Pavement Preservation is a preventive maintenance program that involves repaving the roadway in order to extend its service life. The subject project on Interstate 95, between Guilford and Old Saybrook, involved two different types of Pavement Preservation. The first type of preservation, applied between exits 58 and 65 and between exits 68 and 69, consisted of the removal (milling) of the top 3 inches of roadway followed by repaving using Warm-Mix Asphalt technology. Warm-Mix Asphalt is a process by which the pavement is not required to reach such high temperatures to be placed on the roadway, making compaction easier (resulting in better performance and reduced greenhouse gas emissions), reducing paving costs, and extending the paving season. The second type of preservation, applied between exits 65 and 68, consisted of using an Ultra-thin pavement to create a smoother riding surface that reduces friction, rain splash, and noise. Construction for this project began in June 2012 and was completed in September 2013.
