Integration Of Real-Time Air Pollution Parameters Into The Decision Making Process Regarding Highway Construction Work Zone Traffic Flow Requirements (Phase 1), Ouattara Fatogoma, Todd A. Premo, Robert Bertram Jacko

JTRP Technical Reports

The Midac Fourier Transform Infrared air monitoring system was used to measure real-time vehicular exhaust emission concentrations of carbon monoxide (CO) and hydrocarbons (HCs) during the Purdue Vehicle Emission Monitoring and Modeling Project (PVEMP) conducted in spring and summer 1997. The experiments took place on the Borman Expressway, in Gary. Indiana and on 1-65, south of Lafayette, Indiana Concurrently, two speed-readings were acquired from the passing vehicles in the vicinity of the air monitoring system using a hand-held laser gun. The speeds were integrated to determine the speeds and accelerations of the passing vehicles at the spectrometer. An 8-mm camcorder …

Modeling And Optimization Of The Indiana Lane Merge Control System On Approaches To Freeway Work Zones, Part I, Andrzej P. Tarko, Sreenivasulu R. Kanipakapatnam, Jason S. Wasson

JTRP Technical Reports

Severe traffic turbulence on entry sections of freeway work zones increases the delays and risk of crash. A new Indiana Department of Transportation system called Indiana Merge Lane System (IMLS) creates a dynamic no passing zone on the approach to the freeway work zone through the sequence of DO NOT PASS signs. The system is thought to encourage drivers to switch lanes well upstream of the discontinuous lane taper where the merging maneuver is safer and less intrusive. The IMLS is expected to impact drivers’ behavior, their perception of the traffic conditions, and traffic safety.

This research is focused on: …

Identification And Quantification Of Radionuclides In Coal Ash, James E. Alleman, Franklyn M. Clikeman, Thomas Skronski

JTRP Technical Reports

One of the important environmental issues raised recently in regard to coal ash reuse for highway construction purposes (e.g., embankment development) is that of worker, and public, exposure to radiation which might possibly be emitted by these types of residuals. Radiation emission is, in fact, a natural phenomenon for most materials, both natural and man-made, but in the case of coal ash residuals the process of combustion produces an inevitable concentration of radionuclides from the original virgin coal. INDOT’s corresponding environmental concern consequently focuses on the following basic question: does this magnification of radionuclides found within these coal ash residuals …

Performance Evaluation Of A Highway Embankment Constructed Using Waste Foundry Sand, Barry K. Partridge, James E. Alleman

JTRP Technical Reports

Over 9 million Mg of waste foundry sands (WFS) are produced annually in the United States as a by-product of the metal casting industry. The majority of WFS are deposited in restricted or sanitary waste landfills. Considerable savings is available to the metal casting industry through the development of reuse applications for their WFS and generators are often willing to provide WFS to a job site at no cost to the end user. Laboratory investigations have indicated that WFS from ferrous foundries can provide the necessary engineering properties for a highway embankment and that the MicrotoxTM bioassay test can be …

Building Embankments Of Fly/Bottom Ash Mixtures, Ahmed M.K. Karim, C. W. Lovell, Rodrigo Salgado

JTRP Technical Reports

This research investigates the engineering properties of mixtures of bottom ash and Class F fly ash relevant to their utilization in highway embankment construction. The research included ash samples from two major power plants in Indiana that disposed of their ash differently. The first power plant disposes of the bottom ash and fly ash separately and hence explicit mixtures were synthetically formed and tested. The second power plant disposes of the bottom ash and fly ash together in a common location and hence they become homogeneous samples for the research. Characterization of the ash included grain size analysis, specific gravity, …

Testing Of Multi-Span Bridges With Full Span Precast Prestressed Concrete Panels (Phase 1), Robert J. Peterman, J. A. Ramirez

JTRP Technical Reports

The purpose of this study was to assess the behavior and durability of multi-span bridges constructed with full-span prestressed concrete form panels. The use of full-span prestressed concrete form panels for bridges with spans of 40 ft. or less is an economical method of construction due to the reduction of on-site formwork and labor required by alternate cast-in-place systems. In this research, a pair of two-span bridges utilizing full-span prestressed concrete form panels were fabricated and tested in the Karl H. Kettelhut Structural Engineering Laboratory at Purdue University. Time-dependent effects were monitored during the cast-in-place (CIP) concrete cure period of …

Determining The Viability Of The "Rated Axle Load Enhancement System" For Concrete Pavement, Chih-Jen Lee, Charles D. Sutton, Thomas D. White

JTRP Technical Reports

Concrete pavements in large part are designed as flat slabs although in the past they have included thickened edges. Thickened edge slabs are used today where positive load transfer for some reason cannot be provided. The Rated Axle Load Enhancement (RALE) system concept involves the use of longitudinal stems to stiffen the concrete slab. A close analogy is that of a wide double or quadruple "T" beam. The stems may be rectangular or trapezoidal.

In this study, RALE systems with two and four rectangular stems as well as plain concrete slabs were analyzed using the finite element method (FEM). The …

Automating Field Data Collection In Maintenance Operations, Bob G. Mccullouch

JTRP Technical Reports

Field data collection and management in DOT organizations requires a considerable amount of resources in the form of personnel and management systems. Recent studies performed by the researcher revealed that an average of 30-50% of some field supervisory personnel's time is spent on processing field data paperwork. This is a considerable amount of time spent on an undesirable task and is taking these employees away from more important job duties. This project automated two maintenance field data collection functions. One was a Crew Day Card, which is a card used by a maintenance crew to document the activity performed. Information …

Study Of Side Ditch Liners For Highway Application, Anthony S. Calderon, Philippe L. Bourdeau

JTRP Technical Reports

Over the past few years, the INDOT new materials department has received numerous erosion control products (mostly geosynthetics) to evaluate as alternatives to riprap and concrete in ditch liners. Potential benefits include lower construction costs and better aesthetics over current products. Unfortunately, no specification, design methodology, or classification system currently exists for these erosion control blankets.

In this project's phase I, existing information and knowledge on erosion control materials used to line highway side drainage ditches were investigated. From the available technical1iterature (journal and conference publications, other DOTs specifications, manufacturer documentation, independent test laboratory test data), design methodologies, classification system, …

Development Of A Procedure To Identify Aggregates For Bituminous Surfaces In Indiana, Douglas W. Bruner, Jung Chan Choi, Terry R. West

JTRP Technical Reports

Adequate friction resistance is needed to prevent pavement slipperiness and to allow vehicles to stop in a reasonable distance. In stone mastic asphalt surfaces, friction resistance is mainly a function of the interaction between the aggregates exposed at the road surface and the vehicle tires. Performance of the aggregate is reduced over time by wear and polishing as a consequence of vehicular traffic. In this research a method to investigate aggregate performance based on physical, chemical and petrographic factors has been evaluated. The objective was to develop a laboratory method to test Indiana dolomite, limestone, sandstone, and gravel aggregates to …
