Proposed Experimental Design And Construction Features, Kentucky Department Of Highways

Kentucky Transportation Center Research Report

PURPOSE AND OBJECTIVES: The experimental features proposed in connection with this project are three-fold: the first pertains to subsurface drainage of the pavement system, the second pertains to the feasibility of constructing full-depth, asphaltic concrete pavement sections directly on subgrade material -- rock or soil; the third pertains to the structural design and performance of pavement sections employing designated substitutions of bituminous concrete dense-graded aggregate base.

Landslides In Kentucky, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

The reoccurrence of certain features of landslides in Kentucky suggests that the difficulties in the State can be readily classified. Because of this repetitive nature, one can be alerted to the possibility of slides in certain situations early in the planning and design stages of the facility to be constructed. Thus, the traveling public might be spared the inconvenience illustrated in Figure 1. Enough cannot be said concerning the necessity for having adequate soils and geological information concerning possible routes for highway locations, and a review of a number of landslides in Kentucky suggests that there are certain troublesome geologic …

Durability Of Culvert Pipe, James H. Havens

Kentucky Transportation Center Research Report

Almost twenty years ago the Department began to develop durability data on types of culvert materials. In the interim, various stopgap as well as very judicious policies have issued. The present criterion or design practice applicable to Federal Aid projects was affirmed by the Bureau of Public Roads, May 24, 1965. Extensive field surveys have been conducted; various design innovations have been employed; and a "hot" test site has, in a demonstrative way, provided critical life-expectancy records. All past history had been documented previously; however, a brief retrospective summary will provide some continuity between forethought and certain issues now maturing.

Equivalent Axleloads For Pavement Design, John A. Deacon, Robert C. Deen

Kentucky Transportation Center Research Report

Proper structural design of highway pavements requires an evaluation of the destructive effects of the anticipated vehicular loading. The concept of load equivalency provides a means for expressing these destructive effects in terms of a single measure, the equivalent axleloads (EAL's). The design EAL's represents the equivalent number of applications of a standard or base axleload anticipated during the design life.

Florida Skid Correlation Study Of 1967 – Skid Testing With Automobiles, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The inclusion of automobiles in the Florida skid correlation study was promoted by the recognition of the following needs: 1) to compare stopping-distance measurements obtained with different instrumentation, 2) to suggest a standard method of stopping-distance testing, 3) to relate skid-resistance measurements of trailer-type testers with stopping distances of automobiles, and 4) to explore other skid-resistance measurements techniques using an automobile.

The vehicles were all full-size automobiles. Each vehicle was instrumented to measure a distance from a predetermined pressure in the brake hydraulic system to where the vehicle came to rest. Stopping distance in most of the automobiles was read …

Performance Of A Reinforced Concrete Pipe Culvert Under Rock Embankment, Robert C. Deen

Kentucky Transportation Center Research Report

A 48-inch diameter reinforced concrete pipe installation has been observed in order to evaluate the performance of both types of bedding conditions as currently used by the Kentucky Department of Highways. A portion of the pipe was laid using Kentucky's Standard B Bedding. The remainder of the pipe culvert was laid using the B₁ Bedding (imperfect trench); the design height of the fill (36 feet) was sufficient to require the imperfect trench construction. The embankment was primarily of a rock fill material, with the largest particle size limited to a maximum of 3 feet. The portion of the pipe …

Kentucky Rock Asphalt Hot-Mix Surfaces, Robert L. Florence

Kentucky Transportation Center Research Report

When this study was initiated in 1962, the objectives were disposed toward the development of Kentucky Rock Asphalt for use as a traffic-bound base and surface on rural roads near its source and toward redevelopment of the material for use as hot-mixed, hot-laid, skid-resistant surface course for higher echelon roads. Between July 1962 and August 1965, eight experimental, lean rock-asphalt bases were constructed and evaluated (1, 2, 3).

