Bridge, Tunnel and Road Assets
It's difficult to argue against public funds being redirected to areas like homeland security and education, but that does not change the fact that transportation assets are increasingly stressed from age, overuse and benign neglect.

Balvac's services in concrete and masonry repair using vacuum technology can significantly extend the life of transportation assets with little to no impact on the day-to-day use of these structures - and at a fraction of replacement value.

Please visit our project profiles for examples of how this technology has been used to support these vital public assets.

Here are some sobering statistics on the condition of US transportation assets and why the Office of Asset Management under the Federal Highway Administration serves as "an advocate... for maintenance activities" on this crucial part of the nation's infrastructure.

  • Vehicle travel nationally increased by 28% between 1990 and 2000 according to the US Department of Transportation.
  • The Federal Highway Administration forecasts vehicle travel to increase another 50% by 2020.
  • Travel by large commercial trucks increased by 40% over the same time period.
  • For large commercial trucks the increase is estimated to be 90% by 2020.
Bridge deterioration rate studies suggest that concrete bridges, with a typical design life of 50 years, deteriorate slowly over the early part of their lives, followed by medium to rapid decline during the last two decades. Of the bridges in the National Bridge Inventory for 2000, nearly 80,000 concrete structures (excluding culverts) were built between 1952 and 1977. There are more bridges of this material type and age range than any other category, and include the bridges built during the interstate boom of the 1960s. According to Federal Highway Administration data for 2001, just over 83,000 bridges or 14% of the National Bridge Inventory are categorized as structurally deficient i.e., require immediate rehabilitation, to remain open.

The Federal Transit Administration's Tunnel Management System Tunnel Maintenance and Rehabilitation Manual states that 32% of the nation's highway tunnels are between 50 and 100 years old with 4% greater than 100 years old. For rail transit tunnels, approximately 215 miles are greater than 50 years old. For concrete tunnels more than 50 years in age it is highly likely that the concrete was not air-entrained and, therefore, tunnels subjected to temperature gradients may have suffered damage over the years due to freeze-thaw actions.
