Mid-Panel Cracking Of Portland Cement Concrete Pavements In Indiana, Hung-Ming Chen, Yunus Dere, Elisa D. Sotelino, Graham C. Archer

JTRP Technical Reports

Portland cement concrete slabs are a common form of highway pavements in Indiana. As a result of their widespread use, the economic impact of their maintenance and life span is therefore tremendous. In Indiana, these types of pavements have been experiencing premature random transverse mid-panel cracking. This phenomenon has been observed under a variety of environmental and traffic conditions. Also, it has been found that the cracking occurs in conjunction with the opening of the lanes to traffic, within months of construction. In this project, a research synthesis was carried out to determine exactly what the current state of knowledge …

Virtual Weigh Station, John Gregory Green, Andrew P. Nichols, Ed Allen, Luke Nuber, Jose E. Thomaz, Darcy M. Bullock, Guy Boruff, Jay Wasson, Mark Newland

JTRP Technical Reports

Overweight trucks shorten highway life and indirectly increase the costs of maintaining roads. Improved methods for enforcement of commercial vehicle weight laws may increase the number of overweight vehicles caught, thereby prolonging highway life. Improved enforcement may also reduce the number of illegally operating vehicles. This report describes the concept of using existing INDOT Weigh-In-Motion equipment, a laptop computer, and wireless communication equipment, to develop a virtual weigh station screening tool. The Virtual Weigh Station screening tool developed in this project allows officers to read the weights of vehicles crossing WIM scales, in real time, in their patrol cars. Giving …

Worker Exposure To Airborne Contaminates When Using Waste Foundry Sand In The Construction Of Road Embankments, Waseem Afzal, Robert Bertram Jacko

JTRP Technical Reports

A section of road was constructed in Northeastern Indiana in the summer of 1996 using waste foundry sand as the embankment construction material. Initial testing on the waste sand had determined no detrimental health effects. However, it was observed during construction that once the sand had dried, tire-road interaction raised copious clouds of black dust. This led to worker concern regarding airborne silica and silicosis. This study aimed at determining whether the threat of overexposure to airborne crystalline silica existed in regard to Occupation Health and Safety Administration’s (OSHA) Permissible Exposure Limit (PEL). Experiments carried out at the Auburn Foundry …

Wetland Replacement Practices And Procedures For Indiana Highway Projects, James E. Alleman, Steve M. Graves

JTRP Technical Reports

It is estimated that Indiana has already lost more than 80% of its original, native wetlands, and concerns have been expressed that some fraction, and perhaps even a sizable fraction, of these losses can be historically linked to highway construction associated with INDOT-related activities. These wetlands are important for several reasons, in that they help keep ground water and surface water clean, serve as reservoirs for floodwaters, help recharge groundwater, provide habitats for many species of animals, and serve as recreational areas. This underlying concern behind this accusation, therefore, is that the construction of state and federal roads historically carried …

Retributive Justice: Its Social Context, Neil Vidmar

Faculty Scholarship

Until relatively recently, social psychologists have given less attention to retributive justice than to other forms of justice, such as distributive and procedural justice. Although interest in retributive justice is increasing, the fact remains that social psychological research on retribution has tended to ignore, or at least downplay, the insights of sociologists in deference to an approach that examines how individuals respond to deviant acts. Without rejecting psycholgical analyses, this chpater draws attention to the social context and social consequences of retributive justice. Group dynamics are at play in a wide array of settings in which people respond to rule …

Case Studies Of Pre- And Mid-Trial Prejudice In Criminal And Civil Litigation, Neil Vidmar

Faculty Scholarship

This article presents a number of case studies involving pre- and mid-trial prejudice in criminal and civil litigation. The cases reveal deficiencies in the way that prejudicial publicity has been conceptualized and operationalized in many simulation experiments. The studies reveal that potential juror prejudices that concern lawyers and judges involve more than just main effects of mass media. Pre- and mid-trial prejudice also involves more general prejudices, gossip and rumor, the assertion of community normative values about justice, and conformity pressures. Four categories of prejudice recognized in American law are described and labeled: interest, specific, generic and conformity prejudice. The …

Comparing Precaution In The United States And Europe, Jonathan B. Wiener, Michael D. Rogers

Faculty Scholarship

The regulation of health and environmental risks has generated transatlantic controversy concerning precaution and the precautionary principle (PP). Conventional wisdom sees the European Union endorsing the PP and proactively regulating uncertain risks, while the United States opposes the PP and waits for evidence of harm before regulating. Without favouring either approach, this paper critically analyses the conventional depiction of transatlantic divergence. First, it reviews several different versions of the PP and their different implications. Second, it broadens the transatlantic comparison of precaution beyond the typical focus on single-risk examples, such as genetically modified foods. Through case studies, including hormones in …

Thermogravimetric Studies Of Pmma On Silica, Bing Zhang, Frank D. Blum

Chemistry Faculty Research & Creative Works

The thermal degradation of poly(methyl methacrylate) (PMMA) has been studied extensively. It is well accepted that the degradation process is a radical chain reaction involving initiation, depropagation, transfer, and termination reactions. In the degradation process, the factors having observable effects on the decomposition behavior include molecular mass, polydispersity, tacticity, and sample dimensions. The effects of tacticity on the degradation behavior of PMMA were investigated by Kashiwagi et al., Jellinek et al. And Chiamtore et al. The results indicated that both isotactic and syndiotactic PMMA have similar decomposition pathways and activation energies. Isotactic PMMA will decompose at a slightly lower temperature …

Effect Of Polymer-Surface Mobility On Adhesion In Poly(Methyl Methacrylate)-Tape System, Bhavesh C. Gandhi, Frank D. Blum, Lokeswarappa R. Dharani

Chemistry Faculty Research & Creative Works

The interaction between two polymer layers, especially adhesion between them, plays an important role in polymer processing and other applications. Detailed knowledge of the molecular structure and dynamics of polymer interfaces, and how they relate to macroscopic mechanical properties, should help designers construct more functional systems. Unfortunately, there have been few studies where both molecular and macroscopic studies have been performed on similar systems. In previous studies from our group, we have probed the dynamics of poly(methyl acrylate) (PMA) and thermal behavior of poly(methyl methacrylate) (PMMA) on silica. These studies helped us paint a picture for strongly bound molecules on …

Remediation Of Trapped Free-Phase Lnapl, T. M. Whitworth, Andrew Curtis Elmore

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Free-phase light nonaqueous phase liquids (LNAPLs) may be trapped in certain stratigraphic and structural features near or at contaminated sites due to seasonal or other variations in the water table elevation. The purpose of this article is to point out particular subsurface conditions that are conducive to trapping of free-phase LNAPLs and to suggest approaches to remediating LNAPL-contaminated sites exhibiting similar subsurface geometry and stratigraphy. To trap free-phase LNAPL, a structure must have, in addition to closed contours, an upper boundary with pores small enough so that the LNAPL will not enter them. This boundary usually consists of clay-rich sediments. …

Best Available Treatment Technologies Applied To Groundwater Circulation Wells, Andrew Curtis Elmore, Thomas Graff

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Groundwater circulation wells (GCWs) are a quasi-in-situ method for remediating groundwater in areas where remediation techniques that limit the water available for municipal, domestic, industrial, or agricultural purposes are inappropriate. The inherently resource-conservative nature of groundwater circulation wells is also philosophically appealing in today's culture, which is supportive of green technologies. Groundwater circulation wells involve the circulation of groundwater through a dual screen well, with treatment occurring between the screens. The wells are specifically designed so that one well screen draws in groundwater and the second returns the groundwater after it has been treated within the well. Historically, the treatment …
