Kentucky Transportation Center Research Report

This specification covers the material requirements for a Basic Lead Silico-Chromate, Oil-Alkyd Paint System intended for use on exterior iron and steel structures (bridges), for either new or re-paint work, except where exposed to severely corrosive conditions such as within the splash-zone from bridge decks or on other members likely to be affected by de-icing salts or persistent moisture conditions. 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 …

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 …

A Survey Inspection Of Plain Corrugated Metal Pipe Arches And Multi-Plate Metal Pipe Arches In Kentucky, Eugene M. West

Kentucky Transportation Center Research Report

Past observations have indicated that rusting has been rather prevalent in the large, un-paved metal drainage structures most of which have been installed since the opening of the Kentucky Rural Secondary Program in 1949. Since all of these structures are relatively new, and since rusting in any form can be considered a threat to the life of a structure, the Chief Engineer's Office, in 1954, requested that a study be made to determine the over-all frequency possible causes, and individual seriousness of this condition.

Altogether, a total of 86 of these un-paved structures were inspected. Although it would have been …

Hydraulic Model Studies Of Culvert Operation, Eugene M. West

Kentucky Transportation Center Research Report

Since 1951 the Division of Research has been engaged in a comprehensive study of highway drainage problems. This study has included special investigations of rainfall and runoff, drainage structures in use and the practices used in their design, culvert hydraulics, and other relevant investigations. To date, reports have been published concerning runoff and rainfall variables (1 and 2)* and the effects of barrel roughness upon culvert operation (3), together with the preparation of a drainage manual for the use of Highway Department engineers and consultants.

The most recent special project, part of the over-all study, has dealt with the effects …

Analysis Of Pavement Riding Quality: A Triaxial Evaluation Of Pavement Roughness, William S. Foy

Kentucky Transportation Center Research Report

For the last twenty-five years considerable research has been directed toward developing reliable equipment for evaluating pavement roughness. Since roughness inhibits passenger riding comfort and safety, as well as inducing vehicle deterioration, the determination of the features that cause roughness would indicate possible improvements in pavement design, materials, construction practices and equipment. For example, certain types of base design might be found to produce smoother surfaces than others; and a construction practice such as a blade-spread leveling course might result in more uniform pavements. Then too, evaluation of pavement roughness would permit relative comparison of pavements as one of several …

A Field And Laboratory Examination Of Weathering Effects On Petroleum And Blended Petroleum-Natural Asphalts In Paving Mixtures, Ellis G. Williams

Kentucky Transportation Center Research Report

The relative merits of various asphalts and asphaltic materials have been the subject of considerable controversy almost from the beginning of flexible pavement construction in this country. In this early period petroleum asphalt had not yet entered the picture and controversy centered about naturally occurring products such as Trinidad natural asphalt and impregnated stones. In 1876 Congress directed that comparative service tests be made on a rock asphalt* and a sheet asphalt containing Trinidad natural asphalt. The sheet asphalt was considered the more successful of these and thus Trinidad natural asphalt became firmly established as a paving material in this …
