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 …

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 …

Establishment And Maintenance Of Roadside Plantings And Turf, K. C. Arnold, J. T. Griffin

Kentucky Transportation Center Research Report

The suitability and choice of different plant materials for roadside planting will be governed primarily by cost of establishment and maintenance, by the effectiveness in stabilizing the soil, and by safety and beauty achieved. It must be recognized that conditions often encountered in roadside planting situations are different from normal conditions found in fields and yards. Soils often consist of unclassified material and are not agricultural soils in the usual sense. The material usually contains very little if any humus and little plant food and often is highly susceptible to erosion. Under these extreme conditions the establishment and maintenance of …

Flow Behavior Of Asphalt Cements, W. A. Mossbarger Jr., John A. Deacon

Kentucky Transportation Center Research Report

The Kentucky Department of Highways in cooperation with the Bureau of Public Roads is conducting a continuing investigation of the fundamental mechanical properties of flexible pavement materials. The ultimate objective of this investigation is to gain sufficient knowledge of the fundamental mechanical behavior of these materials to support the establishment of a responsive flexible pavement design procedure.

A preliminary report, issued in 1964, contained the results of the preparatory phase of this investigation. This report summarized from a theoretical point of view efforts that had been made to quantify the mechanical response of viscoelastic materials to known conditions of loading. …

Unit Weights Of Paving Materials, For Estimating Quantities, James H. Havens

Kentucky Transportation Center Research Report

Pursuant to our assignment, continuation issuing from the meeting of March 29, 1967, with Messers Brunnhoeffer, Mathis, et al, the Research Division staff performed specific-gravity tests on an ensemble of gravel samples furnished by Mr. Mays and made further evaluations of those and other data available -- that is, for the purpose of deriving the best or most judicious unit weights -- with a minimum of areal and mineralogical differentiation. Because of previously recognized variances in pavement densities, we elected to proceed on a theoretical basis. On the basis of assumed volume constants, it was possible to calculate theoretical unit …

Economic Impacts Of The Highway Beautification Act In Kentucky, Vincent W. Mcgurl

Kentucky Transportation Center Research Report

The Highway Beautification Act of 1965, Public Law 89-285, has as one of its main purposes "the control of outdoor advertising along interstate and all Federally aided primary highways "in order to protect "the public investment in such highways, to promote the safety and recreational value of public travel and "to preserve natural beauty." The Secretary of Commerce, in cooperation with the state highway departments, was authorized to make a comprehensive study of the economic impact of such legislation on affected individuals and commercial and industrial enterprises.

Research Relating To State Highway Laws, James H. Havens

Kentucky Transportation Center Research Report

The Department's study began late in 1962 and was undertaken as a review and analysis of the main body of highway law; but, of course, any subsequential objectives--stated or implied-remained contingent upon and would become a natural consequence of the first-mentioned type of inquiry and the improbablity of discovery. Undoubtedly, the Department was influenced by and was under inducement of the Bureau of Public Roads in this undertaking, The review-and-analysis phase was accomplished, in part, by the School of Law, University of Louisville, acting under contract (CH119 36, dated November 15, 1962) which was subsequently dissolved (9-30-63); a draft report …

Highway Construction In Windblown Silts Of Western Kentucky, Robert C. Deen

Kentucky Transportation Center Research Report

It has been shown that engineering experience and performance histories of earthwork structures and foundations in distinctive physiographic regions provide valuable insights applicable to the planning and construction of future projects. Geologic information further categorizes earth materials on the basis of parent material and geologic processes which modify the rock and soil masses. A knowledge of the resulting topographic expression or landforms and reference to geologic and soils information contained in surveys, reports, and maps is particularly useful in the early stages of planning and site selection. When sufficient information is available, regional units may be recognized for the purpose …

Skid Testing With An Automobile, Rolands L. Rizenbergs, Hugh A. Ward

Kentucky Transportation Center Research Report

A study was conducted to evaluate the theoretical and practical aspects of using an automobile as a testing device for measurement of pavement slipperiness. Every parameter and significant event in the excursion history of a skidding automobile was measured and recorded. The resultant skid-resistance values, twenty-five in all, were compared and correlated. As a result of the study, the measurement of time in the velocity increment between 30 mph to 20 mph was selected as an interim standard test. A number of experiments were also conducted to aid in the interpretation of test results and to establish control tolerances for …
