Public Works Set To Collect Pavement Distress Data On Metro Roads

6/5/2014

Data Collection To Begin This Week

NASHVILLE, TENN. –Nashville and Davidson County residents may see a vehicle like the one pictured below traveling on our roadways starting this week. The high-tech pavement evaluation vehicle will begin winding its way through the streets of Nashville and Davidson County surveying our streets and capturing high quality digital images of pavement surfaces. The data will be used to perform comprehensive analysis of the condition of Metro maintained streets in the eastern ½ of the county.

The technology aboard the vehicle will record the degrees of roughness and distress along street surfaces. Weather permitting; data collection will be complete by early September.

Each year, approximately ½ of Davidson County’s streets are surveyed. The evaluation is a vital component to a continued quality pavement management system. City engineers will use the data collected to manage street maintenance in the most cost effective and efficient manner for the long term streets and roads maintenance.

There are over 5,800 travel lane miles of public roadways and rights-of-way in Nashville and Davidson County. A combination of preventative maintenance techniques from crack sealing, infrared repair, and fog sealing, to full-on asphalt resurfacing when a road surface has reached the end of its service life are used to ensure smooth, safe and economical pavements across our roadway network.