During the fall of 1965 a hot-mixed, enriched, rock-asphalt surfacing material was successfully produced through a conventional hot-mix plant and laid with a paver on a 8.4-mile section of Nolin Dam Road …

Determination Of Traffic Parameters For The Prediction, Projection, And Computation Of Ewl’S, John A. Deacon, Robert L. Lynch

Kentucky Transportation Center Research Report

One of the first published methods for the structural design of highway pavements was called the Massachusetts Rule and was presented in the eighth annual report of the Massachusetts Highway Commission in 1901 (1). The essence of this procedure was a rather intuitive assumption concerning the distribution of vertical pressures beneath a loaded area. For design purposes, this required the selection of a design load which, since failure was assumed to be catastrophic and not cumulative, could be taken as the largest load that could reasonably be anticipated during the design life of the pavement. The prediction of such a …

Economic Analysis Of Alternative Flood Control Measures, L. Douglas James, Thomas M. Rachford, James Ray Villines, Clyde R. Dempsey, James Norris Cline, Carlos Fix Miller

KWRRI Research Reports

Within the last few years, the growing realization that an effective flood control program must include non-structural measures (land use management and flood proofing) has resulted in Presidential Executive Order 11296 requiring Federal agencies to seek the optimum combination of structural and non-structural measures for flood control. The requirement has created a dilemma. No methodology is available for systematic evaluation of alternative combinations of structural and non-structural measures. Prospective procedures are too time consuming to be feasible under current financial and manpower limitations.

The only way out is to perform much of the planning process by digital computer. With this …

Bridge Paint Specifications, Proposed Revisions, James H. Havens

Kentucky Transportation Center Research Report

During the past several years, I have devoted considerable attention and study to bridge-paint systems and specification -- in an attempt to keep abreast with developments and current practices throughout the country. My first proposal (July 30, 1958; copy appended) was motivated by development of a then-new rust-inhibitive pigment suggested by National Lead Company. The pigment had shown considerable promise as a substitute for red lead and appeared in many respects to be superior to red lead -- on of which was economy.

Investigation Of Use Of Preformed, Compressed Neoprene Seals In Joints Of Concrete Bridge Decks, Dennis L. Willaman

Kentucky Transportation Center Research Report

Progressive deterioration and staining of concrete bridge substructures and erosion of abutments may, in many instances, be attributed to the leakage of bridge deck joints. The primary difficulty in maintaining a properly sealed joint is the continual expansion and contraction of the bridge spans. Joint seals, of course, must remain in contact with both faces of the disjointed sections and remain flexible at all temperatures encountered.

A study was initiated by the Division of Research for the specific purpose of evaluating the performance of preformed, compressed neoprene seals and to compare the performance of these seals with the performance of …

The Crab Orchard And Osgood Formations: The Case For Slope Instability, Robert C. Deen

Kentucky Transportation Center Research Report

For the past few years, the Division of Research, as a part of its continuing study of the occurrence of landslides in Kentucky, has reviewed and studied several sites in order to identify and delineate the geologic and soil formations which might be involved in the unstable earth masses. After a study of a number of landslides, it became evident that one particular material was highly susceptible to the development of landslides. This material, in Eastern Kentucky, is known as the Crab Orchard Formation and was deposited during the middle Silurian age. The Crab Orchard Formation, a deposit some 50 …

An Evaluation Of Temperature Distribution Within Asphalt Pavements And Its Relationship To Pavement Deflection, Herbert F. Southgate

Kentucky Transportation Center Research Report

The attached report presents significant progress and achievements in the area of asphalt pavement design. Benkelman beam deflections were used extensively in conjunction with our 1958 study of asphalt pavement performance; apparent relationships between 18–kip deflections and pavement structures were evident then although scatter in the data was thought to be necessarily admissible. During the spring and summer of 1966, another extensive series of pavements, built since 1958, were evaluated from the standpoint of performance and deflection. It seemed compelling at that time to adjust all deflections to some common reference temperature and so the surface temperature of the pavement …

Tobacco Bed Treatment With Enide 50w, J. W. Herron, J. F. Freeman

Agronomy Notes

Enide 50W is recommended for trial use on tobacco beds for 1968. The results of treatments with Enide in Kentucky in 1967 have been somewhat variable; therefor e, until additional information is obtained and the tobacco grower becomes more experienced in applying the chemical, it should be used on a trial basis.

Analysis Of Traffic Loads On Bridges, Robert L. Lynch

Kentucky Transportation Center Research Report

This report contains information concerning:

1. The statistical determination of frequencies of critical axle loadings on highway bridges and
2. The adaptability and adaptability of historical loadometer and classification data in Kentucky to the recently adopted AASHO design criteria for evaluating the fatigue history of existing bridges.

