Metro Public Works to Begin Paving Throughout Nashville and Davidson County Next Week


Paving Season 2015 Gets Started

NASHVILLE, Tenn. – During the past several weeks, work efforts have been focused on pothole filling and repairing streets and street surfaces that were compromised during the winter weather Nashville experienced this year. While pavement repair continues year round, the emphasis now turns to paving Nashville's roads.

Starting Monday, March 30, Public Works will begin paving streets throughout Nashville and Davidson County. Paving, pavement repair and pavement preservation methods including fog-seal, crack sealing and infrared repair, are planned for streets throughout the county.

One lane remains open to traffic during milling and paving operations, but motorists should be advised that there may be some delays or driving pattern shifts. Asphalt resurfacing takes place in the following steps that typically take about 3-4 weeks to complete pending weather and site-specific conditions:

  1. Adjustment (lowering) of utilities to allow milling machines to navigate the roadway
  2. Removal (milling) of existing roadway surface using a milling machine
  3. Readjustment (raising) of utilities so that they will again be flush with the new surface that will be applied
  4. Application of a tack coat to milled surface to serve as a binder for the new surface that will be applied
  5. Paving application
  6. Paint crosswalks, center lines, bike lanes, and other pavement markings on new surface

“Nearly every trip, whether by walking, driving, biking or public transit – begins and ends on our public roadways. Taking good care of our streets is critically important to the safety and mobility of the traveling public, and plays an essential role in our quality of life,” Mark Macy, Public Works Assistant Director of Engineering, said. “We are especially thankful that we are able to meet the call to pave more roads and invest in our infrastructure.”

Metro Public Works' paving program strives for 12 years of pavement life expectancy on roadways. With a new infrared truck going into operation this summer, permanent pavement repairs will be able to be made which can extend the life of roads an additional 2-3 years. The specialized truck uses infrared technology to heat the asphalt around potholes prior to filling them, thus delivering a stronger bond to the surrounding road and preventing repeated repairs. “Through a variety of pavement preservation techniques and best practices in pavement management strategies, we continue to utilize the most effective solutions available to maintaining our roadways,” Don Reid, Paving and Right-Of-Way Manager said. “With our ability to more broadly use infrared technology, we're excited to be making more and lasting improvements.”

Metro Public Works uses a combination of preventative maintenance techniques to prolong the service life of roads year round. These include Crack Sealing which repairs cracks in the roadway and prevents further asphalt deterioration, Infrared Repair, Fog Seal, and EZ Street which is a mixture custom made for this climate.

Paving season coincides with the opening of asphalt plants which typically occurs early spring in the Middle Tennessee region. Temperatures of approximately 45 degrees and above are essential to optimum resurfacing.

This year's capital budget includes $19 million dollars for paving.

The Public Works Department is responsible for maintaining over 5,800 road lane pavement miles made up of approximately 22,000 segments throughout Nashville and Davidson County. Over 140 lane mile are expected to receive paving this year.
