National Cooperative Highway Research Program at 50 Years: Anniversary Video
National Cooperative Highway Research Program (NCHRP):
This video highlights the accomplishments of the National Cooperative Highway Research Program’s (NCHRP’s) 50 years of collaborative research, which has contributed results and innovation vital to the state departments of transportation and the nation.
Administered by the Transportation Research Board and sponsored by the member departments of the American Association of State Highway and Transportation Officials, in cooperation with the Federal Highway Administration, NCHRP was created in 1962 as a means to conduct problem-solving research on issues faced by the state transportation agencies in building, managing, maintaining, and evolving the nation’s highway system.

One Design—10,000 Bridges Video
Strategic Highway Research Program (SHRP 2):
TRB’s second Strategic Highway Research Program (SHRP 2) has released a video that describes a new tool kit for designing and constructing bridges that is intended to help local contractors use typical equipment to build bridges quickly and efficiently.
The tool kit was demonstrated in construction of a bridge over the Keg Creek near Council Bluffs, Iowa. The design reduced the road closure to only two weeks from a more typical six months. Time-lapse photos at the end of the video show the construction.

Protecting Surface Waters with Inlet Protection Devices
Florida Department of Transportation:
Researchers at the Stormwater Management Academy, University of Central Florida, recently tested seven curb and six drop inlet protection devices currently used in Florida during construction activities to determine their effectiveness in reducing sediment and other pollutants from entering the storm drainage system. Stormwater discharge is regulated by the National Pollutant Discharge Elimination System (NPDES). An effective IPD should let water flow through the device while capturing solids. Researchers found that both curb and drop IPDs tested reduced the amount of sediment and nutrient runoff but to different degrees and with unique removal rates. The results of these studies will be used to update the State of Florida’s Sediment and Erosion Control Manual and to develop a training course on sediment control.

Insitu Pipe Inspection and Repair
Florida Department of Transportation:
FDOT constructs, manages and maintains much of the pipe infrastructure system in Florida. Pipes are expected to perform for many years, but repairs can be difficult, disruptive, and expensive. University of Florida researchers recently studied a range of pipe repair methods that were most successful at enhancing the long-term durability of pipe and the pipe network. They added the methods to a pipe repair matrix, a compilation of repair methods and data covering the past 15 years for metal, HDPE, PVC and concrete pipe . Engineers, FDOT personnel, and contractors can use the matrix as guidance to select the best insitu repair method for the situation.

Cone Trucks
Louisiana Department of Transportation and Development:
Conventional site investigation with soil borings and laboratory testing is expensive and time consuming, and often the procedures require highly skilled and experienced technicians. The cone penetrometer test (CPT) is a robust, simple, and economical test that can provide continuous soundings of subsurface soil with depth. The CPT can provide rapid, accurate and reliable results in assessing the engineering properties of soil. This video describes the implementation of CPT technology as a cost effective alternative to conventional soil exploration operations within LADOTD.

Crumb Rubber
Louisiana Department of Transportation and Development:
Researchers at LADOTD and LTRC are transforming recycled scrap tires into smoother, quieter, and longer-lasting roads and highways by utilizing crumb rubber, made from finely graded shredded tires, to construct some of Louisiana’s newest roads. In this video, you will see how this material is made and applied to Louisiana asphalt mixes. You will also learn how Louisiana saves approximately $7500 for every mile of construction by utilizing crumb rubber. Crumb rubber mixtures has allowed LADOTD to save dollars without compromising quality and performance of our asphalt roadway pavements.

Repair of Existing Roadway Embankments with Non-woven Fabric Reinforcement
Louisiana Department of Transportation and Development:
While current embankment specifications are more restrictive, many aging embankments in Louisiana constructed with heavy clay soils are experiencing repetitive slope failures. This led LADOTD highway maintenance engineers to seek a cost-effective way to permanently repair these slopes. Using non-woven geotextiles as reinforcement layers, the tension forces mobilized in the geotextile enhances the overall stability of a slope, creating embankments that perform better under typical Louisiana conditions. This video demonstrates how state DOT maintenance forces can utilize an inexpensive geotextile to resolve the reoccurring slope failures attributed to high PI soils with minimal allocation of equipment and personnel.

I-35E Maryland Avenue Bridge
Minnesota Department of Transportation:
The 1,300-ton bridge, built alongside I-35E, was moved into place using new construction technology. The Minnesota Department of Transportation used a giant automated machine called a Self-Propelled Modular Transporter (SPMT) to move a finished bridge into position. A first for MnDOT, the move took place Aug. 18, 2012 over I-35E in St. Paul at the Maryland Ave. Bridge site.

SMART Signal Research
University of Minnesota:
Researchers at the University of Minnesota are working to improve that timing and ease congestion. Civil engineering professor Henry Liu developed the SMART Signal system, a cost-effective way to monitor traffic signal performance that represents a quantum leap in traffic signal operations. The SMART Signal system is installed in a traffic controller cabinet and sends information about traffic performance to the traffic control center, such as where and when congestion patterns are emerging.
