Analyze Existing Fog Seal Asphalts and Additives

Project Description

Fog and rejuvenating seals have the potential to reduce and reverse the aging of asphalt pavements, reduce cracking and raveling, and provide a better, longer-lasting pavement. Pavements sealed within the last few years and new treatments were tested each year of the two-year study to determine the impact of these treatments on permeability, strength, binder viscosity, and depth of penetration. The project created guidelines on the best practices, selection of appropriate candidates, pre-treatment work, application rate and treatment type, application suggestions, curing time, and performance.
