Rutherford studied failed Midwestern levees, researches potential solutions

Cyclone Engineer Cassandra Rutherford has inspected failed levees along Midwestern rivers. And now she’s working with other engineers to develop technologies that could improve levee performance. Those technologies include using electricity to inspect levees for internal defects and using “biocementation” to strengthen the soil surface of earthen levees.

Clean and green

A number of products you use in your home contain resins. Resins are materials that act as a glue between polymers, and polymers make up synthetic organic materials like plastics and fibers. Chris Williams, a professor in civil engineering, is working on a collaborative project that could replace resins with cleaner, more efficient biomaterials. “It … Continue reading Clean and green

Crews lay high RAP asphalt pavement on a section of road in Crawford County, Iowa. This RAP mixture uses an innovative new rejuvenator.

Iowa State University engineers use innovative rejuvenator to recycle asphalt pavement

Researchers explore greener methods for incorporating high-percentage recycled asphalt pavement mixture into roadways Late last month, a team of Iowa State University (ISU) researchers and industry partners gathered in Crawford County, Iowa, for the unveiling of an exciting development in how engineers use renewable resources in jobsites. Chris Williams is a professor of geotechnical/materials engineering … Continue reading Iowa State University engineers use innovative rejuvenator to recycle asphalt pavement
