The cost of maintaining worn-out streets eats up so much of a city's limited funds that often little is left to invest in reconstruction. Yet the only way to reduce the high cost of constant patching and temporary resurfacing is by replacing the worn-out streets. Some cities have found bond issues work to keep maintenance costs low. That's because bond issues allow cities to take advantage of concrete pavement.


Concrete's record of low maintenance and long life before resurfacing fits bond issue financing: The bonds will have retired for many years before any major maintenance is required. State transportation departments that have adopted pavement management systems usually assume a concrete pavement life of 30 to 35 years before resurfacing.
