Use Of Waste Materials In Highway Construction, Imtiaz Ahmed

JTRP Technical Reports

This study synthesizes the information on the use of waste materials in highway construction. The information was obtained from a review of published literature supplemented by: recent unpublished reports, presentations of research updates by professionals at different forums, anti personal meetings with the experts. In addition, a questionnaire regarding the use of waste materials was prepared and distributed to each of the state highway agencies. A majority of states responded to the questionnaire, giving a summary of current practices in the use of waste materials in highway construction and their experiences on the technical, environmental, and economic aspects of the …

Limits Of Limit Equilibrium And Finite Element Techniques Applied To Cracked Debris Dams On Collapsing Foundations, Stanley Soliday Jr.

Dissertations and Theses

Limits of slope stability, limit equilibrium methods, and of the finite element code FEADAM are reached in the application of these methods to the problem of cracked dams constructed on collapsing soils.

Repair/Rehabilitation Of Deteriorated Drainage Pipe, Bob G. Mccullouch

JTRP Technical Reports

This report describes the current technologies, methods and materials used in drainage pipe rehab and replacement. It also identifies which of these technologies can be applied for the various pipe material types. Installed cost information was obtained from the states in the survey and from vendors for the various methods. In describing each method, equipment requirements and limitations are reported. From this report, one should be able to understand what method is appropriate for the various repair problems and pipe types.

Engineering Soils Map Of Jay County, Indiana, Arvind Chaturvedi, Andrew Garrigus

JTRP Technical Reports

The soils mapping of Jay County was done primarily by the analysis of landforms and associated parent materials as portrayed on stereoscopic aerial photographs. Valuable information for soils was obtained from publications of the Soil Conservation Service, United States Department of Agriculture. Test data from roadway and bridge projects was obtained from the Indiana Department of Transportation. Soil profiles for the landform/parent material areas mapped are presented on the engineering soils map, a copy of which is included at the end of the report.

User Guide For Pc-Stabl3d, Gennady Moshkovich

JTRP Technical Reports

PC-STABL3D is the program for IBM PC compatible computers, developed to handle general stability analysis of three-dimensional slopes. Random generation routines are invoked to create trial failure surfaces, which are analyzed using the limiting equilibrium approach. The current version of PC-STABL3D is enhanced by a graphical pre/postprocessor, which facilitates creation and edition 0 data files, examination of problem geometry, and analyzing of the obtained failure surfaces. After the failure surfaces are generated and their factors of safety are computed, the program performs statistical analysis of received factors of safety, and calculates minimum statistical factor of safety. The information about minimum …

Application Of Rapid Asphalt Content Test To Slag Mixes, Douglas Windslow

JTRP Technical Reports

The "nuclear" asphalt content gage was used with bituminous mixes containing slag aggregates to assess its applicability as a rapid analysis tool for these types of mixes. It was found to work as well, or better, than the standard extraction technique. It was also found to have additional advantages over the extraction technique since it is about an order to magnitude faster, requires no solvent and involves no decisions on the part of the user.

User's Manual For The Software "Tfpi" That Implements The Traffic Forecasting Procedure For Indiana, Sunil K. Saha, Jon D. Fricker

JTRP Technical Reports

A program has been written in Microsoft QuickBASIC to implement the traffic models developed for both rural and urban Indiana state highway segments during a two-phase HPR Project carried out for the Indiana Department of Transportation. The report ''TRAFFIC VOLUME FORECASTING METHODS FOR RURAL STATE HIGHWAYS" describes the models developed in Phase 1 of the study, while the report "THE DEVELOPMENT OF A PROCEDURE TO FORECAST TRAFFIC VOLUMES ON URBAN SEGMENTS OF THE STATE AND INTERSTATE HIGHWAY SYSTEMS" describes the models developed in Phase 2. For rural interstates, new models have been developed in Phase 2 that supercede the Phase …

Accident Reduction Factors For Indiana, Daniel Joseph Ermer, Kumares C. Sinha

JTRP Technical Reports

This report presents the results of a study conducted to develop appropriate accident reduction factors associated with various highway improvement projects in Indiana. The factors were developed through a before-and-after analysis of accident data from 1983 to 1987. Disclaimer: This report presents the results of statistical analyses applied to available data. The accident reduction factor values do not imply any endorsement of any particular project types by the Federal Highway Administration or the Indiana Department of Transportation or the Joint Highway Research Project of Purdue University.

The Impact Of Highway Services And Expenditures On Regional Economic Development, Paulus Cornelius Lombard, Kumares C. Sinha, Deborah J. Brown

JTRP Technical Reports

This report presents results from a study to determine the relationship between highway infraatructure and economic development in Indiana. Regression models and a computer model were developed to estimate the annual long-term impacts of highway construction on economic growth. Results from an analysis of economic impacts of the construction of 13 four-lane highway sections in Indiana, as well as an analysis of national data concerning industrial location determinants, are also presented.

Driving Of Thin Shells For Steel Encased Concrete Piles, G. Agrawal, Jean-Lou Chameau

JTRP Technical Reports

The major purpose of this study was to identify the causes for the driving difficulties often given experienced on highway projects where thin shells are used for cast-in situ concrete piles that support bridge approaches, and to develop a set of recommendations and procedures to enable INDOT engineers to (a) make use of available technology for dynamic analysis of pile driving; and (b) make appropriate changes in the design, construction and contract specification procedures to improve identification and correction of problems at the earliest possible stage.

This study indicates that the parameter of greatest importance for most projects is the …

Continuum Modeling Methodology For Dynamic Behavior Of Towers, Khaled A. Obeid

Civil & Environmental Engineering Theses & Dissertations

A very common problem in Civil Engineering is the analysis and design of lattice structures. These types of structures generally consist of repetitive sections and have been utilized in the erection of transmission and communication towers, space roof trusses, solar energy collectors, and space platforms. Since lattice structures consist of a significantly large number of members and subsequently a large number of nodes, the classical discrete technique of analysis can be very expensive even on today's modern computers. This study applies a rational approach which capitalizes on the repetitive nature of towers to develop the equivalent continuum model for the …

Micromechanics Of Granular Materials And Its Relation To Wave Velocity, Tarun K. Agarwal

Civil & Environmental Engineering Theses & Dissertations

The macro characters of the granular materials depend upon micromechanical parameters such as the void ratio, particle shape, contact force distribution, and initial state of the fabric of the assembly. Since it is difficult to evaluate these internal parameters from laboratory experiments, a macro measure is desired which depends directly on these internal parameters. One such measure has been shown to be dynamic shear modulus but it was incomplete in predicting directional changes in the internal parameters. Therefore, it is hypothesized here that the complete elastic moduli matrix will have more direct information about the internal parameters, especially the dynamic …
