17-Year Report On The Owensboro-Hartford Co-Operative Investigation Of Joint Spacing In Concrete Pavements, Milton Evans Jr., William B. Drake

Kentucky Transportation Center Research Report

In 1940, the Kentucky Department of Highways constructed an experimental concrete pavement which was one of a group of six built in co-operation with the Bureau of Public Roads by the States of Minnesota, California, Kentucky, Michigan, Missouri and Oregon. The purpose of these projects was to study and evaluate the performance of such pavements over a period of years with specific regard to types of joints and spacings. The Kentucky project, consisting of 6.27 miles, was constructed in Daviess County, beginning approximately 6 miles south of Owensboro on US Route 231 (formerly Ky. Route 71).

Re-Evaluation Of The Kentucky Flexible Pavement Design Criterion, William B. Drake, James H. Havens

Kentucky Transportation Center Research Report

Prior to 1948, the criterion in Kentucky for designing the thickness of bituminous pavements was based upon a modified laboratory CBR and the 1942 curves developed by the California Department of Highways. In 1948, the Materials Research Laboratory reported: "An Investigation of Field and Laboratory Methods for Evaluating Sub-grade Support in the Design of Highway Flexible Pavement." Included in that report as a recommended method of thickness design for use in Kentucky was a set of curves based upon an empirical relationship between minimum laboratory CBR and observed pavement performance. These five curves accounted for traffic groups up to 10,000,000 …

Bridge Resurfacing With Silica Sand-Asphalt Mixture, Loren H. Strunk

Kentucky Transportation Center Research Report

The bituminous section has been engaged in testing silica sand-asphalt mixtures composed of various penetration grades of asphalt and sands from sand and sandstone deposits from several different areas of the state since early this year. The purpose of this study was to develop a surfacing mixture which would provide a skid-resistant surface and which could be machine laid in thin courses.

Skid Prevention Studies In Kentucky, James H. Havens

Kentucky Transportation Center Research Report

Laboratory apparatus, consisting essentially of a torque generator and a torque meter, in which a rubber annulus is driven against a plane surface of a rock core or pavement specimen, as in an ordinary friction clutch, was used to study variations in the coefficients of friction with respect to texture and material characteristics. Dry friction coefficients were found to be rather high in magnitude. and fairly constant throughout wide variations in surface textures. In contrast, wet friction coefficients were very high for rough textures but very low for polished surfaces. Wet friction values correlated in an approximately hyperbolic manner with …

Differential Thermal Analysis Of The Freeze-Thaw Mechanisms In Concrete, James H. Havens, Knox R. Burchett

Kentucky Transportation Center Research Report

The freezing of water in concrete may create highly disruptive internal forces, depending upon the degree of saturation of the voids and the extent of the resulting dilations. Heretofore, it has not been possible to measure the internal pressures accompanying freezing; and it is this aspect of the automatic freeze-thaw testing of concrete with which the present study was concerned. By the use of thermocouples, imbedded in concrete and referenced to an ice-water bath, it was possible to plot, on an automatic multivolt potentiometer recorder, an isothermal phase change for the absorbed water, and to demonstrate a depression of the …

This system shall consist of a primer-, intermediate-, and finish-coat paint as hereafter specified. Uses of the component paints other than as an integral part of this system are specifically excluded.

An Evaluation And Summary Of The 16-Year Performance Of A Concrete Test Pavement, Milton Evans Jr.

