Title
Pavement Rejuvenator - Eagle Ridge Subdivision
History
A portion of the Eagle Ridge subdivision was paved this past November as part of the 2023 Neighborhood Roadway Improvement Program. The snowplow assigned to this subdivision has both a front plow and an antiquated belly plow. During a snow event this past January, this use of the belly plow in conjunction with front plow resulted in scraping of the top layer of asphalt that is unsightly but also exposed aggregates to possible small pockets for water to freeze/thaw.
Public Works has since chained and put out of service the two remaining belly plows in the fleet and staff have been informed not to use them. The two vehicles are also being the first to be replaced with no new orders with belly plows.
When Public Works leadership identified the scraped asphalt, they sought confirmation from a licensed geotechnical engineer, CGMT. CGMT confirmed the plow damage consisting of stripping of the surface asphalt content and exposing aggregates and some seams. The structural integrity remains intact, but this type of distress requires corrective action to prevent accelerated pavement failure during future freeze/thaw cycles from moisture penetration into the mat and ice expansion. The geotechnical consultant recommended a surface asphalt rejuvenation process to preserve the integrity of the roadway. The product recommended was Reclamite.
Staff researched various topical pavement preservation products used in the Chicagoland area and determined that Reclamite would be a cost effective way to address the Eagle Ridge issue. In addition, staff saw the potential for an additional preservation tool of the annual Neighborhood Roadway Improvement Program. While Eagle Ridge would be applied this year, for other areas in the Village, it would be normally applied around 6-10 years to extend the life of the road.
The Reclamite product is one of the most popular pavement rejuvenator products used throughout the Chicag...
