A better understanding and comparison of the benefits of higher Asphalt Film Thickness (AFT) and chip seal is needed to inform pavement maintenance techniques and to optimize cost effectiveness. The research should include a benefit-cost analysis at 1 year of service life and explore the benefits of implementing both treatments at the same time.
State Aid Pre-Screening Meeting input:
Benefits of higher AFT (Asphalt Film Thickness) vs a chip seal at year 1. Conduct a cost-benefit analysis. Is there a benefit of doing both at the same time? Is it better to spend more money upfront and pay for oil content? There is a study in process with the university about bituminous)
