Review Of Pertinent Contract Documents Tennessee-Tombigbee Waterway Divide Cut Section 3a, Ronald D. Hughes, Robert C. Deen, David L. Allen, Tommy C. Hopkins

Kentucky Transportation Center Research Report

During construction of a portion of the Tombigbee Canal near Corinth, Mississippi, southward from Pickwick Lake (Station 13,118+00 to 13,337+50), the Contractor reported various problems, which he termed "differing site conditions." Some of the items considered as problems by the Contractor were: the amount of cherty Paleozoic material was far less than he expected or anticipated, there were deep deposits of bluish muck, the alluvial was not sufficiently stable to place in 1-foot lifts, excessively wet materials made it necessary to shift equipment frequently, the equipment had to travel over bad roads, and the materials had no bearing strength.

Strain Energy Analysis Of Pavement Designs For Heavy Trucks, Herbert F. Southgate, Robert C. Deen, Jesse G. Mayes

Kentucky Transportation Center Research Report

The first portion of this paper summarizes classical concepts of work, or strain energy, as applied to the analysis of stresses, strains, and deflections under various vehicular load configurations on pavement systems. Controlling equations for strain energy density are presented. When considering strain energy density, strain energy, or work, all components of stresses or strains must be taken into account so that total internal behavior can be evaluated. Previously, pavement thickness design systems have been developed using only a single component of strain, typically at the bottom of the asphaltic concrete layer or at the top of the subgrade. Strain …

Removal Of Fluoborate From Electroplating Rinse Water By Ion Flotation, Ray Haralson

Dissertations

A problem exists in the removal of fluoborate from electroplating waste rinse water. The normally used waste treatment methods are not effective and the vacuum evaporation process now being tried is expensive and energy intensive. Experiments were conducted and an alternative treatment process which shows substantial removals of the fluoborate was developed. This can be effectively done using ion flotation techniques. A broad range of surfactants were screened for usefulness in this process and it was found that an aliphatic amine acetate was usable in this process. Operating parameters for the process were investigated, and the removal mechanism was determined …

Nonlinear Analysis Of Shear Walls And Shear Panels By Finite Element Method, Erhan Atay

Theses

The objective of this work was to determine the feasibility of applying the Finite Element Method to Nonlinear Analyses of Shear Walls and Shear Panels.

Various existing methods are reviewed and discussed.

These studies determined that the application of Finite Element Method to Nonlinear Analysis of Shear Walls and Shear Panels is being misused in many cases but is very practical and promising where justified. However more studies are needed for the manner of modeling to be used to connect the wall to beam and slab elements that frame into that wall. To model the coupled beams as plane stress …

Effects Of Construction Variations Upon Dynamic Moduli Of Asphaltic Concrete, Herbert F. Southgate

Kentucky Transportation Center Research Report

The two variables that most influence the behavior of asphaltic concrete pavements are subgrade modulus and thickness of the asphaltic concrete. Other significant variables are: temperature of the asphaltic concrete, asphaltic concrete modulus, frequency of the dynamic loading, asphalt content by weight in mix, and voids in the asphaltic concrete mix.

During a series of Road Rater tests on a experimental pavement in Kentucky, deflection test data varied widely from expected values. Test data reported by Kallas and Riley permitted the development of an equation relating asphaltic concrete modulus to its temperature and to the frequency of loading. However, after …

Engineering Properties Of Kentucky Oil Shales, Vincent P. Drnevich, Tommy C. Hopkins, David L. Allen, Samuel S. Hale

Kentucky Transportation Center Research Report

Excavation, handling, and the environmentally safe disposal of spent oil shale and overburden materials require a knowledge of their geotechnical engineering properties. To determine these properties a laboratory investigation of the physical and geotechnical engineering properties was made. The physical tests consisted of mechanical analyses, Atterberg Limits, and specific gravity determinations. Geotechnical properties were determined by moisture-density analyses, triaxial compression, permeability tests, slake-durability, one-dimensional compression tests, and Los Angeles abrasion. A one-dimensional compression test was devised to address the problem of placement, loading, and saturation of the spent shales and overburden materials. The compacted, unprocessed oil shales were more susceptible …

Warrants For Left-Turn Lanes, Kenneth R. Agent

Kentucky Transportation Center Research Report

Warrants for the installation of separate left-turn lanes were developed. Literature was reviewed, and policies and practices in other states were surveyed. Accident analyses of locations with and without separate left-turn lanes were conducted. Computer simulation was used to determine relationships among traffic delay, load factor, traffic volume, percent left-turns, cycle length, and cycle split. The relationship between left-turn accidents and conflicts was investigated.

Warrants were developed involving the following three general areas:

1. accident experience,
2. volumes (based on delay), and
3. traffic conflicts.

Mechanical Properties Of Kentucky Oil Shales As Related To Mine Design Application, Tom F. Fudge Jr., David L. Allen, Tommy C. Hopkins

Kentucky Transportation Center Research Report

To develop oil shales as an alternate energy resource, it will be necessary to develop appropriate mining techniques. In this regard, the mechanical properties of the ore must be determined. Section I of this paper presents data from a laboratory study to determine these properties. Uniaxial compression tests, longitudinal frequency tests, indirect tensile tests, and triaxial tests were performed. Section II uses data from section I to design an example underground mine. Strength properties are considered in the design of roof spans and pillars. It is concluded that underground mining of Kentucky oil shale is feasible with a possible extraction …

Transportation Alternatives For Peak Period Passenger Travel In Greater Georgetown, Ahamad Baksh

Theses

Alternatives to present a workable and cost effective solution(s) to the inadequate supply of public transportation during the peak hour periods in Greater Georgetown (Guyana) are examined. Various transportation system management strategies that could help in either to service the peak period demands by more effective utilization of available transport resources or to manage these demands by altering peaks patterns, are discussed. Data from the transportation study aspect of the "Physical Plan for Greater Georgetown", conducted by the Central Housing and Planning Authority as well as data from the files of the Central Transport Planning Unit of the Ministry of …

Child Restraint Usage In Kentucky (Pre-Legislation), Kenneth R. Agent, Joseph D. Crabtree

Kentucky Transportation Center Research Report

In an attempt to increase child restraint usage, a law was enacted by the 1982 Kentucky Legislature requiring use of child restraints for children forty inches or less in height. To evaluate the effectiveness of this law, a usage survey had to be completed before the law became effective. Objectives of this study were to determine statewide child restraint usage and statistics relating to improper usage. Seatbelt usage of drivers was also analyzed.

A statewide child restraint usage rate of 14.4 percent was obtained. Only 44 percent of restraints were coded as used properly. Several factors, such as population, age …
