Neighborhood Street Paving Program

Paving Cycle Process 

A typical road has a life expectancy of 25 to 30 years. Different methods of maintenance and repair are taken throughout a road’s life cycle to make needed repairs. A typical life cycle of a road/street is as follows: 

1. Reclamation 
Pavement reclamation is the process of rebuilding a road by recycling the existing asphalt. The road is broken up and mixed with existing base material. The product is compacted to create a stronger base and three inches of new pavement is placed on the new base. 

2. Shim Overlay 
About 5-10 years later, another inch of asphalt is laid over the existing paved surface. This additional layer strengthens the initial three inches of pavement to extend the life of the road.

3. Crack Sealing
Another 5-10 years later, as the road starts to depreciate, the road may begin to crack. A more cost-effective way to maintain the lifespan of the road is to fill the cracks with hot asphalt to prevent water from filtering through the road and creating further damage.

4. Cold Planing
5-10 years after that, Cold Planing can be done as a process to remove paved areas if necessary. Asphalt milling can remove some or all of the existing pavement to be taken off-site to be recycled for future paving projects. The road is then shimmed with a layer of pavement to fill any ruts that may have developed. Once the shimming has been completed, another 1.5 inches of pavement is added to maintain the strength of the road for the final 10 years of its life cycle.


Neighborhood Street Paving Program

The fiscal year 2016 budget approved by the Mayor and City Council includes an updated Neighborhood Street Paving Program. Since neighborhood streets have a life expectancy of 25 to 30 years, the program is predicated on a 25 year paving cycle. Streets are scheduled based on priority defined by objective measures such as pavement condition and frequent use. 

FY 2005 - 2015 Investments
For the past ten years, Concord has made significant investments in our major arterial roads including: Langley Parkway, Manchester Street, Regional Drive, North State Street, Fisherville Road, Village Street, Clinton Street, Broadway, and Main Street. Investments made on our major roads are shown in red in the graph below. Local streets are depicted in blue. During the Great Recession, it was necessary for the City to reduce expenditures on local streets.

Major and Minor Roadway Investments

FY 2016 - 2017 Investments
Having completed the necessary work on our major roads and with economic conditions improving following the Great Recession, it is now appropriate for the community to reinvest in our local neighborhood streets. 

The current fiscal year 2016 budget includes a bond authorization of $4 million for pavement work of local neighborhood streets during the next two years. 
The recommended capital improvement project for local streets (CIP #78) is based upon future sustainable funding from State Highway Block Grants and a 0.5% tax rate increase through fiscal year 2024. 

The City of Concord values the condition of our roads and our neighborhood streets are the next priority to keep the Concord community safe with improved road quality.

Pavement life is impacted by many factors: traffic volume, vehicle loads (weight), environmental conditions, maintenance, etc. The more a road is maintained, the longer its life cycle will be. The best method for road maintenance is to carry out the paving process through its life cycle with the funding available to get the full value out of the initial investment.
