WSDOT Earns A 2016 Perpetual Pavement Award for SR 512

WSDOT Earns A 2016 Perpetual Pavement Award for SR 512

MEDIA RELEASE:  June 21, 2017

For Immediate Release

WASHINGTON STATE DEPT. OF TRANSPORTATION WINS 2016 PERPETUAL PAVEMENT AWARD
WSDOT Honored for Success of Long-Life Asphalt Section of State Route 512

The Washington State Department of Transportation (WSDOT) was awarded a 2016 Perpetual Pavement Award by the Asphalt Pavement Alliance (APA) for a 5.01-mile section of State Route 512 in Pierce County that runs from Portland Avenue to the intersection with SR 161. This is the third Perpetual Pavement Award earned by WSDOT.

To qualify for this prestigious award, a pavement must be at least 35 years old and never suffered a structural failure. The average interval between resurfacing of each winning pavement must be no less than 13 years. The pavement must demonstrate the characteristics expected from long-life, Perpetual Pavement design: excellence in design, quality in construction and value to taxpayers.

Engineers at the National Center for Asphalt Technology (NCAT) at Auburn University in Auburn, Alabama, evaluated the nominations and validated the results for the Perpetual Pavement Award winners.

WSDOT built the first section of the road (MP 3.61 to MP 5.69) in 1970 with a 4.8-inch gravel base followed by 2.4 inches of crushed stone and 9 inches of hot mix asphalt (HMA). The road was crack-sealed in 1989 before being overlaid with a 0.72-inch HMA binder course and a final 1.8-inch HMA surface course. In 1998, crews filled ruts in the pavement with a leveling course before placing a 1.8-inch Superpave asphalt overlay. The only other work done on this section has been preventive maintenance.

The second section of SR 512, from MP 5.69 to MP 8.62, was built in 1972. WSDOT originally constructed a 14.4-inch pavement, consisting of a 3.6-inch gravel base followed by 3.6 inches of crushed stone and a 7.2-inch asphalt pavement mix surface. WSDOT placed a 1.8-inch HMA overlay in 1994, and in 2013 milled 1.8 inches from the outside truck lanes before laying a course of Superpave asphalt pavement mixture. Since that time, there has been only minor preventive maintenance.

“We are very pleased to receive this national recognition of the high-quality work completed on SR 512,” said John Wynands WSDOT region administrator. “This project is just one example of pavement maintenance and preservation work occurring statewide as we focus on keeping our assets in a state of good repair. WSDOT has a long history of focusing on solid design and construction principles to extend the useful life of our pavements, and the increasing demand on our resources makes those smart decisions even more important.”

As a winner of a 2016 Perpetual Award, WSDOT will receive an engraved crystal obelisk, and its name and project will be added to a plaque on permanent display at the NCAT Research Center at Auburn University.

“One of the keys to sustainability is long life,” said Amy Miller, P.E., national director of the Asphalt Pavement Alliance. “Asphalt roads can be engineered to last indefinitely with only routine maintenance and periodic surface renewal.”

“The advantages of these Perpetual Pavements are significant. Life-cycle costs are lower because deep pavement repairs and reconstruction are avoided. User delays are reduced because minor surface rehabilitation requires shorter work windows and can avoid peak traffic hours. And there are environment benefits because minimal rehabilitation, combined with recycling any materials that are removed from the pavement surface, reduces the amount of material resources required over the pavement’s life.”

The Asphalt Pavement Alliance (www.driveasphalt.org) is a partnership of the Asphalt Institute (AI), National Asphalt Pavement Association (NAPA) and the State Asphalt Pavement Associations. The Asphalt Pavement Alliance’s mission is to establish asphalt as the preferred choice for quality, performance and the environment.

The Asphalt Institute (www.asphaltinstitute.org) is the international trade association of petroleum asphalt producers, manufacturers and affiliated businesses. AI promotes the use, benefits and quality performance of petroleum asphalt, through engineering, research, marketing and educational activities.

The National Asphalt Pavement Association (www.asphaltpavement.org) represents the interests of U.S. asphalt producers/contractors before Congress, federal agencies, and other national trade and business organizations. NAPA supports an active research program designed to improve the quality of asphalt pavements and paving techniques used in the construction of roads, streets, highways, parking lots, airports, and environmental and recreational facilities.

The State Asphalt Pavement Associations (www.asphaltpavement.org/sapas) represent the interests of asphalt pavement producers and paving companies at the state and local level across the United States.

2017 – 2019 State Transportation Budget

Report from Tom Gaetz – WAPA Senior Advisor – 5.12.2017

 Washington State – 2017-19 Transportation Budget 

This week, Washington State House and Senate leaders finally reached an agreement and passed the 2017-19 Transportation budget. I’ve provided links to the official docs below. In summary, the new budget:

  • Appropriates about $8.5 billion over the next two years.
  • Spends $4.2 billion in the various capital programs.
  • Shifts $60 million of additional TPA funds to help fill the $149 million cost overrun on the Alaska Way Viaduct Deep Bore Tunnel project.
  • Maintains the Connecting Washington package and only makes minor modifications by advancing some funding on five projects to earlier years.
  • Adds $162 million to existing fish passage barrier funding. The planned spending for these projects averages about $90 million per biennium through 2033, still far short of the $2.4 billion estimated total need.
  • Funds several studies, including:  Board of Pilotage, I-405 Toll Data, Air Cargo, Role of the WTC, and alignment of an Ultra High Speed Rail line between Vancouver BC and Portland OR.
  • The VW settlement language has a minor reference (Sec 702), but transportations leaders decided to move the bulk of the framework to the Capital Budget, which has not been adopted as of this writing.
