Annual Street Sealing 2009-10 Award of Contract 2 July 19, 2010 This year's project will incorporate the use of an asphalt rubber chip seal application into the program. Rubberized asphalt products have been used by Caltrans and a few other agencies for several years. Asphalt rubber treatments are more flexible than standard treatments, keeping the surface waterproof by preventing the formation or propagation of cracks. While the application is more expensive than the standard chip seal products, it requires less preparation effort by Public Works Services street crews and can be used on streets in poorer condition that would typically require more expensive asphalt overlay repairs. Traffic noise is typically reduced when using rubberized asphalt and, as the materials used are made from recycled tires, this treatment also aligns with the City's goal of using "green" products. A double asphalt rubber chip seal will be applied to Farnsworth Street from Lewelling Boulevard to Vining Drive. This street segment was originally part of the scope of work for the Annual Overlay/Rehabilitation 2009-10 project, but the pavement condition was found to be ideal for a double asphalt rubber chip seal application, so this segment of Farnsworth Street is no longer scheduled for reconstruction.
