Runway 13-31 West Improvements
The Metropolitan Nashville Airport Authority (MNAA) recently worked with Garver to replace the oldest runway pavement at Nashville International Airport (BNA), Runway 13-31 West.
Garver completed survey and geotechnical investigations (via subs) as well as design, bidding and construction phase services. Design services included geometric design, grading, drainage, pavements, markings, electrical, and Navaid improvements.
"We used a rolling dynamic deflectometer to get a broader analysis of the subsurface conditions of the existing runway," said Ryan Sisemore, Aviation Team Director of Garver's East Region. "This non-destructive technology allowed improved placement of our borings during subsurface investigations and yielded better information for us to produce the plans for the reconstruction."
The design team repurposed existing pavement for use as a reclaimed cementtreated base for the new runway shoulders, which made construction more sustainable, saved money, and sped the pace of construction over traditional methods.
"Around 450,000 square feet of existing asphalt runway was repurposed," said Sisemore. "The effect of that goes beyond the material savings. The process lessens the amount of construction traffic on the roads, limiting the interaction of dump trucks with passenger vehicles, which also has an inherent positive impact on the public."
The new runway means BNA now has all concrete runways and meets all FAA runway pavement requirements for gradient and weight loadings. By maintaining runway pavements at the highest service levels, BNA is providing the best conditions for aircraft to operate safely.
