Travel on state Highway 84 (Woodside Road) over the 12 miles between Interstate 280 and Friars Lane will be one-lane at times in August and September as crews repair and repave damaged asphalt.
A new feature will come with the new surface: an overlay of rubberized asphalt concrete, with benefits that include less noise by passing vehicles, greater skid resistance, and the recycling of old tires that would otherwise go to a landfill.
Road crews will start preparing the road for repaving in the first week of August, and the actual paving should begin a week or two later, California Department of Transportation spokeswoman Gidget Navarro said.
Work in the vicinity of Woodside Elementary School, which reopens Aug. 23, is expected to take one day and "should be completed by start of school," Ms. Navarro said. If not, she added, the crews would work at night, reopening the lane under repair before the school day begins.
Weekdays work hours will be from 7 a.m. to 6 p.m. There will be no weekend work, but nighttime work, from 7 p.m. to 7 a.m., may occur occasionally along Woodside Road between Canada Road and I-280, Ms. Navarro said.
Caltrans is asking drivers to proceed with caution through construction zones.
Chances of Woodside Road being closed are nil, Ms. Navarro said. Flaggers will be on hand to control traffic. The work is not expected to impact weekend bicyclists and beach-goers, and pedestrians and equestrians in general, she said.
There may be more noise as a work shift gets going, particularly from grinding and paving machines and "mandatory" backup alarms, she said.
Riding on rubber
A rubberized asphalt surface improves the ride and extends the road's service life, Ms. Navarro said. It's also cheaper for the state, according to a discussion of the technology on the website of the Department of Resources, Recycling and Recovery.
While rubberized asphalt is more expensive per ton, tests have shown that the thickness of the surface can be reduced by half. Repaving with a 4-inch layer of ordinary asphalt is 81 percent more costly than doing the same thing with a two-inch layer of rubberized asphalt, the department says.
In addition to skid resistance, noise reduction and the tire recycling aspect, the benefits of rubberized asphalt include a hardier surface than ordinary asphalt, and less spray when driving over water on the road, which can improve visibility, the department says. Noise-reduction effects start off strong, but fade over time, they say.
