Title
Staff Report for a Resolution Approving the Plans and Specifications and Calling for Bids for the Asphalt Rubber Street Sealing 2011-12 Project, Project No. 11-144-38-332
Staffreport
SUMMARY AND RECOMMENDATIONS
This project provides for the application of preventive maintenance treatments on various streets in San Leandro. The current program will concentrate primarily in the 2012 Asphalt Maintenance Area.
Staff recommends approval of the plans and specifications and calling for bids for the subject project.
BACKGROUND
City staff conducts an annual pavement condition survey using our Pavement Maintenance System to establish the condition of City streets. Based on this survey, various City streets are recommended for one of three maintenance treatments: reconstruction; overlay; or sealing. Sealing is the recommended treatment for streets in fairly good condition to rejuvenate and prolong the life of the pavement. Sealing treatments to be used may include: 1) slurry seal; 2) microsurfacing; 3) scrub seal; and 4) asphalt rubber cape seal.
The City of San Leandro is divided into four Asphalt Maintenance Areas, which allows Engineering and Transportation staff and Public Works Services staff to coordinate their activities to ensure an efficient use of resources to maintain City streets. The streets scheduled for this project are primarily in the 2012 Asphalt Maintenance Area (see attached map).
All street segments associated with this project are scheduled to receive an application of asphalt rubber chip seal. There are only a few contractors in California who can apply asphalt rubber chip seal. Therefore, streets that are scheduled to receive non-rubberized treatments this year will be done as part of a separate project to allow more contractors to bid on the work.
