Energy In Agriculture: Performance Evaluation For Natural Air And Low-Temperature Drying Systems, Otto J. Loewer, Thomas C. Bridges, G. M. White, Robert L. Fehr, Larry W. Turner

Agricultural Engineering Energy Series

Natural air and low-temperature drying systems are generally not recommended for Kentucky because of their slow drying rates. In such systems the grain near the top of the drying bin may remain undried for an extended period of time, possibly leading to grain spoilage and/or the production of aflatoxin.

Energy In The Home: Grain Drying Performance Evaluation, Otto J. Loewer, Thomas C. Bridges, G. M. White, Robert L. Fehr

Agricultural Engineering Energy Series

When grain is harvested in Kentucky at moisture contents exceeding 13 to 14 percent, it must be dried to insure long-term safe storage. The drier the stored grain, the longer it will retain its quality.

Influence Of Nitrogen Fertilization On The Quality And Quantity Of Streamflow From A Forested Watershed, George B. Coltharp, Michael T. Shearer, Everett P. Springer, Robert F. Wittwer

KWRRI Research Reports

This project was designed to determine the effects of nitrogen fertilization on the quality and quantity of streamflow eminating from an eastern hardwood forest watershed. A 40.67 ha watershed, located in mountainous eastern Kentucky, was aerially fertilized in late April 1975. The forest stand was principally oak, hickory, and yellow poplar, 50 - 55 years of age and in a relatively undisturbed condition. A helicopter applied anunonium nitrate at a rate of 504 kg/ha. Because a large part of applied nitrogen fertilizer ends up in the highly mobile nitrate nitrogen.form, this is the principal ion monitored in this study. No …

Warrants For Left-Turn Signal Phasing, Kenneth R. Agent, Robert C. Deen

Kentucky Transportation Center Research Report

Warrants for the installation of left-turn phasing were developed. A review of literature was conducted along with a survey of the policies of other states. Field data of delays and conflicts were taken before and after installation of exclusive left-turn signalization. Left-turn delay studies were conducted at intersections with varying volume conditions. Analysis of the effect on accidents of adding a left-turn phase was made. The relationship between left-turn accidents and conflicts was investigated. Other types of analyses concerning gap acceptance, capacity, and benefit-cost ratios were also performed.

It was found that exclusive left-turn phasing significantly reduced left-turn accidents and …

A Rational Thickness Design System For Asphaltic Concrete Overlays, Herbert F. Southgate, Gary W. Sharpe, Robert C. Deen

Kentucky Transportation Center Research Report

A method of designing asphaltic concrete overlays has been developed making use of (1) Kentucky's proposed design curves, (2) an estimate of future traffic and the associated fatigue (five procedures are presented according to types of information available), (3) strength of subgrade on subject project (laboratory CBR tests or results of dynamic in-place tests such as the Road Rater), and (4) present condition of the existing pavement (from dynamic in-place tests, roughness measurements, or present serviceability index). Deterioration was expressed as reduced thicknesses of new-quality materials producing the same measured dynamic deflections. The total thickness for the predicted traffic minus …

Simulation Of Travel Patterns For Small Urban Areas, Jerry G. Pigman, Robert C. Deen

Kentucky Transportation Center Research Report

The objective of this study was to develop models which would simulate internal-external trips and external-external (through) trips. Regression analysis and cross-classification of data were tested in an attempt to predict the number of internal-external trips and the percentage of through trips. Regression analysis was used in the development of a through-trip distribution model. Grouping data for analysis created some problems; however, trial-and-error evaluation enabled selection of variables which produced reasonable results. Variables found to be most significant in the development of internal-external models were population and employment. For through-trip models, variables used were population, functional classification, AADT at the …

A Proposed Revision Of Kentucky's Water Rights Legislation, Richard Ausness

KWRRI Research Reports

Kentucky's present system of water law consists of a statutory water withdrawal permit system superimposed upon a body of common-law water rights doctrine. The rights of water users are often uncertain under this system, particularly in periods of water shortage. The proposed revision of Kentucky's existing water rights legislation, would greatly reduce the significance of common-law water rights and would remedy some of the weaknesses in the present statute.

