Sustainable practices on campus road projects

Last summer, UCSC's Physical Plant worked on a number of road projects, including the McLaughlin Road Rehabilitation Project. During this particular project, construction crews used a technique called Full Depth Reclamation (FDR), which grinds existing asphalt, base rock, and native soil in place, mixes it with 3% dry concrete, and then compacts it into a sub-base. A new 3" asphalt overlay is then placed atop. By using this technique, Physical Plant reduced the amount of truck trips on and off campus as well as reduced the amount of new material needed to construct the road. What an awesome way to integrate sustainability into an important construction project!
