Annual Street Maintenance - Winchester Boulevard Resurfacing
(Updated July 29, 2020)
Winchester Boulevard from the northern city limit line (approximately 171 feet north of Rosemary Lane) to the southern city limit line (at the intersection of Knowles Drive); and West Campbell Avenue from Winchester Boulevard to 82 feet west of the centerline intersection with Jeffers Way.
The project will resurface Winchester Boulevard from the northern city limit line at San Jose to the southern city limit line at the Town of Los Gatos. The project will resurface approximately 2.5 miles of pavement, upgrade all curb ramps to current ADA standards, and will have minor traffic signal work done. The project is a part of the City’s Pavement Management Program (PMP) designed to maintain city streets at levels of service expected by the residents of Campbell.
Week of August 3, 2020 through end of September, 2020
- Apply the Stress Absorbing Membrane Interlayer (SAMI), otherwise known as a rubber chip seal, to the existing milled street surface (day work.)
- Resurface the street with rubberized asphalt concrete (night work.)
- Utility adjustments to finished grade (day work.)
- Final striping installation (day work.)
The sheer magnitude of resurfacing a heavily traveled arterial street, like Winchester Boulevard, necessitates a multi-year delivery approach to design and construct; it requires combining funding over multiple fiscal years (FY). As such, the PMP is currently in the cycle of combining three FY of Capital Improvement Program (CIP) Annual Street Maintenance money for resurfacing Winchester Boulevard. The first year began in FY 17/18 when the design started for the project, and the third year will end in FY 2019/20 with completion of construction.
The project will resurface Winchester Boulevard from the northern city limit located 171 feet north of the centerline intersection with Rosemary Lane to the southern city limit located at the intersection with Knowles Drive, and W. Campbell Avenue from Winchester Boulevard to 82 feet west of the centerline intersection with Jeffers Way.
The project will cover the following aspects:
- Upgrade all existing curb ramps and passageways to comply with ADA standards;
- Repair uplifted/sunken curb & gutter, and root prune adjacent trees to re-establish flowline along
the gutter pan and eliminate ponding issues;
- Conduct traffic signal modification work as a result of installing ADA compliant curb ramps and
- Mill/grind-down the existing pavement; dig-out and repair isolated pavement failure areas; apply a
stress absorbing membrane interlayer (SAMI) / rubber chip seal; and resurface the entire area with rubberized asphalt concrete;
- Microsurfacing on Campbell Avenue;
- Restore striping, pavement markings and markers;
- Adjust various utility appurtenances to finished grade; and
- Perform public outreach to the local businesses/school/residents within a radius of 500 feet of the
To minimize construction impact on traffic, some paving work at major intersections may be performed outside regular work hours.
American Pavement Systems (APS), a subcontractor to MCK Services, will be applying a stress absorbing membrane interlayer (SAMI), otherwise known as a rubber chip seal, to the existing milled street surface the week of August 3rd through August 7th, 2020. The rubber binder used in the SAMI operation enhances the elasticity & flexibility in the existing pavement structure that is remaining; it also seals all the cracks, thereby creating a waterproofed surface. Aggregate chips coated with asphalt concrete are then embedded into the rubber membrane to provide a wearing surface.
After the SAMI is complete, MCK Services will then overlay/resurface the street with 1.8" inches of rubberized asphalt concrete. This work will start the evening of August 9th and is estimated to be completed by August 20th, 2020.
See SAMI & Overlay Work Notice for more information.
Once the street resurfacing portion of work is done, the Contractor will then adjust all utility appurtenances to finished grade, and will install new pavement striping, markers and legends on Winchester Boulevard and on W. Campbell Avenue. It is estimated that this portion of work will be completed by the end of September 2020.
