cost of applying a higher AFT versus a chip seal at year 1. The project will include testing/showing test results on how much asphalt is coating each rock and determine the optimal AFT. It will evaluate if there is a benefit of doing both at the same time and determine if it is better to spend more money upfront (paying for the higher oil content) versus applying the seal coat at year 1.
