Last week, Purdue Lyles School of Civil Engineering students and faculty members had the opportunity to participate in an interactive field trip as part of the INDOT EVOLVE mentoring program. The field trip took place at the ongoing INDOT I-69 Interstate construction project near Bloomington, Indiana. Some of the onsite tour stops included crossing locations, Plummer Creek II Mitigation Site, and the SR45 and SR37 Interchanges.

Here is a quick look at the anticipated delivery of a 1937 truss bridge originating from Michigan. The trusses will be setup later this spring for use at Purdue University's Steel Bridge Research, Inspection, Training, and Engineering Center (S-BRITE) located outside of campus. The S-BRITE Center is under the direction of Associate Professor of Civil Engineering Robert Connor.

U.S. infrastructure continues to decay at an alarming rate, as exemplified by the low grades consistently awarded by the ASCE Infrastructure Report Card. While there are many contributors to the decay and degradation of our nation's transportation infrastructure, one that cannot be overlooked in many states is the annual winter application of deicing salts.

On March 6, 2015, Good Morning America aired an investigation on bridge accidents. Footage was used that originated from Purdue University Associate Professor of Lyles School of Civil Engineering Robert Connor and his research with a web-based bridge monitoring interface. His research focused on a short-term monitoring solution for a more effective asset management tool used by bridge owners when inspecting critical onsite locations.

Runway incursions are a significant safety concern, particularly at general aviation airports. In 2013, there were over 1200 runway incursions. In May 2014, the Federal Aviation Administration (FAA) awarded a project to Profs. Darcy Bullock and Sarah Hubbard to evaluate the feasibility of using rumble strips on taxiways to warn pilots of the upcoming runway with the objective of reducing runway incursions.

Purdue University researchers have produced a new site investigation torque tool, known as SPT-T that can better characterize the soil and provide valuable data on shear strength, particularly for clay soils and glacial till. It replaces the standard practice in such soils of recovering low-quality samples that are then tested in unconfined compression. Obtaining additional real-time data onsite at a lower cost and increased reliability will lead to more effective and economical design of geotechnical structures in these soils.

An integral component of JTRP is providing electronic access to technical reports for INDOT, as well as colleagues around the world. In 2010, JTRP and the Purdue Libraries began digitizing technical reports dating to the 1950s. More than 1,500 technical reports now reside in the JTRP Technical Report Repository on e-Pubs with 787,695 total downloads as of April 17, 2014.

A JTRP study (SPR-3709) led by Purdue Civil Engineering Professors Phillip Dunston and Hubo Cai has been initiated to analyze the data from the IC rollers. This data, along with the corresponding Dynamic Cone Penetrometer (DCP) acceptance tests, will be used to develop allowable tolerances and acceptance testing criteria.

The objective of this research is to develop design strategies to improve the efficiency and optimize the design of the Indiana modified U-beam. The research program has been focused in three areas (1) evaluating the live load distribution appropriate for the design of U-beams, (2) assessing the behavior and design of the bridge deck when supported by U-beams, and (3) evaluating both the shear strength and shear design of the composite U-beam system.
