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 …

Effect Of Multivalent Ions On The Swelling And Mechanical Behavior Of Superabsorbent Polymers (Saps) For Mitigation Of Mortar Autogenous Shrinkage, Qian Zhu

Open Access Theses

The chemical and physical structure-property relationships of model superabsorbent polymer (SAP) hydrogels were characterized with respect to swelling behavior and mechanical properties in different ionic solutions (Na+ , Ca2+ , and Al3+ ). The model hydrogels were composed of poly(sodium acrylate-acrylamide) (PANa-PAM) copolymer with varying concentrations of PANa (0, 17, 33, 67, and 83 wt.%) and covalent crosslinking densities of 1, 1.5, and 2 wt.%. By synthesizing the hydrogels in-house, systems with independently tunable amounts of covalent crosslinking and anionic functional groups were created, allowing for the relative effects of covalent and ionic crosslinking on the properties of the hydrogels …

A Gpr-Gps-Gis-Integrated, Information-Rich And Error-Aware System For Detecting, Locating And Characterizing Underground Utilities, Shaui Li

Open Access Theses

Underground utilities have proliferated throughout the years. The location and dimension of many underground utilities have not always been properly collected and documented, leading to utility conflicts and utility strikes, and thus resulting in property damages, project delays, cost overruns, environment pollutions, injuries and deaths. The underlying reasons are twofold. First, the reliable data regarding the location and dimension of underground utility are missing or incomplete. Existing methods to collect data are not efficient and effective. Second, positional uncertainties are inherent in the measured utility locations. An effective means is not yet available to visualize and communicate the inherent positional …

Since 1988, the UCD Dooge Centre for Water Resources Research has been conducting research in a wide range of water topics including hydraulics, hydrology, coastal dynamics and wastewater with an emphasis on multi-disciplinary collaboration. This paper presents an overview of this research, both past and present, and provides an outlook to the future research directions of the Centre.

Hydro-Environmental Modeling Of Sewage And Riverine Discharges Into A Coastal Area: Comparison Of Depth-Averaged And Three-Dimensional Models, Zeinab Bedri, John O'Sullivan, Aisling Corkery, Louise Deering, Katalin Demeter, Wim Meijer, Gregory O'Hare, Bartholomew Masterson

Conference papers

This study applies and compares two hydrodynamic and water quality models; a depth-averaged (TELEMAC-2D) and a three-dimensional model (TELEMAC-3D) on their performance in simulating the transport and fate of Escherichia coli (a main microbial bathing water quality indicator) in the coastal waters of Bray, Ireland subjected to sewage discharges and freshwater inflows from the River Dargle. The models first calibrated and validated against hydrodynamic and water quality data, were used to simulate Escherichia coli distribution patterns based on mean spring and mean neap tides for dry and wet weather scenarios. The hydrodynamic calibration yielded a good match between both models …