The analysis of the fatigue history of a bridge consists of evaluating the distribution of instantaneous axle loadings over the applicable period. Because of the urgency, only historical records currently available were used as source data. This report is therefore divided into two sections: 1) a summary of quantitative results based on available data, and …

Economic Analysis Of Flood Detention Storage By Digital Computer, James Ray Villines, L. Douglas James

KWRRI Research Reports

The objective of this study was to develop a digital computer procedure for preliminary analysis of the economic justification of reservoir detention storage for flood control and to present a sample study illustrating its application. A computer program called the University of Kentucky Flood Control Planning Program III was developed and tested on the flood plain of the South Fork of the Licking River in northeastern Kentucky.

Given a specified reservoir site and a downstream flood plain divided into planning units, Program III selects the economically efficient combination of reservoir detention storage and the associated combination of channel improvement, flood …

Control Annual Weeds In Tobacco Fields With Herbicides, J. F. Freeman

Agronomy Notes

In the years 1957 to 1967 inclusive, many promising herbicides have been used in Kentucky research trials for controlling annual weeds in tobacco fields. Burley tobacco has been used every year at Lexington, for 4 years at Eden Shale farm in Owen county, and 1 year in McCracken county, while dark air-cured tobacco was used for 4 years at the Western Kentucky Substation, Princeton.

Planning Flood Control Measures By Digital Computer, James Norris Cline, L. Douglas James

KWRRI Research Reports

The purpose of this study was to develop adequate guidelines whereby those interested in flood control planning would be able to apply a pair of digital computer programs known as the University of Kentucky Flood Control Planning Programs to ease the computational burden of evaluating specific flood control situations. Program II determines the economically optimum combination of channel improvement, land use restriction, and flood proofing for flood damage abatement. Program III also incorporates reservoir storage into the planning process. The Programs are not intended to provide a finished design but rather to select the optimum combination of flood control measures …

Grass Seed Production, Robert C. Buckner, Warren C. Thompson

Agronomy Notes

Producing cool season grass seed crops has historically been a profitable venture on Kentucky farms.

When growing maximum yields of grass seed, the pH level should be maintained between 6.0 and 7.0, when the recommended rates of limestone are used, and when phosphate and potash are maintained at medium-to-high levels (based on a soil test). Similarly, grass should be grown in pure stands. Weeds and insects must be controlled to prevent yield reduction.

Following seed harvest, excess herbage should be removed, preferably by grazing. All cool season grasses can be grazed until growth stops in the late fall or early …

Response Of Corn To Broadcast Applications Of Zinc, Harold F. Miller

Agronomy Notes

Where zinc deficiency in corn occurs on Kentucky soils it has been corrected by applying 3 to 6 pounds of elemental zinc per acre in the row at planting time. In some areas of the state, corn planters with row fertilizer attachments are not generally used, raising the question as to library the amount of zinc required when broadcast applications are made.

Through the cooperation of Clarence Mitchell, Area Extension Specialist, a field was located where the 1966 corn crop showed zinc deficiency. Since the field was to be planted in corn (Connecticut 860) in 1967, a field trial with …

Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock

KWRRI Research Reports

In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of …

Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …

Application Of Marginal Economic Analysis To Reservoir Recreation Planning, John Ellis Sirles Iii, L. Douglas James

KWRRI Research Reports

Recreation visitation and cost data at three reservoirs in the Ohio River Valley (Rough River, Dewey, and Winton Woods) were analyzed in an attempt to derive a method by which the optimum level of reservoir recreation development could be determined by marginal economic analysis.

The visitation data were used to determine factors expressing the time distribution of facility use, capacity coefficients, and realized benefits. The cost data were used to estimate annual cost, and marginal cost as functions of annual visitation. Marginal cost and marginal benefit data were combined to find the optimum size.

Potential visitation to Winton Woods was …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Esthetic And Recreational Potential Of Small Naturalistic Streams Near Urban Areas, John A. Dearinger, Kenneth R. Harper, L. Douglas James

KWRRI Research Reports

The purpose of this study was to find a way to evaluate the esthetic and recreational potential of small streams and their watersheds. Research was limited to naturalistic streams with drainage areas under 100 square miles and located within 25 miles of a city. A methodology, based on some previous work of the U.S. Soil Conservation Service and the principles or concepts of terrain analysis, land use planning, value Judgment philosophy and the economics of outdoor recreation, was developed and applied in detail to two streams (Boone and Jessamine Creeks) near Lexington, Kentucky.

Evaluations were made of the streams' potential …
