The lab, in the Institute for Transportation&#8217;s <a href=\"http:\/\/www.intrans.iastate.edu\/asphalt\/\">Asphalt Materials and Pavements Program<\/a> at Iowa State, developed the asphalt substitute, which will be part of a demonstration project in Des Moines, Iowa&#8217;s capital.<\/p>\n<p>The lab is headed by Christopher Williams, associate professor of civil engineering, who adapted a thermochemical process called fast pyrolysis, which quickly heats farm and lumber wastes or other types of biomass without oxygen. The process produces a liquid bio-oil that can be used to manufacture fuels, chemicals, and asphalt, plus other environmentally friendly products. Three recent Iowa State grad students started a company, <a href=\"http:\/\/www.avellobioenergy.com\/\">Avello Bioenergy Inc.<\/a>, that licensed the technology to develop and market products made from fast pyrolysis. Those products include <a href=\"http:\/\/www.avellobioenergy.com\/index.cfm?nodeID=22287&amp;audienceID=1\">Bioasphalt<\/a>, derived from the work in Williams&#8217;s lab.<\/p>\n<p>Bioasphalt will get a real-world test, thanks to the city of Des Moines that is using the material to pave part of the 10-foot wide Waveland Bicycle Trail on the city&#8217;s northwest side. The first test uses a 5 percent mix of bioasphalt. Williams says a successful demonstration would lead to more pavement tests containing higher percentages.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A lab at Iowa State University in Ames has developed a potential green replacement for asphalt derived from petroleum, which will be put to a test in Iowa&#8217;s sometimes extreme winters and summers.
