Peak Pavement Management System

The town contracts with a private firm every three years to obtain a pavement condition survey (most recently in Fall 2023) determining which streets need to be resurfaced, and what amount of work is required. From that report, a number of neighborhoods are selected for pavement preservation and/or asphalt resurfacing each year.

Where can I find information on the condition of my street?

Use the new Peak Pavement Management System Tool that shows Pavement Condition Index (PCI) scores for every street on the Town street system. This map also highlights streets included in our annual resurfacing projects.  

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 methods are used to improve street conditions?

See information below about the variety of methods used to improve and / or maintain town streets. The method used on a particular street depends on the condition of the existing asphalt. 

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.

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 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 
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.

Chip Seal 
A surface treatment consisting of a layer of asphalt binder with embedded aggregate.  Chip seals provide a skid resistanturface, seals cracks, and protects against further deterioration of the pavement. Chip seals are low cost and generally used on streets in fair to good condition and can extend pavement life by 5-7 years.  Chip seals can also be combined with crack seals and/or followed by a slurry seal or microsurfacing.

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.
