The project team has taken the following steps during the current COVID-19 pandemic:

  • Maintaining social distancing
  • Avoid sharing tools and sanitizing tools that must be shared
  • Sanitizing common touch points
  • Teleconference whenever possible
    • Single individual as Scribe and attendance taker
  • All digital material submittals
  • Staying home if sick
  • Promote driving separately when possible

FY2021 Pavement Condition Survey

Field work for the FY2021 Pavement Condition Survey is complete. We are currently reviewing the data to select streets for repaving in 2021.

FY2017 Updates

Overview

The Town of Cary is committed to doing what is necessary to efficiently maintain our infrastructure and works to be cost effective by rehabilitating and resurfacing our streets during the early stages of cracking and deterioration. There are approximately 500 miles of town maintained roadway within the town’s limits that are surveyed each year.

Pavement Condition Survey

Every year, a private consultant is employed to perform pavement condition survey work. They conduct a visual survey of the streets maintained by the Town following the methodology and approach in the latest NCDOT Pavement Condition Survey (PCS) Manual as developed by the Institute for Transportation Research and Education (ITRE). The information gathered includes physical characteristics and pavement distress types. This survey is conducted block by block or at break points established by the Town of Cary centerline. The information collected is used to calculate the pavement condition rating (PCR) for each street segment. The data is collected to best determine if streets are candidates for resurfacing, rejuvenating, crack sealing, and/or patching based off the criteria set forth by the Town. Additional items are collected during field data collection which includes, but is not limited to, existing pavement markings, pavement elevations over one inch above gutter, speed humps, curb and gutter in need of repair, tree root damage, and utility conflicts.

A Pavement Condition Survey Report is provided by the engineering consultant with tables and figures to summarize the condition of the street system and the recommended maintenance needs. This report contains all collected pavement data, Pavement Condition Ratings (PCRs), and recommended maintenance activities. The most recent survey conducted concluded that the average rating was 82.7. We use the pavement ratings to get the worst streets in the Town.  Once we identify the worst streets, we capture all the streets that are in the same paving group that are rated 66 or below, Very Poor and Poor categories.   We continue up the ratings and associated paving groups streets until we anticipate our budget will be exhausted.  Paving Groups are areas roughly created based on existing neighborhood boundaries and major thoroughfares.

Construction

Pavement Milling

MillingPavement milling is used to remove one or more layers of asphalt within selected areas of the street. You may see various types of milling operations as the contractor prepares to resurface or patch a street. Edge milling may be used along curb and gutter to provide extra room for the placement of the asphalt along the edge. This is used to prevent the asphalt from extending more than one-inch above the curb & gutter. End joint milling may be used to insure a smooth transition from one street segment to the next. Full width milling may be used to remove distressed asphalt prior to placing new asphalt along a street segment. Pavement milling equipment may even be used to remove layers of asphalt in a small area to be patched. You may experience a bump in the asphalt after the contractor performs milling operations. However, this should be resolved with the forthcoming of the new asphalt surface.

Utility Adjustments

utilityAdjustments to water valve boxes and manholes may be necessary prior to performing the resurfacing operations on a project. These adjustments are normally fairly simply and take only a matter of hours. More complex adjustments can take up to several days to complete. The adjustment can normally be accomplished without interruption of service to the property owners. However, If a situation arises that requires us to temporarily interrupt water or sewer service, we will provide proper notifications to the property owners.

 

Patching

patching Patching may be utilized as a standalone repair or in conjunction with resurfacing or other surface treatments. Patching isolated areas on otherwise healthy streets gives us the opportunity to correct problems before they cause further damage to the street. Patching a small area on a street can eliminate severe cracking or a pothole and bring the street up to a higher standard. Patching is a great way to extend the life of the entire street and reduce the need for costly resurfacing in the near future. Furthermore, patching may be used in conjunction with resurfacing or other surface treatments so that underlying problems do not cause damage and reappear after resurfacing or other surface treatments have been applied.

Curb Replacement

curb

Curb replacement is performed only on curbs that are severely damaged or retain water. These types of curb repairs allows us to prevent water from penetrating underneath the pavement and causing further structural problems.

Paving

PavingStreet repaving or resurfacing provides a new layer of asphalt surface on the street to protect the underlying road structure and improve the quality of the ride. Prior to resurfacing some streets, a tar like tack coat material is applied. This tar like material seeps into the cracks of the underlying pavement, sealing the existing pavement and helps in bonding the new surface course.

 

Rejuvenator

RejuvenatorRejuvenator is a penetrating sealer that simply replaces the vital ingredients that have been lost from the asphalt over time due to exposure to the suns UV rays and wet weather. This application can extend the life expectancy of roads. Extending the life of the roadway helps reduce future costs and tax dollars needed for paving.

When applied on newer pavements, this product helps to protect the asphalt from damage due to exposure to the elements. Everyone understands that we would not buy a new car and never perform an oil change on it. Oil changes are considered part of the preventive maintenance for your car to make it last for many years. Asphalt roads are really not any different. Without timely preventive maintenance, an asphalt road will deteriorate faster than necessary.

The maintenance treatment being provided on your street will help the Town of Cary protect one of its largest assets and give you a road that will provide years of additional service.

The rejuvenator is sprayed onto the asphalt surface and has a pink tint. The pink dye disappears as the rejuvenator penetrates into the pavement. After the rejuvenator has penetrated, a light dusting of sand is applied for added traction. The sand is removed within 48 hours. Material tracked onto concrete areas should weather off in three weeks or so, leaving no stain.

What To Expect

Your cooperation is greatly appreciated and every effort will be made to minimize inconvenience to those adjacent to the work area. Please review the following bullet points that will help in insuring that the construction process moves forward as smooth as possible.

  • During the construction period any work crew member can assist citizens.
  • Citizens will have access to their drive at all times.
  • Please do not park along the street during the designated time period. Vehicles will be towed, if necessary, to complete the work.
  • Please trim any landscaping and keep all debris out of the road/gutter during this time.
  • Drive slowly if you accidentally enter a freshly treated area. (5 mph)
  • For special events, moving, garage sales, etc. call Lane Construction at (919) 876-4550 for assistance.
  • Keep children & pets out of treated areas to avoid tracking into houses.
  • Please refrain from using lawn sprinklers, washing cars, etc. on day of treatment. The pavement must be dry.
  • Rain or unforeseeable conditions may delay work until the following day.
  • Remember, any crew member can assist you during actual construction.
