Smart Work Zone Activity App (SWiZAPP) makes work zones work
With the increase in the computing power of portable electronic devices such as smartphones, smart work-zone information can be exchanged simply and cost-effectively.
|
|
But that’s only one reason why Dr. Yaw Adu-Gyamfi, an assistant professor from the University of Missouri-Columbia, spearheaded a research project aimed to design, develop, and deploy a cross-platform mobile application for collecting and reporting real-time work-zone activity information. More

Snowplow route optimization offers big potential
The Iowa Department of Transportation (DOT) alone is responsible for servicing 24,000 lane miles of roadways during winter road maintenance operations. Optimizing the current routes used by snowplows has the potential to result in significant cost savings, improved safety and mobility, and reduced environmental and societal impacts.
|
|
A recent research project at the Institute for Transportation (InTrans) looked at operations for the Iowa DOT’s District 3, located in northwest Iowa, which services about 4,000 lane miles from 20 depots, to solve two optimization problems that could ultimately expand to other districts and local agencies.

New spreadsheet tool helps determine optimum time for equipment replacement
|
|
A new spreadsheet tool will help local agencies plan for their equipment needs with more certainty. The Equipment Life-Cycle Cost Analysis Tool (E-L-T) allows users to assess the optimum time to replace their trucks and motor graders considering both purchasing and leasing options.
|
|
|
“We know that counties spend about half their budgets on maintenance, and equipment is about 27 percent of maintenance at any given time,” said Jennifer Shane, a principal investigator on the project that developed the tool. “We wanted to develop something county engineers can tailor to their needs and use to present to their boards on their equipment needs.” More

CP Tech Center releases Guide to Lightweight Cellular Concrete for Geotechnical Applications
|
|
Long used as a construction product for flooring systems, lightweight cellular concrete (LCC)— a mixture of portland cement and water slurry, combined with preformed foam to create air voids—has continued to expand its applications into a variety of fields, including the geotechnical industry.
|
|
|
In order to provide information for construction professionals and design engineers on the use of LCC in specifically geotechnical applications, the National Concrete Pavement Technology Center (CP Tech Center) in collaboration with the Portland Cement Association (PCA) released the Guide to Lightweight Cellular Concrete for Geotechnical Applications.
