Pavement Management System



The Town currently maintains over 20 miles of streets on the Town's transportation system, and performs a Pavement Condition Survey every two to three years to prioritize future street resurfacing contracts. The pavement condition survey was completed in summer 2023. The Town utilizes PAVER pavement management system to analyze the pavement condition to plan and prioritize street repairs.


Frequently Asked Questions

How does the Town determine which streets to perform preservation maintenance and resurfacing?

Starting in 2023 the town will complete a pavement condition survey every three years to determine the Pavement Condition Index for each street. Utilizing the PAVER analysis and staff report repair projects will be selected.

How long does asphalt pavement typically last?

The lifespan of asphalt pavement depends on a number of factors, including topography, drainage, material/construction deficiencies, utility work, expansion/contraction, traffic volume, heavy braking/turning movements, chemicals/petroleum spills, and neglect of prior preservation/maintenance. Properly maintained asphalt pavement should typically last between 20 and 30 years, or 25 years on average.

What tools does the Town use for pavement maintenance?

The town uses a wide variety of preservation methods and asphalt resurfacing in residential neighborhoods each year.  

Crack Sealing - seals minor cracks to prevent water penetration into the underlying asphalt, stone, and soils. Crack sealing is generally used on streets 0-5 years old that are in relatively good condition with low distress and/or narrow crack widths.  Crack sealing is a low cost preservation treatment that extends pavement life by 3-5 years and can be done in conjunction with other treatments such as slurry seals, chip seals, and microsurfacing.

Asphalt Leveling – A small paving machine is used to level ruts, depressions, sags, and sunken utility cuts.  As the paving crew is moving through an area they can also fill potholes. This maintenance procedure will provide needed repairs, improve ride quality, and show the Town is aggressively repairing streets.  This can have a positive impact on the PCI as it changes the distress pattern to light patching.  Note: if major cracking is evident this may require full depth base repair prior to leveling.  This type of work repairs current conditions and preps the street for future resurfacing.    

Asphalt Rejuvenation - a chemical applied that penetrates the asphalt well below the surface and revitalizes and restores components of the asphalt lost during production and the natural aging process. Asphalt rejuvenation is a low cost treatment generally used on streets that are in good condition with low distress and can extend pavement life by 2-4 years.

Slurry Seal - is a surface treatment consisting of a carefully designed mixture of asphalt emulsion, fine aggregate, and water/additives that adheres firmly to the pavement and provides both an extended life and a skid-resistant texture.  Slurry seals are low cost preservation treatments generally used on streets in good condition that can extend pavement life by 5-7 years.  Slurry seals can also be done following crack seal or chip seal applications.

Microsurfacing - a thin (1/4 inch) asphalt emulsion blended with finely crushed stone for traction, applied over the existing asphalt surface that preserves and protects the underlying pavement structure and provides a new driving surface. Microsurfacing is generally used on streets that are in fair condition and have low to moderate distress and narrow crack widths.  Microsurfacing can extend pavement life by 6-8 years.

Asphalt Patching - removal and replacement of small areas of pavement when the remainder of the street is in relatively good condition.  Patching is moderately higher cost and is generally used to address localized pavement damage due to underlying soil settlement and/or in conjunction with underground utility repairs that cannot be addressed by other pavement preservation techniques.  

Asphalt Resurfacing - includes complete removal of the top layer of asphalt, asphalt patching of the worst areas of structural damage, and repaving a new top layer of asphalt surface. Asphalt resurfacing is a high cost replacement of the asphalt surface and is generally used on streets that are in fair to poor condition and have moderate to heavy distress, alligator cracking, and/or large crack widths.
