Title:

The Monroe, Michigan Chip Seal Case Study: An Evaluation of Multiple Chip Seals’ Cold Weather Field Performance

Abstract:

The purpose of the Monroe Chip Seal Case Study was to evaluate chip seal performance for multiple test sections comprised with different asphalt emulsion – aggregate type combinations with emphasis on aggregate retention, especially during winter months. Different emulsions and aggregates were desired to be evaluated to determine if there was an optimum combination for performance in this climate over the course of one winter. Specific comparisons of interest in this project included: (1.) Neat (non-oil) emulsions versus emulsions with low oil additives, ( 2.) Modified emulsions with latex styrene butadiene rubber (SBR) versus modified emulsions with styrene butadiene styrene (SBS) and ( 3.) Limestone aggregate retention versus crushed gravel aggregate retention. Aggregate retention was measured through imaging analysis. Photographs were taken at identical locations monthly between September 2009 and April 2010. The change in aggregate coverage was measured over time by converting the photographs into black and white binary images. The binary images allowed for the calculation of aggregate coverage. Major findings of the research include that adding 1.0% #2 fuel oil to an anionic high float emulsion improved performance (aggregate retention) over emulsions without oil. Anionic limestone chip seals outperformed anionic gravel chip seals. No appreciable difference between limestone and gravel cationic chip seals was observed. There was no significant difference between latex modified and tyrene butadiene styrene (SBS) modified chip seals for gravel seals. Limestone seals with latex modified emulsion performed slightly better than SBS modified chip seals.
