Examining The Impact Of Pavement Rehabilitation Trigger Values And Annual Rehabilitation Funding On The Long-Term Network-Level Pavement Condition: A Case Study With The Indiana State Urban Road Network, Menna Noureldin, Jon D. Fricker, Kumares C. Sinha

Purdue Road School

Management of highway assets, including pavements, is immensely challenging in an era of uncertain funding for transportation agencies and higher service expectations from the public. Furthermore, the maintenance of pavement assets in good serviceable condition is one of the most cost-intensive operations for a highway agency.

Between 1996 and 2008, the Indiana DOT spending on improvement of pavement assets fluctuated between 35% and 50% of its asset management budget annually (Everett2012). Therefore, pavement managers are constantly exploring strategies to fulfill their mission of maintaining roads in good condition with the minimumbudget. Strategies may include examining the effectiveness of individual pavement …

Graphical Performance Measures For Practitioners To Triage Split Failure Trouble Calls, Richard S. Freije, Alexander M. Hainen, Amanda L. Stevens, Howell Li, W Benjamin Smith, Hayley Summers, Christopher M. Day, James R. Sturdevant, Darcy M. Bullock

Purdue Road School

Detector occupancy is commonly used to measure traffic signal performance. Despite improvements in controller computational power, there have been relatively few innovations in occupancy-based performance measures or integration with other data. This paper introduces and demonstrates the use of graphical performance measures based on detector occupancy ratios to verify potential split failures and other signal timing shortcomings reported to practitioners by the public. The proposed performance measures combine detector occupancy during the green phase, detector occupancy during the first five seconds of the red phase, and phase termination cause (gap out or force off). These are summarized by time of …

Ada Focused Construction Inspection, Erik Seef, Eryn Fletcher

Purdue Road School

This presentation will introduce inspection guidelines for field staff to implement in inspecting projects with pedestrian facilities, including curb ramps and pedestrian signals. Review of new INDOT curb standards and requirements for accessible pedestrian signals will be included. These recent changes in standards will impact projects and thus it is imperative to advise field staff of what they should be looking for with regard to width and slopes on pedestrian access routes and pedestrian push buttons. Several issues have been noted in the field, including excessive cross slope and running slope, installation of fingertip-actuated push buttons, and substandard level landings …

Post-Failure Capacity Of Built-Up Steel Members, Matthew H. Hebdon

Purdue Road School

Mechanically fastened built-up steel members have long been known to possess internal member redundancy and, as a result, multiple load paths which can be exploited to increase their functional life. Internal redundancy provides the ability to resist total member failure in the event of a fracture of an individual component. However, there is little experimental data in the literature regarding post-fracture capacity in terms of strength and subsequent fatigue life. The experimental study currently underway will provide needed information on parameters that affect the ability of built- up members to arrest a fracture as well as the available remaining fatigue …

Road Safety Audits, Henry Brown

Purdue Road School

A Road Safety Audit (RSA) is a formal review of an existing or proposed road segment or intersection by an independent, multi-disciplinary team. The purpose of an RSA is to identify safety concerns and suggest possible countermeasures to the project owner. There are several benefits to conducting RSAs, including increased awareness of safety and a reduction in the number of crashes. The RSA process includes 8 steps during which the RSA team develops a list of findings and presents them to the project owner for consideration. The RSA process for an existing facility includes a field review during which the …

Drilled Shaft Design & Construction-Integrity Testing Issues, Mir A. Zaheer, David Latka

Post-Fracture Capacity Of Railroad Flat Car Bridges, Teresa L. Washeleski

Purdue Road School

Railroad flatcars (RRFCs) are a convenient option to replace existing deteriorating bridge structures on low-volume roads. They are typically used as the bridge superstructure by placing two or more flatcars side-by-side to achieve the desired bridge width. Utilizing RRFCs as a bridge allows for rapid construction and greater cost savings compared to traditional practices. These benefits make them an attractive solution for rural communities in Indiana, as well as other states.

Uncertainty remains about the response under higher loads than could be easily achieved in the field and the level of redundancy of railroad flatcar bridges. Using RRFCs as bridges …

2014 Road School, Kevin M. Hetrick

Purdue Road School

At the 2014 Road School, this presentation focused on the proposed sliding of the Milton-Madison Bridge, a 15000 ton truss superstructure intended to move laterally 55 feet from a temporary location onto permanent piers. The project was a joint procurement between INDOT and KYTC, with a Design/Build team consisting of Walsh Construction, Buckland and Taylor, and Burgess and Niple performing the slide. The presentation was in early March, with the slide scheduled for later in the month. The slide will be the largest of its kind.

Ada Prowag Status And Common Issues/Solutions, Stephen G. Metzer Aicp, Pws

Purdue Road School

The Proposed Accessibility Guidelines for Pedestrian facilities in the Public Right-of-Way (aka PROWAG), dated July 26, 2011, went through an extensive public comment period that ended in early 2012. The Access Board anticipates issuing final guidance that will be the enforceable standard for facilities in the public ROW. This presentation will provide the latest status of the guidelines and present common problems and creative solutions.

Most Common Errors For Ada Ramp Construction, Stephen G. Metzer Aicp, Pws

Purdue Road School

Curb ramps are essential for persons with disabilities to traverse pedestrian facilities, allowing them to get from street level to the sidewalk. Errors that occur during the construction of curb ramps can result in ramps that are non-compliant with the Americans with Disabilities Act (ADA) guidelines. This presentation will include examples of common sidewalk construction errors and offer ways that project engineers can assess existing ramps to identify cases where additional design assistance may be required.

I-65 South Split Continuously Reinforced Concrete Pavement, Tommy E. Nantung

Purdue Road School

Continuously reinforced concrete pavement (CRCP) is constructed with reinforcing steel placed in along the entire length of the pavement. CRCP forms tight transverse cracks to evenly transfer loads without the need of contraction joints. The result is a continuous, smooth-riding pavement surface capable of accommodating heavy traffic loads in a severe environmental condition. First constructed in Indiana more than 75 years ago on US-50, CRCP became popular with the construction of the Interstate Highway system in the 1960s and 1970s. Many sections of interstate and non-interstate highways constructed at that time are still in service today, having outperformed their original …

Kitchen Table Meetings: Applying The Golden Rule To Property Owner Outreach, David N. Goffinet, David Pluckebaum

Purdue Road School

Property impacts are unavoidable with most road construction. Rather than the owner’s first experience being a drilling rig pull up in their drive-way, the kitchen table meeting process takes a proactive approach to sitting down in the “safety and comfort” of their home, upfront to discuss the type and timing of activities that will occur during design, property acquisition and construction— reducing the “unknown” in this multi-year process that happens too fast for some and too slowly for others. Learn how this approach has not only resulted in increased project acceptance and perception, but also in valuable knowledge that can …
