Title
Staff Report for a Resolution to Accept the Work for the Annual Street Sealing 2016-17 Project, Project No. 2017.0070
Staffreport
SUMMARY AND RECOMMENDATIONS
This project installed approximately 10 lane miles of street surface sealing treatments to preserve and prolong useful pavement life.
Staff recommends the following action:
* Accept the work by American Pavement Systems, Inc.
* Authorize the City Manager to file the Notice of Completion
* Release the performance and payment bonds, and,
* Release the maintenance bond upon successful completion of the one-year maintenance period.
BACKGROUND
Street sealing is an annual maintenance activity that can prolong the useful life of existing pavement by 5 to 10 years, depending on the treatment. The treatments associated with this project include slurry sealing, asphalt rubber chip sealing, and micro-surfacing. These treatments involve the application of one or more layers of rock chips, crumb rubber chips produced by recycling used tires, and asphalt binders. The particular process is individually selected for each street based on the pavement condition.
The City was awarded a grant from CalRecycle in March 2016 for the use of crumb rubber chips in the rubberized chip seal process and will be reimbursed at a rate of $0.50 per square yard of roadway where that process was applied on this project. The City will be reimbursed $21,278 from the grant for this year's project.
Each year work is performed in one of the City's four maintenance areas. This year streets within the southern maintenance quadrant of San Leandro were evaluated for work. Priority was given to streets with the lowest pavement condition index that had not deteriorated to the point that replacement was required. The project installed approximately 5.0 lane miles of slurry seal and approximately 4.8 lane miles of cape seal.
ADA compliant curb ramps were installed under a separate contract on streets that received cape seal treatment.