Kentucky Transportation Center Research Report

Presented herein are a summary and evaluation of the performance of a reinforced concrete section of U.S. 27 in north central Kentucky which has been in existence since the summer of 1941. The pavement, totaling 7.89 miles, was constructed in 10 experimental test sections, as shown on the layout map in Figure 1. Five blends of cement, containing normal portland, natural, and two additives, were used with two types of coarse aggregate, limestone and gravel. Since the construction of the pavement in the summer of 1941, several reports and memoranda have been released dealing with various aspects of the over-all …

A Study Of The Use Of A Local Fly Ash In Concrete Mixes, Frank D. Whitney

Kentucky Transportation Center Research Report

The widespread use of powdered coal in industrial furnaces has, since its introduction in the 1930's, produced considerable increases in efficiency for many industrial processes. In its wake, however, it has brought its own unique problems, and chief among these has been the problem of collecting and disposing of the residue which results from the combustion of the powdered or ground coal. This residue, known commonly as fly ash, is a nuisance if it is allowed to be dispersed into the atmosphere; and if collected it presents a difficult disposal problem. In present industrial practice it is almost always collected, …

A Study Of Lime And Fly Ash With Regard To Soil Stabilization, James F. Hardymon

Kentucky Transportation Center Research Report

The paving of roadways originally developed from the inadequacy of natural soils to support vehicles and pedestrian traffic. Thus a pavement serves as a nearly rigid covering which distributes otherwise highly concentrated surface loads over wider areas of the underlying soils, Most natural soils are deficient for direct roadway service unless such a covering is provided or unless the soil itself is solidified, concreted, or otherwise reinforced, Attempts to compensate soils for these inadequacies in order to minimize the thickness of pavement needed have developed into a specialized aspect of highway design and construction known as soil stabilization.

Comparative Laboratory Evaluation And Field Observations Of A Modified Class I Base, Loren H. Strunk

Kentucky Transportation Center Research Report

A number of materials and methods have been used in the continuing search for a satisfactory initial bituminous treatment. Towards this end, three traffic bound roads were given initial treatment, in the summer of 1956, with three inches of Kentucky a Standard Class I Base mixture. The large size coarse aggregate -- either No. 36 or No. 48 stone -- in this mixture made the material difficult to work, however, and caused severe segregation during handling. Although a well integrated mixture of the type could have been compacted to about eight percent voids, the excessive segregation left many areas of …

An Engineering Soil Survey Of Fayette County, Kentucky, Robert C. Deen

Kentucky Transportation Center Research Report

The need for soils data in the site selection, design, construction and maintenance of any major structure is generally appreciated by the engineer. The "rule of thumb" methods often used in developing smaller structures can prove unsatisfactory, or even disastrous, when applied to larger projects.

A Study Of The Polishing Characteristics Of Limestone And Sandstone Aggregates In Regard To Pavement Slipperiness, William J. Stutzenberger, James H. Havens

Kentucky Transportation Center Research Report

The coefficient of friction on dry highway surfaces regardless of stone composition and texture has in most cases been at least 0.6 or above. However, some of these same surfaces when lubricated by a small amount of water have given test results dangerously lower. Some interesting theoretical aspects of this situation are presented here along with results from a laboratory study of the fundamental factors affecting tractive friction.

A machine is described for measuring the coefficient of friction between the plane surfaces of four-inch diameter stone specimens and a rubber annulus of slightly smaller diameter. Measurements were made both wet …

Location And Economic Study For Interstate Route Tallahassee, Wilbur Smith And Associates

City and Regional Planning -- Florida

The basic purpose of the study was to determine the best location for the construction of an East-West section of the interstate highway. It was prescribed that the work would consist of two basic parts. One had to do with the analysis of travel data, both present and projected, in the determination of the most feasible location of a route based on conventional traffic and highway development factors. The other phase of the work was to deal with economic considerations, especially the economic impact of the proposed routes on businesses located on existing roads and on the central business district …

Ten Rural Highway Base Stabilization Projects, James H. Havens, William B. Drake

Kentucky Transportation Center Research Report

During the last week o£ September, 1956, the Division of Rural Highways requested assistance from the Research Division in conducting a series of ten experimental base stabilization projects which were to be geared more-or-less to a practical rural roads development program in which existing soils and local granular materials might be most advantageously treated and stabilized to provide fairly low cost base courses and surfaces, adequate for light rural traffic. The idea of actually constructing a base and bituminous surface for this type of road would represent a refinement over the traditional traffic-bound base type of construction which usually serves …
