Making Quieter Highways

An anonymous reader writes "Researchers at Purdue are investigating ways to make life for those who live near major highways more quiet. They have found that most of the noise is literally where the rubber hits the road, not engine noise or even passing winds. The team has come up with a new form of pavement that is in testing in Arizona and will soon be installed in California. The pavement is simply asphalt with some mixed in rubber."

A similar compound was invented in the Netherlands ages ago, using concrete (cheaper and easier to handle then rubber). It is called ZOAB ("Zeer Open Asfalt Beton", meaning "Very Open Asphalt Concrete") This highly porous material has several beneficial properties, such as being more quiet, and more efficient in draining water, thus preventing aquaplaning. It is a safer road, alltogether. Now some university is passing this off as a "Great American Invention"?!?!

Hmmm, yes -1 eurotrash.

You see you they are using asphalt, not concrete. They are using a different method. But, in your blind anti-Americanism you have to speak up and say that you have found offense where none was intended or given.

I wish these people would just combine their efforts instead of staying in that NIH (Not Invented Here) mode.

Americans can be stubborn. I guess that's why men in South Carolina still have sex with pigs and goats, because new ideas about women came from North Carolina. Please don't ask me where babies come from in South Carolina, because I just don't know...nor do I want to know.
