The Village owns and maintains approximately 167 miles of streets. The State of Illinois and DuPage County maintain bigger arterial roads like Ogden Avenue and 63rd Street.
The Village evaluates streets annually to ensure they remain safe and driveable. The evaluation process consists of quality controls including inspections, a pavement rating system and high maintenance standards. All streets generally fall into two categories:
Maintainable: A street that is crack filled, patched and resurfaced on a regular schedule, allowing it to continue to function.
Above: Good Drivability / Low Ownership Costs
In Need of Reconstruction: The pavement has failed and is not salvageable. Reconstruction is the most expensive and disruptive type of pavement project, costing four times as much as regular maintenance.
Above: Costly Reconstruction Needed
Based on the 2010 pavement assessment, the Village issued $25 million in bonds to finance reconstruction projects and used existing funding for increased maintenance activities. In 2015, the Village will finish the construction projects and approximately 99% of all streets will be in Maintainable condition.
Since 2011, the Village has reconstructed 12 miles of streets in 11 neighborhoods (including projects currently underway), resurfaced 43 miles of streets, and completed regular crackfilling and patching on the remainder of streets.

The Village maintains streets at the most cost effective level. To reduce project costs and minize inconvenience to residents and businesses every effort is made to coordinate the timing of street projects with other infrastructure projects.
It costs the Village roughly $0.5 Million per mile to resurface and perform regular maintenance on a street. However, if a street falls into disrepair due to a lack of maintenance, it costs $2 million per mile to reconstruct it from the dirt on up. The key to cost-effectiveness is to perform maintenance activities at critical points and keep them in driveable condition, before they need to be reconstructed just a few years later, at 4x the cost, as shown in the graph below.
With regular maintenance, asphalt streets can last decades in good driveable condition.
Each pavement surface has a unique structure, and is subjected to unique environmental conditions. What lies below the asphalt surface can vary greatly from block to block. Flat or steeply sloped pavement, good or bad drainage, and the amount of tree canopy can make a big difference in the speed with which pavement deteriorates.
There are three primary types of maintenance activities performed after a street is reconstructed: crack filling, patching, and resurfacing. This routine maintenance reduces repairs and prolongs pavement life.
Wear and tear from the weather and traffic breaks down asphalt over time. Within three years after a street is paved, cracks are filled with a rubberized asphalt compound to prevent water from infiltrating the pavement. This process is generally repeated every few years, until it is no longer effective.
As the pavement ages, it is not uncommon for potholes to develop which impact ride quality. Where and when this occurs, the Village will fill potholes with asphalt, or if warranted, patch the surface of the road as a "stop gap" measure until it is resurfaced again. Patching generally takes place within 10 to 20 years after the street is constructed.
Every 17 to 20 years or so, the Village resurfaces each asphalt street. Here's what a street looks like after years of maintenance that's ready for resurfacing:
Resurfacing typically involves the removal of the asphalt surface, full depth base patching where needed, and the placement of a new asphalt surface. The rountine cycle of crack filling, patching and resurfacing is then repreated over the life of the pavement.
The photos below depict what a resurfacing project will look like, both during, and following completion.
