Route 141 Pavement Test Reportedly Bewilders Researchers
According to West News Magazine, researchers are "baffled" by air quality results from an experimental section of Route 141.
According to an article in West News Magazine, researchers with Iowa State University’s National Concrete Pavement Technology Center (NCPTC) are "baffled" by air quality results from the new southbound Route 141.
West News stated that the Route 141 pavement experiment added $130,000 to the cost of the project and is believed to be the first U.S. location for testing such a smog-alleviating concept.

Now, researchers are trying to determine what caused such a drastic change in results. In the article, researchers said they found a thin layer of calcium carbonate in the test area which is a surprise since that has not been a problem in Europe where titanium dioxide has been used on roads for years.
Researchers are working with the Missouri Department of Transportation as they continue to investigate the issue and monitor the experiment, according to West News.
