Identification, Analysis, And Correction Of High-Accident Locations In Kentucky, Charles V. Zegeer, Kenneth R. Agent, Ronalds L. Rizenbergs

Kentucky Transportation Center Research Report

The first step in the highway safety improvement process involves reporting and summarizing accidents by location. Once the high-accident locations are identified, field investigations and analysis follow. Locations are ranked on the basis of potential for accident reduction. Safety improvements are then scheduled and implemented. Finally, improvements are evaluated in terms of accident reduction.

This report compiles, in detail, the process involved in arriving at safety improvements in the high-accident spot-improvement program. References are made to information and methodologies developed in earlier reports by the Division of Research of the Kentucky Department of Transportation. Most of the background information and …

Design Guide For Bituminous Concrete Pavement Structures, James H. Havens, Robert C. Deen, Herbert F. Southgate

Kentucky Transportation Center Research Report

To determine pavement thicknesses from design charts and tables, it is necessary to know only the EAL's (equivalent axle loads), the CBR of the subgrade soil, and the modulus of elasticity of the bituminous concrete. Charts permit selection of pavement structures employing alternative proportions of bituminous concrete and crushed stone base. Total thickness varies according to the proportions chosen. It is implicitly intended that the selection of alternative structures be based on engineering considerations, such as 1. estimates of comparative construction costs, 2. compatibility with cross section template and shoulder designs, 3. uniformity or standardization of design practices, 4. highway …

Analysis Of Time-Deflection Consolidation Data, E. Gregory Mcnulty

Kentucky Transportation Center Research Report

A computerized statistical curve-fitting algorithm has been developed for determining the time-dependent properties of conventional (load-incremental) consolidation test data. Analytical models of the graphical methods developed by Taylor and Casagrande and of the Naylor-Doran method of successive approximations determtne values for the coefficients of consolidation, permeability, and the values of deflection corresponding to the begimltng and endtng of primary consolidation. The coefficients of volume change and secondary compression are also calculated. A modified statistical definition is used to select the linear portions of the data curves and is applicable to other data-fitting problems. After the Naylor-Doran method has been used, …

Structural Capacity Of In-Place Asphaltic Concrete Pavements From Dynamic Deflections, Herbert F. Southgate, Gary W. Sharpe, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

The proper design of asphaltic overlay thicknesses involves four major factors; the in-place modulus of the subgrade, an estimate of the structural capacity of the existing pavement, estimates of the future traffic expressed as equivalent axleloads and required or desired design levels, and a thickness design procedure. This paper deals with estimating the in-place subgrade modulus and the remaining load-carrying capacity of the existing pavement. The method presented herein is valid for any Road Rater or other dynamic tester such as the Dynaflect. This procedure was based upon a 600-pound (272.4-kg) peak-to-peak dynamic load applied at a rate of 25 …

Identification Of Kentucky Shales, Tommy C. Hopkins, Brian C. Gilpin

Kentucky Transportation Center Research Report

Results obtained from a series of engineering tests performed on 40 different types of shales are summarized and discussed. Both hard and soft shales, as well as shales having well-documented histories of involvement in highway embankment failures and shales having little known involvement, were tested. A major portion of the report examines the suitability of the slake-durability tests, originally devised by Franklin-Chandra of England, as a means of broadly characterizing the engineering properties of Kentucky shales. Results obtained from ten different slake-durability testing procedures, which include procedures proposed by Franklin and Chandra and others as well as procedures devised during …

The Status Of Sulfur Fertilization Of Crops In Kentucky, Lloyd W. Murdock

Soil Science News and Views

Sulfur has long been recognized as being essential for the growth of plants and animals due to it being necessary for production of several amino acids. Although regarded as a "secondary" element, it is required by plants in fairly high amounts, very similar to that of phosphorus. Sulfur deficiency symptoms in plants are somewhat similar to those of nitrogen since an overall uniform pale-green leaf color develops. Sulfur deficiencies are often found in crops growing on sandy soils with low organic matter content.

Compensatory Damages In Federal Fair Housing Cases, Robert G. Schwemm

Law Faculty Scholarly Articles

The federal fair housing laws became effective in 1968. Since then, courts have often awarded damages to victims of housing discrimination, but their decisions have provided little guidance for assessing the amount of such awards. There is a great range of awards, with some courts awarding only nominal damages of $1 and others setting awards of over $20,000. Compounding the problem is the difficulty of measuring the principal element of damages claimed by most plaintiffs in fair housing cases, noneconomic emotional harm or other forms of intangible injury.

Rarely is the basis for the amount of the court's award satisfactorily …

Evaluation Of Rumble Strip Design And Usage, Jerry G. Pigman, Michael M. Barclay

Kentucky Transportation Center Research Report

The objective of this study was to investigate the following aspects of rumble strips: the optimum height and width of elements in a rumble strip pattern, spacing between them, the effect of grouping elements into sets, the effects of speed on design criteria, and driver reaction to the audible and physical stimuli produced by rumble strips. A survey of design and usage in other states was conducted; and the results show that even though 35 of the 44 responding states have installed rumble strips, only five have warrants for usage.

