Traffic Controls For Maintenance On High Speed Highways, William M. Seymour

Kentucky Transportation Center Research Report

Observations were first made at lane closures on interstate highways where yellow warning signs were erected routinely in conjunction with contract work. Later data provided direct comparison between new yellow and new orange signs. One sign scheme was used throughout the study. Driver obedience improved when new signs of either color were used; this finding implies that signs should always be maintained in good condition. Orange signs were slightly more effective than yellow signs in reducing traffic conflicts and merges near the traffic cones. The results of the study tend to support the adoption of orange as the standard color …

Expansive Limestone Aggregate In A Concrete Pavement, James H. Havens, Assaf S. Rahal

Kentucky Transportation Center Research Report

Recurrent blowups and surface cracking are common symptoms of distress in concrete pavements. Premature appearance of distress symptoms is alarming because the materials used in the concrete become suspect. Criteria for design, quality of materials, and construction are necessarily re-evaluated. Indeed, a dutiful effort to discover the cause(s) and to provide future safeguards is reasonably expected.

The analysis of causative factors besetting I 65-1(13)13 was complicated by an intuitive notion that blowups and surface cracks might be separate and independent problems. The crack pattern resembled the configuration of the wire mesh -- which was vibrated into position after the concrete …

Comparison Of Ammonium Nitrate And Urea As Nitrogen Source For Topdressing Established Grass Sods, Grant Thomas, Harold F. Miller

Agronomy Notes

When urea is broadcast and not worked into the soil there is a risk of some of the nitrogen being lost to the atmosphere as ammonia. In an effort to measure the effectiveness of urea compared to ammonium nitrate as sources of nitrogen for topdressing on established grass sod, an experiment comparing these two sources at rates to supply 0, 50, 100 and 150 pounds of nitrogen per acre was conducted in 1971.

Digital Computer Modeling Of Limestone Groundwater Systems, John Thrailkill, David P. Beiter

KWRRI Research Reports

Because limestone groundwater flows mainly In discrete openings, limestone aquifers are fundamentally different from aquifers In granular rocks. A digital computer program which simulates flow in a limestone aquifer as a pipe network was written and compared with the Sinkhole Plain aquifer of west-central Kentucky.

A reasonably good fit between observed parameters of the aquifer and those calculated were obtained under assumed conditions of both laminar and turbulent now In the aquifer. The Indicated gross permeablllty of the aquifer is 5600 melnzers with an assumed aquifer thickness of 100 feet. The location and discharge of springs along the streams bounding …

From Caveat Emptor To Strict Liability: A Review Of Products Liability In Florida, Richard C. Ausness

Law Faculty Scholarly Articles

Since the doctrine of caveat emptor gave way to a more enlightened response, the courts have struggled to place the law of products liability on a proper doctrinal foundation. Negligence, implied warranty, and strict liability have been used, but as yet no universally accepted theory has emerged. In light of this problem this article will trace the development of seller's liability in Florida. Special emphasis will be placed upon implied warranty; in addition, the relationship between existing Florida case law, strict liability under the Restatement of Torts and the warranty provisions of the Uniform Commercial Code will be examined.

An Operational Analysis Of The I 64, I 65, I 71 Route Junction In Louisville, Jerry G. Pigman, William M. Seymour, Kenneth R. Agent, Don L. Cornette

Kentucky Transportation Center Research Report

The Kennedy Interchange in Louisville is the most geometrically complicated of any in Kentucky; it is the junction of three interstate routes, I 64, I 65, and I 71. The many diverging, weaving, and merging movements demand a driver's attention. One merging situation collapses into an impasse during peak-hour traffic. This study is responsive to certain inquiries by the Department concerning safety and possible discovery of design deficiencies at this interchange. It was not intended to be an in-depth study but rather an exploratory identification of problems and their locations; more comprehensive studies, by others, would ensue if needed. The …

Comparative Evaluation Of Raygo 404 Vibratory Roller, Jerry D. Ross, Herbert F. Southgate, Donald C. Newberry Jr.

Kentucky Transportation Center Research Report

Roller evaluations are rather phenomenological -- that is, one must rely somewhat on observations. Density measurements following each excursion of the compactor may not relate directly to the work done in compressing the layer. When no increase in density is realized, no work is accomplished. Work is defined here in the classical sense. Energy expended without producing an increase in density is wasted. Thereafter, the only way additional classical work can be done on the layer is to reduce density.

The number of excursions necessary to achieve an acceptable or comparable density generally reflects efficiency of the compactor. Much may …
