Investigation Of Collapse Of Long-Span Structure Under Ky 80 In Floyd County, Ronald D. Hughes, David L. Allen, Robert C. Deen Nov 1986

Investigation Of Collapse Of Long-Span Structure Under Ky 80 In Floyd County, Ronald D. Hughes, David L. Allen, Robert C. Deen

Kentucky Transportation Center Research Report

The Kentucky Transportation Research Program (KTRP) was requested to obtain and review design, construction, and post construction documents relative to the long-span structure under KY 80 in Floyd County. Telephone and in-person contacts were made with various agency officials involved with the structure in an endeavor to collect pertinent data. Documents that were initially presented to KTRP staff were thoroughly reviewed and a draft report based upon information submitted was prepared. The draft report included a scenario relating to a probable sequence of events that could have been significant in the ultimate collapse of the structure.

Soon after distribution of …

Lime Stabilization Of Pavement Subgrade Soils Of Section Aa-19 Of The Alexandria-Ashland Highway, Tommy C. Hopkins, David L. Allen Oct 1986

Lime Stabilization Of Pavement Subgrade Soils Of Section Aa-19 Of The Alexandria-Ashland Highway, Tommy C. Hopkins, David L. Allen

Kentucky Transportation Center Research Report

The purposes of this study were to evaluate the effects of hydrated lime on the soils from Section AA-19 of the Alexandria-Ashland Highway and determine if the engineering properties of the soils from Section AA-19 could be improved by lime stabilization. Soil samples used in the study were obtained by· the Kentucky Transportation Research Program on March 25, 1986. Three bag samples were collected from Section AA-19 (Lewis County, Kentucky) of the Alexandria-Ashland Highway, Stations 1630 (Sample A), 1495 (Sample B), and 1675+50 (Sample C), respectively. Based on a review of the geology of Section AA-19, the three sampling sites …

Manual On Bridge/Culvert Maintenance, Gary W. Sharpe, Theodore Hopwood Ii Sep 1986

Manual On Bridge/Culvert Maintenance, Gary W. Sharpe, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

The basic objective of this course is to provide background (introductory) technical information that will aid the manager of bridge/culvert installations. In most instances, information presented may not be sufficiently complete for the student to perform the required work. However, the intent is more to familiarize than to instruct In many instances, professional engineering and experienced labor are necessary to ensure successful completion of tasks. Once the local official responsible for bridges and culverts has completed this workshop, he should have a basic understanding of

  • the most common bridges/culverts encountered in counties and municipalities,
  • the major components of common bridge/culvert …

Agenda: Getting A Handle On Hazardous Waste Control, University Of Colorado Boulder. Natural Resources Law Center Jun 1986

Agenda: Getting A Handle On Hazardous Waste Control, University Of Colorado Boulder. Natural Resources Law Center

Getting a Handle on Hazardous Waste Control (Summer Conference, June 9-10)

The conference chairman was University of Colorado School of Law professor Lawrence J. MacDonnell.

During the past ten years Congress has made the regulation of hazardous waste a priority. This conference focuses on the Resource Conservation and Recovery Act, as amended in 1984, and the Comprehensive Environmental Response, Compensation and Liability Act.

This conference attracted about 100 registrants from 16 states plus the District of Columbia. John G. Welles, Regional Director for EPA Region 8, presented a luncheon address.

Effects Of Load Distributions And Axle And Tire Configurations On Pavement Fatigue, Herbert F. Southgate, Robert C. Deen Apr 1986

Effects Of Load Distributions And Axle And Tire Configurations On Pavement Fatigue, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

Damage factor relationships for axle and tire configurations are presented. Adjustment factors are provided to account for variations in load distributions within axle groups, distances between axles of a tandem, and variations in tire pressure for both dual and flotation tires.

Properly accounting for accumulated fatigue of a pavement requires a traffic volume, proportions of vehicle styles (classifications) within the of service, estimate of the average damage factor for each classification, reasonable measure of traffic stream, dates and estimates of tire contact pressures.

All adjustment factors presented are based on analyses of a limited number of structures and should be …


Use Of Nondestructive Testing To Prevent Failures Of In-Service Metal Bridges, Theodore Hopwood Ii, Robert C. Deen Apr 1986

Use Of Nondestructive Testing To Prevent Failures Of In-Service Metal Bridges, Theodore Hopwood Ii, Robert C. Deen

Kentucky Transportation Center Research Report

The failure of metal bridges, subject to in-service fracture problems mainly caused by fatigue, may be prevented or minimized by performance of periodic nondestructive testing. Attendant factors that justify funding for such inspections include the potential for bridge failure, the consequences of bridge collapse, risk analyses, and inspection strategies. Factors that affect structural integrity include structural design, construction quality, and service loadings.

Details of a computer/strain-gage system capable of obtaining strain-gage data from critical structural elements are described. Data are processed to determine the stress-range distribution, number of stress cycles, resolved mean stress range, need for structural inspection, critical crack …

Evaluation Of A Full-Depth Asphaltic Concrete Pavement, Herbert F. Southgate, Gary W. Sharpe, Mark Anderson Apr 1986

Evaluation Of A Full-Depth Asphaltic Concrete Pavement, Herbert F. Southgate, Gary W. Sharpe, Mark Anderson

Kentucky Transportation Center Research Report

This study was initiated to verify a newly-developed set of design curves for full-depth asphaltic concrete pavements. Quality control during construction was checked using nuclear density testers, Benkelman beams, and a Road Rater. During the course of this study, an analysis system (predicated upon the elastic theory model) was developed to interpret the dynamic deflections as measured by the Road Rater. The thickness design curves were verified by elastic theory and deflection testing within the accuracy of construction variations.

Measured rut depths were analyzed in terms of potential rut depth resulting from consolidation under traffic due to lack of obtaining …

Flexible Engineering Software: An Integrated Workstation Approach To Finite Element Analysis, Brant Arnold Ross Apr 1985

Flexible Engineering Software: An Integrated Workstation Approach To Finite Element Analysis, Brant Arnold Ross

Theses and Dissertations

One obstacle preventing more engineers from using finite element analysis (FEA) is the difficulty of transferring data between steps in the modeling process. A Fortran computer program, Rosetta.BYU, has been developed to open data paths between finite element preprocessors (mesh generators) and finite element analysis programs, using a custom data structure. It accepts neutral data files, Version 2.0 IGES data files, and Movie.BYU files for input/output. An application of Rosetta is described. A general workstation manager program, Davinci.BYU, is reviewed that provides a support layer between the engineer and the operating system, organizes software and data files, and facilitates on-line …

Comparison Of Contained Rock Asphalt Mat (Cram) With Conventional Asphaltic Concrete Pavements, Herbert F. Southgate, David L. Allen, Robert C. Deen Jan 1985

Comparison Of Contained Rock Asphalt Mat (Cram) With Conventional Asphaltic Concrete Pavements, Herbert F. Southgate, David L. Allen, Robert C. Deen

Kentucky Transportation Center Research Report

A brochure proposing the use of "Contained Rock Asphalt Mat" (CRAM) provided a comparison of stress distributions throughout a CRAM structure (Figure 1) as compared to a conventional pavement (Figure 2). Experience has indicated that stress distributions do not always present the most sensitive or appropriate analysis of a pavement structure. Distributions of strains, and more particularly "work", are better indicators of load distributions throughout a pavement structure and subsequent performance.
