The City of Dublin is testing a road resurfacing technique known as Cold In-Place Recycling (CIR). This process uses the existing pavement and a chemical mix instead of traditional hot-mix asphalt. By reusing the existing asphalt, CIR reduces the amount of materials that need to be transported to the site for paving. This saves money, emissions and energy. The City is testing the CIR process on Rings Road, west of Cosgray Road, as part of the 2018 Street Maintenance Program.
CIR is new to central Ohio, but is becoming increasingly popular in other locations because of its cost-saving and environmental benefits. The process has demonstrated a 20 to 40 percent cost savings, as compared to traditional mill and fill treatments. The CIR process also uses far less energy – up to 50 percent in some cases according to research done on other projects.
Dublin will evaluate both the short and long-term benefits of CIR to determine whether to use it in future road maintenance projects.
