|The 2013 Overlay Program will cost an estimated $3,500,000 with the majority of the work on these arterial roadways:
- Northup Way from 140th Ave NE to 173rd Ave NE;
- 156th Ave SE north of SE Eastgate Way;
- SE Eastgate Way east of 148th Ave SE;
- 164th Ave SE north of Lakemont Blvd; and
- Factoria Blvd, from SE 36th to SE 41st.
ADA ramp reconstruction and paving will begin in May.
Bellevue's street overlay program provides major street maintenance, which includes street overlays, pavement rehabilitation, curb, gutter and sidewalk or walkway repair, bridge condition inventory and maintenance, and appropriate Americans with Disabilities (ADA) retrofit work. It also includes pavement markings and vehicle detection for proper operation of our traffic signal system. overlay video
When streets are overlaid, old asphalt is milled/ground down so the new overlay will match the concrete curb and gutter. A week or so later (weather depending), a paving machine lays down two inches of new asphalt, followed by a heavy roller that presses the asphalt into place. overlay process details
When streets are regularly maintained, the city is able to keep them in a safe condition and generally will only need to replace the top layer of asphalt in its annual overlay program. If a roadway is neglected too long, all of the old asphalt must be removed, then replaced by six to ten inches of new asphalt depending on the roadways type and level of use. This complete rebuild can cost up to three times as much as an overlay.
How are streets chosen for overlay?
Projects are selected through the Pavement Management System, which selects roadway candidates from the city’s 942 lane miles for maintenance at the most cost-effective time in the pavement’s lifecycle. It prioritizes the streets based on their functional classification (neighborhood/residential, arterials, etc.), roadway defects and current street ratings to create a five-year overlay plan.
For its annual overlay program, the city each year allocates a certain amount of dollars to pave roadways.
Overlay Coordination with utilities in the roadway
Once determined, the five-year candidate plan is coordinated with the city’s Utilities Department and cable, gas and power franchise utilities companies to allow them to construct any upgrades to their facilities prior to any scheduled pavement overlay construction. By coordinating our plans with these utility projects, we avoid having recently resurfaced streets dug up and the longevity of the new pavement surface compromised. This is one of the main reasons drivers will see work in the roadway before a pavement overlay job.
There are many items of work to overlay a roadway and each require time to perform. Our goal is to perform the work as efficiently as possible however, there are many factors that influence how long these activities may take such as weather, size of the location, equipment and labor availability, materials availability and unknown site conditions that change how the work is to be performed.
The location of the paving is also very important. In a very congested area, it is difficult for the traveling public to get through the jobsite, which also increases the time it takes for the asphalt trucks to get to the paving machine which increases the time needed to complete the paving. Given there are many variables with this work, here are some approximate timeframes for the milling/grinding and paving operations that could be expected for a typical location:
- 1-2 working days for milling/grinding.
- 1-2 working days for paving a residential street.
- 3-5 working days for paving an arterial street.
During the repair and resurfacing of the roadway, flaggers and police officers will direct traffic through the construction site or detour motorists to predetermined routes around the site.
Typically, notification signs are placed in areas prior to work being performed to alert the public of the upcoming paving operation. These signs also keep the public from parking in the area of work so when our construction crews arrive at the location, they can do their work as efficiently and timely as possible. For work on major thoroughfares and intersections, variable message boards may be used to provide information to the public.
