Energy Fact Sheet: Residential Solar Heating, Blaine F. Parker, Larry W. Turner
Energy Fact Sheet: Residential Solar Heating, Blaine F. Parker, Larry W. Turner
Agricultural Engineering Energy Series
Heating a residence and the domestic water supply with solar energy is technically feasible in Kentucky. However, it is not feasible to provide 100 percent of the heat requirements. Some backup system is needed for continuous heat during cloudy weather and the cold part of winter. Both passive and active solar heating systems are technically feasible.
Low-Void Concrete Mixtures, Assaf S. Rahal, James H. Havens
Low-Void Concrete Mixtures, Assaf S. Rahal, James H. Havens
Kentucky Transportation Center Research Report
The purpose of this study was to modify concrete mix-design formulas to supplant all water over and above that needed for hydration with a non-evaporable liquid material and(or) a super-water-reducer or plasticizer -- thus producing a low-void concrete. A water-cement ratio of 0.244 - 0.30 was presumed minimal for hydration of the cement. Several polymeric materials, asphalts, oils, and superplasticizers were used. Success was achieved with two latexes, one epoxy, and several superplasticizers. The use of these materials in concrete resulted in improved strength, reduction of air voids and permeability, and enhancement of resistance to corrosive chloride salts.
Acoustic Emission Monitoring Of Weldments, Theodore Hopwood Ii, James H. Havens
Acoustic Emission Monitoring Of Weldments, Theodore Hopwood Ii, James H. Havens
Kentucky Transportation Center Research Report
Weld tests were performed on low-carbon and high-strength, low-alloy steel weldments. The weldments were monitored with an acoustic emission detector during both the 'in-process' and the 'in-cooling' phases of the welding operation. Artificial defects were induced in several of the welds to promote cracking. Some high-strength weldments were designed to produce welds subject to high restraint.
Nondestructive and destructive evaluation of the completed weldments revealed that high acoustic emission activity 'in-cooling' could be correlated with embedded defects and cold-cracking. Copious emission activity was also detected from unflawed weldments. Acoustic emissions were detected in high-strength steel weldments for periods up to …

Energy In Agriculture: Grassland Renovation--Conserves Oil And Energy And Increases Returns From Grass Fields, Edward M. Smith, Larry W. Turner
Agricultural Engineering Energy Series
Fifty-four percent (1.2 billion acres) of land area in the 48 continental United States consists of grasslands, shrublands and open forests. For the most part, there is no alternative use of these land resources in production of food for man other than by way of ruminant animals. Sixty-nine percent (835 million acres) of these land resources is being utilized by grazing animals and forms the basis for a livestock industry which represents 43% of all agricultural receipts in the United States.

Energy In The Home: Energy Usage In Agricultural Production, John N. Walker
Agricultural Engineering Energy Series
Agriculture, even in its most primitive state, includes activities related to the collection and storage of solar energy in a form that can be used to sustain life. Energy must be expended in terms of human labor, animal labor, and fossil energy used for products and machinery utilized by agriculture. Because fossil energy is in short supply, many people are concerned, and rightfully so, about the effect that restricted energy availability will have upon agriculture production.
Priority Programming For Highway Reconstruction, Charles V. Zegeer, Rolands L. Rizenbergs
Priority Programming For Highway Reconstruction, Charles V. Zegeer, Rolands L. Rizenbergs
Kentucky Transportation Center Research Report
An adequacy-rating procedure was developed for use in priority programming for highway reconstruction. The procedure makes use of 15 roadway and traffic elements to rate highway sections in urban and rural areas based on 100 points. Condition elements (35 points) include a subjective rating of highway foundation, pavement surface, drainage, and maintenance economy. Safety elements (35 points) are stopping sight distance, highway alignment, skid resistance, accident experience, and traffic control devices. Service elements (30 points) include shoulder width, passing opportunity, rideability, surface width, volume/capacity ratio, and average speed.
Some of the advantages of the new procedure include computerized analysis of …

Analysis Of Weekday, Weekend, And Holiday Accident Frequencies, Jerry G. Pigman, Rolands L. Rizenbergs, Donald R. Herd
Kentucky Transportation Center Research Report
On rural roads, the largest number of accidents have occurred on Saturdays, Fridays, and Sundays, respectively. Tuesdays generally had the lowest number of accidents. The highest accident rates for two-lane roads were on Sundays and Saturdays, and the rates for expressways (interstates and toll roads) were the highest on Sundays. Accident rates on weekends were substantially higher than on weekdays. Rates of fatal and all accidents were lower during holiday periods than during weekends not involving holidays. Holiday periods had fewer accidents per day than weekends but had more accidents per day than weekdays. Traffic during holidays, however, was significantly …

Kentucky Transportation Center Research Report
A method of designing asphaltic concrete overlays has been developed from (1) Kentucky's theoretical 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 has been expressed as reduced or effective thicknesses of new-quality materials producing the same measured dynamic deflections. The total thickness required for the future …
Seatbelt Usage In Kentucky [Nov. 1978], Kenneth R. Agent, Michael Barclay, Robert C. Deen
Seatbelt Usage In Kentucky [Nov. 1978], Kenneth R. Agent, Michael Barclay, Robert C. Deen
Kentucky Transportation Center Research Report
In this report, the effectiveness and usage of seatbelts in Kentucky and factors affecting usage are examined and identified. Data were obtained from three sources: field observations, accident reports, and a questionnaire.
Kentucky drivers and passengers were found to have lower seatbelt usage rates (slightly under 10 percent) than drivers and passengers in other states. The accident data showed that the chances of being killed or severely injured is greatly reduced by wearing a seatbelt. Seatbelts reduced the chance of being killed by a factor of six and the chance of being severely injured by a factor of two. Several …

Statewide Survey Of Skid Resistances Of Pavements [Nov. 1978], Rolands L. Rizenbergs, James L. Burchett
Kentucky Transportation Center Research Report
In 1969, a research-type, skid-test trailer was acquired, U.S. routes were surveyed in 1970 and 1971, and the interstate and toll-road systems were surveyed in 1971. The data were used for research purposes and have been reported. The interstate and toll-road systems were surveyed again for research purposes in 1974. Since October 1974, surveys have been performed under highway safety project grants (interaccounted to 108, subsection OSKID). Primary and principal secondary roads, involving 4,613 miles (7,427 km), were surveyed in 1975. A second skid tester, a survey-type, was acquired in April 1976; and survey-testing of major, rural collector roads continued …
Pavement Evaluation Using Dynamic Deflections, Gary W. Sharpe, Herbert F. Southgate, Robert C. Deen
Pavement Evaluation Using Dynamic 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 …

Energy In Agriculture: Dryeration Performance Evaluation, Otto J. Loewer, Thomas C. Bridges, G. M. White, Robert L. Fehr, Larry W. Turner
Agricultural Engineering Energy Series
When grain is dried using continuous flow or portable batch dryers it must be cooled before it is placed in storage. The cooling process removes the sensible heat that was used to bring the grain temperature up to the drying air temperature, and hopefully reduces the grain temperature to a point where mold growth is no longer a problem. Unfortunately, rapid cooling of grain results in increased grain damage in terms of stress cracks, and is an energy-inefficient process in that the heat stored in the grain is not used for any useful purpose.

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.

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

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 …

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

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

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 …

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.
