Application Of The Hveem Stabilometer To The Testing Of Open-Graded Bituminous Mixtures, R. A. Hannan

JTRP Technical Reports

This laboratory investigation was conducted with the purposeof determining the applicability of the Hveem Stabilometer to the testing of open-graded bituminous mixtures.

The study was divided into two major sections. The first of these investigated the validity of the Stabilometer displacement measurement when applied to open-graded specimens having large surface air voids. The second portion of the study had two specific purposes: (l) to investigate the stress-strain characteristics of open-graded mixturestested in the Hveem Stabilometer and (2) to determine whether surface voids on the ends of Stabilometer test specimens influenced Hveem stability values.

To check the validity of the displacement …

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.

An Investigation Of High-Strength, Deformed Steel Bars For Concrete Reinforcement Part Ii, Sidney A. Guralnick, George Winter

CCFSS Library (1939 - present)

INTRODUCTION The previous phase of this investigation of high-strength steel for concrete reinforcement is described in Report No. TSR-4730-7l46, which was released in July, 1957. This previous testing program was designed to provide information on the following topics, among others: (a) The shear (primarily) and flexural (secondarily) strength of restrained Tee-beams reinforced with steel of approximately 80 ksi yield point for main reinforcement and with standard steel for web reinforcement. (b) The formation of diagonal tension cracks and flexural cracks and the width of flexure and shear cracks at various loads and particularly at "design loads" (say, half the ultimate …

The Importance Of Hydraulics Of Surface Irrigation, Vaughn E. Hansen

Reports

Summary: Surface irrigation is a complex hydraulic phenomenon. The hydraulic elements involved in surface irrigation are listed and discussed. Relating these hydraulic elements is the key to efficient irrigation, good design, and permanent agriculture.

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 …

A Design Of Los Esteros Flood Control Dam, Constantine G. Hadjidakis

Civil Engineering ETDs

This thesis covers a preliminary design of the Los Esteros Dam based on limited subsurface investigations and laboratory testing. This earth-filled dam will be 222 feet high and will have a top width of 20 feet.

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 …

Recommendations For Special Specifications, Covering Basic Lead Silico-Chromate, Oil-Alkyd, Vinyl-Alkyd Paints For Bridges, James H. Havens

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 …

Construction Of A Heavy Duty Military Airfield On Permafrost., Owen N. O'Leary

Civil Engineering ETDs

An examination of the map of the northern hemisphere will show that the two great population areas of opposing ideologies are located across the arctic regions from each other. This fact has been recognized by the U.S. military authorities since the early 1940’s, and an effort has been made to locate military forces in these regions to act as a possible deterrent to any aggressive action. The nature and geography of this region generally preclude any military forces except combat airfield. The most outstanding and possible only example of a major military airfield located entirely on permafrost material in these …

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.
