Permeable pavements could improve safety, benefit environment

In the quest for pavement options that improve road safety and are friendly to the environment, permeable pavements may be an answer, according to findings of a new study.

Researchers led by Professor John Gulliver of the Department of Civil, Environmental, and Geo- Engineering completed a comprehensive review of permeable pavement research and construction in northern climates. The project, funded by the Minnesota Department of Transportation (MnDOT) and the Minnesota Local Road Research Board, revealed that permeable pavement systems offer a number of environmental and safety benefits.

New video highlights how U of M transportation research makes a difference

CTS aired a new video—”How does University of Minnesota research make a difference?”—at our Annual Meeting and Awards Luncheon on April 6. The video highlights research initiatives from 2014-2015, including projects focused on flashing left-turn signals at intersections, “self-healing” pavement, and transit amenities.

New TERRA fact sheet looks at current practices for pothole patching

lowtempcracking2013-4515smJarring potholes can damage vehicles, delay traffic, and frustrate drivers. But that’s not all. Pothole repair is also one of the most expensive pavement maintenance activities. It’s estimated that agencies spend more than $1 billion in the United States each year on pothole and spall repair.

Maximizing knowledge from research and current practices for pavement patching helps agencies make the most of their funding and increase public satisfaction. To advance improvements, the Transportation Research Board recently published a National Cooperative Highway Research Program (NCHRP) Synthesis on Pavement Patching Practices. The synthesis report also is the basis for a new TERRA fact sheet about current practices for pothole patching.

Study sheds light on use of recycled asphalt pavement in cold climates

pavementOld asphalt pavements are increasingly being recycled into new paving projects as a way to save money, materials, and the environment.

In fact, more than 68.3 million tons of reclaimed asphalt pavement, or RAP, and 1.86 million tons of recycled asphalt shingles were put to use during the 2012 construction season in new pavements across the country, saving taxpayers more than $2.2 billion, according to the National Asphalt Pavement Association.

A conversation with the new head of civil engineering


Earlier this year Professor Joe Labuz accepted a five-year appointment as head of the Department of Civil Engineering. Labuz served as interim department head since July 2012 and as a member of the faculty since 1987. He has conducted more than 20 transportation-related research projects in the areas of pavements, soils, and structures and has also served students as the director of both undergraduate and graduate studies. Below he shares his vision and directions for the department.
