Shape Factors For Conduction Of Heat, Harry J. Otway

Mechanical Engineering ETDs

The purpose was to measure the heat conduction shape factors for cylinders and square prisms enclosed by spheres and to estimate the accuracy of the following approximation. This approximation is that of matching the area of the cylinder or prism to an equivalent sphere and then applying the analytical solution for concentric spheres.

A Radar Refraction Correction For Symmetric And Nonsymmetric Tropospheric Index Distributions, Ralph J. Rainey Jr.

Electrical and Computer Engineering ETDs

The high precision radars now in use have demonstrated the need for more exact refraction correction than is afforded by any fixed "standard" refractive index profile. The precision capabilities are even substantial enough to cause concern over the possible effects of the non-symmetric index distribution which introduces azimuthal errors. However, the indications are that the present limitation on true range measurements are primarily due to limitations on the radar itself, and a "gross" average correction is adequate for many cases of interest.

Performance Report On Bridge Resurfacings With Silica Sand-Asphalt Mixture, Robert L. Florence

Kentucky Transportation Center Research Report

When the Maintenance Division found it necessary to resurface the Clark Memorial and Ashland-Coal Grove Bridges in 1958, a thin, silica sand-asphalt, wearing surface was recommended by the Research Division. The basis of the recommendations was the promising results obtained in laboratory testing and the apparently successful resurfacing of bridges with thin applications of silica sand-asphalt in the New York Area and elsewhere. The design and construction details pertaining to these two projects have been reported previously. This report is a record of the performance of the two projects and of the repair of spalled areas on the deck of …

Analysis Of Pavement Roughness, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

In earlier progress reports dealing with the development of triaxial acceleration analysis as applied to the evaluation of pavement riding qualities, of which this report is a continuation, riding comfort or discomfort was emphasized. The accelerations monitored then were evaluated in terms of g's per sec., or "jerk" which is considered by some authorities to be a more significant index of comfort. The earlier methods of analysis have been reviewed, and acceleration is considered here to be the most practical parameter to use as a measure of pavement roughness. Most of the equipment and instrumentation has been retained, and the …

Proposed Special Specification For Sand Asphalt, Skid-Resistant, Wearing Course, James H. Havens

Kentucky Transportation Center Research Report

Because of the prominence that natural, sandstone, rock asphalt enjoyed in Kentucky during the past 50 years, sand-asphalts and sheet-asphalt mixes have not been used very extensively for paving in Kentucky. This is somewhat unfortunate because the natural, sand stone, rock asphalt has not been available since about 1955 and because there is now a need for a fine-textured, skid-resistance, wearing course for resurfacing work as well as on new pavements. These circumstances, coupled with the realization (1953-54) that surface courses and chip seals using 100% limestone aggregates tend to become slick, have emphasized the need for specifications for sand-asphalts. …

A Method For The Design Of Foundations Supporting Highway Signs, Robert C. Deen

Kentucky Transportation Center Research Report

With the increased mileage of highways being built to high standards, the resulting high-speed travel requires that more and larger signs be installed to relay to the motoring public information they require. It would be desirable to have a method of design which will result in a foundation involving rather simple construction procedures. It was decided that a cylindrical, non-reinforced concrete foundation with an uniform diameter would be the most advantageous for construction purposes. It should be realized, however, tha(the most efficient shape theoretically is one that has increased diameters at the top and the bottom.

Experimental Paving Projects Using Curtiss-Wright’S Coal-Modified, Coal-Tar Binder (First Year Performance), James F. Hardymon

Kentucky Transportation Center Research Report

This report has been prepared as a sequence to the author's publication entitled, "Experimental Paving Projects using Curtiss-Wright's Coal-Modified, Coal-Tar Binder (Construction Phase)."

The previous study was concerned with the selection of test sites, the construction of the test and control sections, and the laboratory investigation performed before and d uring the construction period. This project started in April, 1959, when the Curtiss-Wright Corporation announced the development of a new and superior road-paving binder utilizing bituminous coal. The development was the result of their research program conducted in an effort to find new uses for coal and coal products.

Performance Survey Of Reinforced Concrete Pipe Culverts, Robert C. Deen, Ronald D. Hughes

Kentucky Transportation Center Research Report

Methods of installation and design criteria have tended to restrict the usefulness of rigid pipe culverts. With the increased mileage of highways which meet high standards, there has been an increase in the number of pipe culverts installed under high fills. This, of course, has accented the need for criteria for the proper design and installation of rigid pipe to obtain the maximum utilization of the pipe strength and to minimize the possible steelements that may occur in the road surface near the pipe installation or in the flow line of the pipe culvert.

In order to provide for an …
