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 …

Hot-Mix Coal-Tar Concrete Pavement And Multiple, Coal-Tar Seals On Shoulders, Robert L. Florence

Kentucky Transportation Center Research Report

It is proposed to construct an experimental section of roadway, 6.6 miles in length, using coal-tar concrete for base and surface, and to use multiple, coal-tar seals (3 seals) with coverstone on the shoulders. A section of pavement, 5.1 miles in length, incorporating the same structural thicknesses and types of courses but containing normal asphaltic binders, to be constructed on the same route will be designated for comparison and control purposes. The use of the coal-tar will be in compliance with Section 201(e) of the Appalachian Regional Development Acts of 1965.

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 …

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 …

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 …

Construction And Interim Performance Report Of Experimental Salt (Nacl) Stabilization Of Plant-Mixed, Dense Graded Aggregate, Robert L. Florence

Kentucky Transportation Center Research Report

For some time the Department has been interested in building-up and retaining thicknesses of granular base course on rural roads through the use of various stabilizing additives and(or) the use of light asphalt seals or surfacings (1, 2, 3, 4, 5, 6). These efforts more or less recognize that the "stage construction" concept is frustrated by weather and traffic erosion of unbound and exposed granular base material. Thus, the motive in experimenting with and in utilizing these treatments is to find economical and effective means by which a granular base can be built and retained until such time that a …

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 …

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 …

Ecological Study Of The Effects Of Strip Mining On The Microbiology Of Streams, Ralph H. Weaver, Harry D. Nash

KWRRI Research Reports

The microflora of Cane Branch of Beaver Creek in McCreary County, Kentucky, which drains an area that was strip-mined between 1955 and 1959, was studied and compared with that of Helton Branch which drains a comparable area where there has been no mining. Differences include: the establishment of Ferrcbacillus ferrooxidans, for which procedures were developed for direct colony isolation from the stream; fewer saprophytic bacteria; more numerous and more diversified filamentous and unicellular fungi; and characteristic differences in algal flora. Representatives of 42 genera of filamentous fungi were identified. Of these, 21 were isolated only from Cane Branch. Representatives 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 …

Application Of Stanford Watershed Model Concepts To Predict Flood Peaks For Small Drainage Areas, K. D. Clarke

Kentucky Transportation Center Research Report

This report embodies two principal objectives: 1) updating rainfall intensity-duration curves for the hydraulic design of culverts and 2) adaptation of the Stanford Watershed Model concept to small drainage basins in Kentucky. The first objective is familiar -- the curves presently being used for the rational method of design were established from an earlier Department study made by E. M. West and W. H. Sammons, issued in July, 1955 (Report No. 2, "A Study of Runoff from Small Drainage Areas and the Openings in Attendant Drainage Structures"), and were based on rainfall records then available through 1951. The second objective …

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 …