Part 1 of the proposed statute establishes an administrative structure; Part 2 deals with water withdrawal permits; Part 3 retains the present statute's provisions on the regulation of dams and impoundments, …

Energy In Agriculture: Energy For Swine Facilities Part Ii: Alternative Sources Of Energy, Robert L. Fehr

Agricultural Engineering Energy Series

Recently, there has been some concern about energy utilization in agricultural production. Shortages of natural and LP gas have affected many livestock producers, especially swine producers utilizing LP gas as a supplemental heat source in farrowing facilities. These shortages, coupled with an ever-increasing price for fuel and electricity, have encouraged many producers to begin looking for alternative energy sources.

Green-Extension Systems At High-Speed Intersections [Sept. 1978], Charles V. Zegeer, Robert C. Deen

Kentucky Transportation Center Research Report

The purpose of this study was to determine the effectiveness of green-extension systems (GES) for reducing the dilemma-zone problem associated with the amber phase of traffic signals at high-speed intersections. Reactions of 2,100 drivers were noted during the amber phase at nine intersections, and the dilemma-zone distances with respect to the stop bar were determined.

Before-and-after studies made at three green-extension sites showed a 54-percent reduction in total accidents and a 75-percent reduction in rear-end accidents after GES installation. Accident severity was unaffected.

Conflict, volume, delay, and speed data were taken before and after GES installation at two sites. A …

Evaluation Of Paint Stripe Beads, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

This report presents another phase of a study on evaluation of paint stripes and glass beads. The results from the previous phases of this study indicated that large-scale, experimental evaluation of a 1.65 refractive-index bead and a large-gradation, 1.52 refractive-index bead was warranted. Poor embedment of beads, however, precluded the evaluation because the quick-drying paint used did not allow beads to be properly embedded. After progressive thinning of the paint with solvent, adequate bead embedment was obtained. Drying time, of course, was longer.

Attempts were made to obtain good embedment without extending the drying time. This included testing of a …

Energy In Agriculture: Fan Performance On Grain Drying Bins, Otto J. Loewer, Thomas C. Bridges, G. M. White, Robert L. Fehr, Larry W. Turner

Agricultural Engineering Energy Series

One of the keys to successful in·bin grain drying and aeration is the matching of a drying or aeration fan to the drying or storage bin. A properly designed system will be more efficient in terms of both drying and energy utilization. The quantity of air that may be delivered through the grain depends upon grain type, bin size, fan type, fan horsepower, depth of grain, percent of foreign material and the extent to which the grain is packed.

Pavement Evaluation Using Road Rater Deflections, Gary W. Sharpe, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

Dynamic test deflections have been duplicated by elastic theory using the Chevron N-layered computer program. Dynamic surface deflections obtained using the Road Rater have been used in conjunction with elastic theory to analyze pavement behavior. A procedure has been developed to use field measured Road Rater deflections to estimate the elastic moduli of the foundation material and to determine the equivalent thicknesses of new material which approximate the behavior of the structure. The estimated moduli and (or) equivalent thicknesses may be used as inputs to design overlay thicknesses. An analysis of the deflections of the first three sensors of the …

Determination Of Rutting In Asphaltic Concrete Pavements: Field Instrumentation And Laboratory Characterizations, David L. Allen

Kentucky Transportation Center Research Report

This report describes a number of gages developed to measure the location and magnitude of ruts. These were installed in a newly constructed asphaltic concrete pavement. They measure lateral deflections and transient and permanent vertical deflections. Some preliminary vertical deflections are reported. An investigation of materials is also reported. The asphalt concrete base, dense-graded aggregate base, and subgrade material were characterized by (1) shear strength (triaxial tests), (2) rheologic behavior (creep tests), (3) permanent deformation characteristics (repeated-load and creep tests), (4) Young's modulus (resonant column tests), and (5) resilient properties (repeated-load tests). Empirical functions were formulated to describe the permanent …

Seasonal Variations In The Skid Resistance Of Pavements In Kentucky, James L. Burchett

Kentucky Transportation Center Research Report

Frequent measurements of skid resistance were made on 20 pavements in common use in Kentucky. Tests were conducted from November 1969 through 1973. Principal analysis involved relating changes in skid resistance to day of the year and relating skid resistance to temperature at the time of test, to average antecedent temperatures, and to average rainfall.

Seasonal variations exhibited an annual, sinusoidal cycle. The changes in sand-asphalt and bituminous concrete under higher volumes of traffic were about 12 skid numbers. The changes in portland cement concrete and bituminous concrete under lower volumes of traffic were about 5 skid numbers. The lowest …
