Pavement Lasts 120 Years - New Recipe
Skepticism Mixes with Enthusiasm Over 120-year Concrete Recipe
by Sean Ryan, The Daily Reporter (Milwaukee, WI), 06.21.2010
Road builders question the practicality of concrete that could last 120 years and significantly cut the industry's workload.
Materials researchers have found ways to extend pavement life to more than a century. Konstantin Sobolev, a University of Wisconsin-Milwaukee associate professor, is trying to build on that success and to further improve concrete's ability to withstand water damage.

Water that seeps into pavement carries minerals and chemicals that can damage the pavement. Water that soaks into concrete also freezes and expands, causing the pavement to crack.
Sobolev's work involves adding different chemicals to concrete that will change the material on a molecular level when the pavement sets. By doing this he can, for example, create a spiky surface that, although microscopic, prevents water from soaking into the pavement.
Using different materials and making sure pavement sets under optimal moisture levels and temperatures in the field can increase costs on the front end but can create a longer-lasting road, Sobolev said........read more
