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. Airway Drive was completed earlier this month. 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 when the bike lanes are striped. 

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.

Project Update

(Weather Permitting)

Monday, November 19, parking restrictions will be in effect along Yulupa Avenue as crews apply the bike lane markings, weather permitting. Pay close attention to the posted No Parking signs as cars left on the roadway during restricted parking may be towed.

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.
