This project was identified as a city priority during the FY 16/17 budget planning process. Staff requested Measure F funding allocation in order to mobilize the crack filling program for the purpose of raising the Pavement Condition Index (PCI) from 69 to 70 on city-owned streets.
15 – 20 miles of local streets and roads treated in various locations throughout the city.
Cost savings. Crack filling helps avoid asphalt replacement, which can cost 20 times more than a maintenance procedure. Crack filling also prolongs the life of asphalt and helps prevent water from penetrating into cracks, which is destructive to our city streets (see more info below).
Crack filling is an ongoing maintenance project, but the FY 16/17 prioritization will begin in spring 2017 and continue through the summer.
$125,000 (One-time Measure F funding)
More information about why water is destructive to city streets:
Water is the most destructive element to our city's pavements. If it rained and snowed everywhere but on our roads and bridges, 90 percent of highway and street work would be eliminated. Since that is highly unlikely, we need to prevent water from intruding into our pavements. Filling or sealing pavement cracks to prevent water from entering the base and subbase will extend the pavement life by three to five years. Filling cracks and joints with asphalt materials is not a new maintenance technique. These pavement repair techniques have been commonplace practices for many decades. Asphalt materials are intended to fill the cracks and keep most of the water out of the pavement. When water is kept out, pavement deterioration is slowed - and our city's pavements will last longer and save it will save the city money.
