One-third of the nation’s major urban roadways – highways and major streets that are the main routes for commuters and commerce – are in poor condition. These critical links in the nation’s transportation system carry 70 percent of the approximately 3.2 trillion miles driven annually in America.

Monday, March 7th, 2011We can engineer the pavement material to have porosity. We can engineer voids into the material so that instead of 4% air voids, we can have up to 20% air voids that allow water to penetrate through the pavement surface.
With the porous pavement option, we have water flowing through the surface of the pavement and into the stone where we can store the water. Then it will eventually infiltrate into the natural sub-grade that we have underneath.

Dear Friends,
It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.
Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.
We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.
We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