Two types of rumble strip design were evaluated -- one …

Evaluation Of Watertight Bridge Expansion Joints, Wm. Vernon Azevedo

Kentucky Transportation Center Research Report

Engineers have long recognized the importance of bridge expansion joints. The inadequacy in design of such joints has also been realized. Proprietary products are now available which may eliminate well-documented problems associated with bridge expansion.

The objective of this study was to evaluate the field performance of such products.

Vehicle Noise Emission Levels In Kentucky, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objectives of this study were to update individual vehicle noise data taken in previous years in Kentucky and to determine reference mean energy emission levels for Kentucky vehicles for use in the SNAP 1 noise prediction procedure.

Comparison of Kentucky and nationwide emission levels showed a close agreement for medium and heavy trucks; however, automobile noise levels in Kentucky were higher than nationwide levels. An analysis of emission levels of the various vehicle types showed that a fourth category, light trucks, may need to be added. The Kentucky emission levels were input into SNAP 1 in place of the …

Identification And Rehabilitation Of High-Risk Drivers, Kenneth R. Agent

Kentucky Transportation Center Research Report

This report deals with the identification and rehabilitation of high-risk drivers. Methods used to identify negligent drivers were examined. Kentucky's point system was compared to those tn other states. The consequences of drivers attending driverimprovement clinics were studied by analyzing driving records.

The analysis showed that accident involvement was directly related to the accumulation of penalty points and number of violations. Definite relationships were found between several specific types of violations and accidents.

A very significant improvement in driving records was noted for those drivers who completed a driver-improvement clinic; however, a similar improvement occurred for drivers eligible for the …

Ohio River Suspension Bridges: An Inspection Report, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

For many years, suspension bridges have been employed to economic advantage where long uninterrupted spans were required. While they have been supplanted for most common applications by cantilever and arch bridges in the United States, suspension bridges are a valid design type. Two American suspension bridges have been in service for over 100 years. A new form of suspension bridge, the cable-stayed bridge, is widely used in Europe and is expected to be as popular in the United States.

The key to the success of suspension bridges lies in the use of high-strength wires that are consolidated into the main …

Traffic Accidents In Kentucky (1978), Kenneth R. Agent

Kentucky Transportation Center Research Report

Highway locations having an abnormal history of accidents should be identifiable in some way. Average and critical accident numbers and rates must be known for similar locations. Averages have been determined previously for rural highways, but it is necessary to update those numbers and to determine rates for urban areas. A detailed picture of traffic accidents in Kentucky in 1978 is presented.

Average rates in terms of accidents per 100 million vehicle-miles (160 million vehicle-kilometers) were calculated for various classifications of rural and urban highways. Also, average rates in terms of accidents per million vehicles were determined for 0.3-mile (0.48-km) …

Evaluation Of Raised Pavement Markers In Kentucky: Statewide Installations; 1975-1979, Jerry G. Pigman, Kenneth R. Agent, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

Raised markers have become commonplace in delineation on highways in states where snowfall is minimal and snowplows are not needed. They have proven to be especially effective for wet, nighttime, and other poor visibility conditions when paint stripes are least effective. In Kentucky, over one million raised markers have been installed and damage from snowplowing has been significant during some of the more severe winters. As a result of costs associated with replacing damaged markers and requirements of the Pavement Marking Demonstration Program, an evaluation of all installations was undertaken.

Between 1975 and 1979, a total of 1,082,250 markers were …

Strain-Rate Selection In The Constant-Rate-Of-Strain Consolidation Test, C. Thomas Gorman

Kentucky Transportation Center Research Report

Constant-rate-of-strain (CRS) consolidation tests were performed on remolded kaolinite specimens. The effect of strain rate on CRS test data is shown. A relation between soil parameters and strain rate was developed and used to formulate a strain-rate selection procedure. The fmal selectlon procedure is based on liquid limit and initial degree of saturation of the specimen and is presented in graphical form. The procedure is applicable to all types of soils.

Applying The International Law Of Sovereign Immunity To The States Of The Union, John M. Rogers

Law Faculty Scholarly Articles

A state of the Union may preserve its immunity from suit in its own courts, and the Constitution restricts its amenability to suit in the federal courts. Yet in Nevada v. Hall the Supreme Court held that in a motor-vehicle accident case a state cannot claim a constitutional immunity from suit in the courts of a sister state. The Court indicated, however, that if a suit involved a defendant state's “capacity to fulfill its own sovereign responsibilities,” different constitutional considerations might control. In vigorous dissents Justices Blackmun and Rehnquist argued that the reasoning of the majority precluded even this possibility. …
