Pavement Preventative Maintenance 2018
As the weather grows colder, crews are working to complete the striping portion of the Pavement Preventative Maintenance (PPM) project along Yulupa Avenue and Airway Drive. There are several steps involved in the striping process. First, at night crews are measuring and applying the layout as guides for the actual striping. Distances from the curb and lane widths are measured and marked approximately every five feet. These markings serve as guides for the thermoplastic line applications which includes vehicle lane lines, bike lanes (on Yulupa Avenue), crosswalks and directional signs. Street parking will be limited on Yulupa Avenue during the day the bike lanes are striped. Once the lane line striping is in place, crews will apply an adhesive to adhere the reflective and non-reflective buttons to the striping and roadway.
Pay close attention to the dates on the No Parking construction signs along Yulupa Avenue as parking will be restricted when the bike lane striping is applied. No Parking notices will be posted on the construction signs at least 72-hours prior to restricting parking.

Late-October - roadway marking application to both Yulupa Avenue and Airway Drive. No Parking restrictions on during bike lane markings on Yulupa Avenue.
Road work is scheduled to begin at 8:30am.
What is the PPM?
For the PPM, crews first repair arterial streets by removing road markings, applying crack sealing and asphalt dig-outs. An asphalt dig-out is the repair of localized failures in the asphalt, usually in the wheel path, which is accomplished by removing the top three inches of asphalt and replacing with new compacted asphalt. Once the repairs are complete, crews apply slurry seal as a preventative maintenance application which restores the surface of the roadway and extends the overall life of the pavement.
You may have noticed that the PPM Project is similar to the annual Slurry Seal project. Where PPM differs in scope from the annual Slurry Seal is that as the annual Slurry Seal focuses on extending the life of neighborhood streets, PPM focuses on repairing and extending the life of arterial streets.
