Epoxy Asphalt Placed on the San Francisco-Oakland Self-Anchored Suspension (SAS) Bay Bridge
The newest suspension bridge in the United States will open shortly using Epoxy Asphalt as its long life pavement.
Redwood City (I-Newswire) August 1, 2013 - Earlier this month, ChemCo Systems supplied Epoxy Asphalt to support the paving of the new East Span of the San Francisco-Oakland Bay Bridge in California. The $6.4 billion bridge is scheduled to open to traffic later this year and immediately handle a daily average traffic volume of 280,000 vehicles. The traffic count will establish the new bridge as the busiest in the world (for 10 lanes). The unique Self Anchored Design utilizes a single tower and represents the largest of its type in the world.
The new bridge replaces a 1930's era steel truss bridge (East Span) which is unable to meet current seismic performance requirements. The existing bridge uses an earlier generation of Epoxy Asphalt in a ¾" overlay that has lasted 37 years and approximately 3 billion vehicle crossings.
The current project features 4,400 metric tons (4900 U.S. tons) of Epoxy Asphalt installed on the 16,680 m2 (180,120 ft2) steel deck in two 1 inch thick layers. The paving project took less than 2 weeks to complete and includes 10 lanes and 4 shoulders.
Epoxy Asphalt is specially designed for long span bridges which use orthotropic steel decks to minimize weight. The unique combination of epoxy and asphalt provides a highly durable road surface that handles high traffic loads with a long operating life and outstanding fatigue performance. The new San Francisco Bay Bridge has a design life of 150 years and the epoxy asphalt pavement is projected to last 25 to 40 years, much longer than alternative driving surfaces.
ChemCo Systems manufactures Epoxy Asphalt in California. It is frequently exported for use on long span bridges internationally, especially in China.
