CIR a Hit in L.A.

The Los Angeles County Department of Public Works has used cold asphalt recycling methods on a number of projects in recent years, saving over $3 million as compared to the hot mix asphalt process. Many of the projects used cold-in-place recycling (CIR), a method involving mobile asphalt recycling trains that move down the road and recycle material in place. In the spring of 2012, a three-quarter-mile CIR project began on Altadena Drive. A total of 1.5 inches of asphalt was milled off the road, then replaced with a three-inch CIR treatment. The project saved the county an estimated $109,000 compared to the use of hot mix. A larger project at Upper Big Tujunga Canyon Drive saved an estimated $1.2 million. CIR has been shown to be beneficial, both in its reduction of greenhouse gases and in cost savings.
