Flexible Pavement Drainage Monitoring, Performance, And Stability, Aiwen Feng, Jianfeng Hua, Thomas D. White

JTRP Technical Reports

The current study is a continuation of the study FHWA/IN/JTRP project HPR-2078, “Locating the Drainage Layer for Flexible Pavements”. In this previous study, three test sections were constructed in a new pavement on a by-pass around Fort Wayne, Indiana. These test sections were instrumental to record temperatures, moisture, frost penetration, rainfall and subdrainage system overflow. Collected data and Finite Element Method (FEM) analysis indicate the subdrainage systems are performing satisfactorily. However, concern developed over the stability and rutting characteristics of the open-graded drainage layers. As a continuation study, longer term environmental and subdrainage performance data was collected. Additional data was …

Landslide Remediation Using Unconventional Methods, Richard J. Deschamps, Cary B. Lange

JTRP Technical Reports

Landslides are very common within the residual soils and sedimentary rock of Southern Indiana. A substantial amount of the Indiana State budget is spent on road repair and maintenance from damage caused by landslide. The landslide remedial technique frequently applied by the Indiana Department of Transportation (INDOT) is the excavation and backfill method, which in most instances is successful. However, in many cases more liberal landslide treatments may be applied that would arrest movement, provide a sufficient safety factor, and at a lower cost. The objective of this study is to propose economically feasible landslide remedial methods that may be …

Methods Of Corrosion Protection And Durability Of Concrete Bridge Decks Reinforced With Epoxy-Coated Bars - Phase I, Lisa Michele Samples, J. A. Ramirez

JTRP Technical Reports

In this study, the results of an extensive field and laboratory investigation conducted to evaluate the corrosion performance of epoxy-coated reinforcement are reported. One hundred and twenty three concrete bridge decks containing epoxy-coated reinforcement, uncoated reinforcement, and various other corrosion protection systems were included in a field investigation. An initial visual inspection of these bridge decks showed that 44% had signs of distress from corrosion of the reinforcement. Six decks, representing 5% of the total sample, were selected for a second more detailed survey. Three of the six decks had epoxy-coated reinforcement. This number represents 11% of the total sample …

Pile Design Based On Cone Penetration Test Results, Rodrigo Salgado, Junhwan Lee

JTRP Technical Reports

The bearing capacity of piles consists of both base resistance and side resistance. The side resistance of piles is in most cases fully mobilized well before the maximum base resistance is reached. As the side resistance is mobilized early in the loading process, the determination of pile base resistance is a key element of pile design. Static cone penetration is well related to the pile loading process, since it is performed quasi-statically and resembles a scaled-down pile load test. In order to take advantage of the CPT for pile design, load-settlement curves of axially loaded piles bearing in sand were …

Reconciled Platoon Accommodations At Traffic Signals, Jay Wasson, Montasir Abbas, Darcy M. Bullock, Avery Rhodes, Chong Kang Zhu

JTRP Technical Reports

The use of microprocessor-based traffic signal controllers introduced in the 1960s has allowed for the development of many new strategies to make traffic signal systems more responsive to traffic conditions. Many efforts have focused on the development of real-time, adaptive control strategies. While some of these strategies have been shown to improve intersection performance, there are several factors that have limited their deployment. Some of these include substantial capital cost, complicated calibration procedures, and the reluctance of practicing engineers to deploy strategies radically different from those currently in use. Therefore, lower cost strategies that are compatible with existing infrastructure continue …

Steel Bridge Protection Policy: Evaluation Of Bridge Coating System For Indot Steel Bridges, Luh M. Chang, Tarek Zayed, Jon D. Fricker

JTRP Technical Reports

The study identifies various painting systems that are successfully used in Indiana’s surrounding states and other industries. The identified systems are further screened and evaluated. After prudently comparing INDOT’s inorganic zinc / vinyl system with the waterborne acrylic system, the moisture cure urethane coating system, and the 3-coat system of zinc-epoxy-urethane, the results show that the new 3-coat system fulfills INDOT’s needs with the most benefits. Therefore, the 3-coat system is recommended to replace INDOT present inorganic zinc / vinyl system. To deal with the problems facing the lead-based paint, a comparison between full-removal and over-coating alternatives is made. Results …

Control Of The Air: The Enduring Requirement, Richard P. Hallion

United States Air Force: Publications

Throughout the military history of the twentieth century, the role of aerospace forces has become more predominant. Today, wars typically start, are prosecuted, and reach their decisive culminating point--whether surrender of a foe, agreement to a ceasefire, or the ceasing of combat operations--thanks to air action. Given these circumstances, to lose control of the air is to lose a war, particularly in an era (as we now are in since the end of the Cold War) when deployable overseas forces are small, and, thus, particularly vulnerable to the tremendous leverage an opponent gains by sudden and swift air attack. If …

Improvements In Modeling Dissolved Oxygen In Activated Sludge Systems, Jacek Makinia, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The aim of this research was to show the impact of the flow conditions and variations in the aeration intensity on changes in the predicted dissolved oxygen (DO) concentrations in a full-scale activated sludge reactor. The Activated Sludge Model No. 1 was used to describe the biochemical processes. The studies were performed at the Rock Creek wastewater treatment plant in Hillsboro, OR (USA). The simulation results were compared with data originating from two 24-hour experiments. The model that best reflected the spatial and diurnal distributions of the DO concentrations was the one-dimensional advection-dispersion equation with a variable overall oxygen mass …
