The City of Campbell maintains approximately 95 miles of roadway. To keep track of the pavement condition of each street and to develop the City’s street maintenance program each year, the City utilizes a Pavement Management Program authorized by Metropolitan Transportation Commission (MTC) called Streetsaver. This program uses data regarding a street’s current pavement condition, maintenance and rehabilitation history, potential rehabilitation treatments, and the City’s budget to provide broad level recommendations for pavement maintenance. Basically, Streetsaver is a computerized system that manages and recommends the proper time to perform the appropriate preventive maintenance work on each street.
Preventive maintenance is the most cost-effective way to maintain the City’s streets. The purpose of preventive maintenance is to extend the service life of a street by preventing water from entering in the roadway, which can cause softening of the underlying street structural section/base and can cause early failure of the roadway surface. If preventive maintenance work is done correctly and in a timely manner, the service life of a street can be greatly extended.
Various types of preventative street maintenance treatments are:
When the condition of a street reaches the point where preventive maintenance no longer is cost-effective, street reconstruction will be required. Reconstruction of a street involves removing the entire roadway structural section and replacing it. The cost can be anywhere from 10 to 100 times more expensive than a typical preventive maintenance treatment. The cost for reconstruction often times is so prohibitive that the annual pavement maintenance funds alone would not be sufficient for such work.
