Dunn Company performed three miles of Cold In-Place Recycling (CIR) for the Moultrie County Highway Department on CH16 (Wilborn Creek Blacktop) last week.

The CIR process consists of the on-site rehabilitation of the asphalt pavement with a single unit recycling train. This involves cold milling the pavement surface and remixing with the addition of asphalt emulsion to improve the properties, followed by paving the recycled material and compaction of the reprocessed material in one continuous operations.

The process eliminates the need for hauling of material to and from the site. CIR re-uses the county’s most viable assets, the roads in which they maintain. CIR drastically decreases environmental impact, and is a cost effective alternative to traditional construction.

Moultrie County Highway Engineer Jeff Birch was on site for CIR and noted the process was working well. CH 16 Wilborn Blacktop currently suffers from fatigue, edge cracking, longitudinal cracking, uneven surfaces, raveling, and has a very unstable ride. This is a process that should stabilize the road surface for the future.     Login or Subscribe to read the rest of this story.
