Latex-Concrete Overlays On Bridge Decks (I64, Mp 150 To West Virginia Line), James H. Havens, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

Visual field inspections and soundings were performed on latex concrete overlays on 24 bridges on I 64 between Milepoint 150 and the West Virginia state line. The inspections were conducted in response to a request from the Kentucky Department of Highways to determine if cracking problems in the overlays were related to workmanship or materials.

The field inspections revealed that most of the overlay crack problems were related to 1) reflection cracking caused by pre-existing fractures in underlying concrete bridge decks and 2) “pull-in” cracks in the overlay, caused by belated tyning of the bridge deck.

Field diaries, inspection reports, …

Modeling Of Overland Flow By The Diffusion Wave Approach, Rao S. Govindaraju, S. E. Jones, M. L. Kavvas

KWRRI Research Reports

One of the major issues of present times, i.e. water quality degradation and a need for precise answers to transport of pollutants by overland flow, is addressed with special reference to the evaporator pits located adjacent to streams in the oil-producing regions of Eastern Kentucky. The practical shortcomings of the state-of-the-art kinematic wave are discussed and a new mathematical modeling-approach for overland flows using the more comprehensive diffusion wave is attempted as the first step in solving this problem. A Fourier series representation of the solution to the diffusion wave is adopted and found to perform well. The physically justified …

Various combinations of the watershed characteristics were input and computer analyses done to obtain the required data base. …

Investigation Of Pollution In A Karst Aquifer Utilizing Optical Brightener, John Thrailkill, Ralph F. Wiseman, Bridget R. Scanlon

KWRRI Research Reports

Optical brightener is an additive to laundry detergents and is found contaminating groundwater. Its concentration may rapidly and inexpensively be determined by fluorescence techniques, and because its source is human wastewater, its presence in groundwater serves as a direct indication of pollution from septic tanks, sewer leaks, and landfills.

A total of 105 wells and springs in an area within the Inner Bluegrass Karst Region near Lexington, Kentucky, were described and sampled. Analyses were made for optical brightener (430 samples), total coliform (91), fecal coliform (93), and fecal streptococci (90). As many as 20 optical brightener and 4 bacterial samples …

Micronutrients In Kentucky, William O. Thom

Soil Science News and Views

Micronutrients required for normal plant development and fruiting include boron, copper, iron, manganese, molybdenum, and zinc. Unlike the macronutrients (N, P, K, Ca, Mg and S), the quantities of micronutrients needed by agronomic crops is very small. Kentucky soils may contain large amounts of micronutrients in their mineral composition but only small amounts may be available for plant uptake. The soil availability and crop uptake of micronutrients are influenced by soil pH, soil temperatures, crop root growth, soil moisture, crop species and soil organic matter content.

After 15 Years Of No-Tillage Corn, Robert L. Blevins

Soil Science News and Views

Farmers shifting from a system of agricultural production that includes intensive tillage operations to a reduced or no-tillage system are often concerned about how this change may affect soil properties and productivity. No-tillage leaves the residues and fertilizers on the soil surface with no mechanical incorporation and may result in soil properties greatly different from plowed soils.

Sampling Techniques For The Collection Of Vehicle Classification Data, Jerry G. Pigman

Kentucky Transportation Center Research Report

The question of what length of time is necessary to collect statistically reliable vehicle classification data is an important issue when manpower is limited. Varying local conditions may necessitate more classification data be collected at some locations than others. The use of short-term counts could produce significant savings. Supplementing manual counts with automatic classification equipment could reduce data collection costs and improve accuracy.

The objectives of this study were to review literature to determine the capabilities of automatic classification equipment and to analyze toll road data in Kentucky to determine if short time periods may be used to represent the …

Summary Report Of Ranking Methodologies, Robert C. Deen

Kentucky Transportation Center Research Report

Participants in the ranking methodologies workshops were a good representation of those various actors (types of agencies or organizations) in the pavement management process. There were nineteen participants, nine of whom were from the United States, six from Canada, and four from European countries. Of the nineteen, eight represented state or provincial governmental units, three represented municipalities, four were employees of national highway agencies, and another four were either consultants or representatives of universities. Unfortunately, however, all participants represented the technical levels involved in pavement ranking. No one was present to provide the viewpoint of the ultimate decision makers -- …

Analysis Of Movements And Forces On Bridge Approaches: A Case Study (Bridge Over Chesapeake Ave. On Interstate 471 In Campbell County, Kentucky), David L. Allen, Bobby W. Meade, Tommy C. Hopkins

Kentucky Transportation Center Research Report

A case study is presented of a bridge on Interstate 471 in Campbell County, Kentucky. The south approach to the bridge is a side-hill fill. During construction, the south intermediate piers tilted as a result of movement in the south approach foundation. Construction was temporarily halted on the south approach embankment, allowing pore pressures in the foundation to dissipate and slowing the movement. The piers were than reconstructed.

The south approach end bents were instrumented with earth pressure meters. The piles were instrumented with slope inclinometers. Most recent data show that movement is continuing and the present factor of safety …

Long-Term Movements Of Highway Bridge Approach Embankments And Pavements, Tommy C. Hopkins

Kentucky Transportation Center Research Report

Long-term movements of highway bridge approach embankments and pavements are described and factors that may lead to settlement of highway bridge approach pavements are discussed. Six case histories are presented. The bridge approach sites were observed at different times during the period 1966 to 1985. At four sites, lateral movements, measured from slope inclinometers, of the approach embankments were monitored over time periods ranging from 8 to 14 years. Settlements of the highway bridge approaches were monitored some three to four years after paving. Estimated and observed settlements of the foundations at the study sites were obtained for a length …

Separation Of Powers, Legislative Vetoes, And The Public Lands, Eugene R. Gaetke

Law Faculty Scholarly Articles

The Supreme Court's decision in Immigration and Naturalization Service v. Chadha struck a serious, if not fatal, blow to the constitutional acceptability of the legislative veto. In Chadha the Court held that a provision of the Immigration and Naturalization Act, which permitted one House of Congress to reverse a decision by the Attorney

General not to deport an alien, was a violation of the doctrine of separation of powers since it did not comply with the requirements of passage by both Houses of Congress and presentment to the President. In light of that decision, the constitutionality of nearly 200 statutes …

Development Of Accident Reduction Factors, Tom Creasey, Kenneth R. Agent

Kentucky Transportation Center Research Report

In order to use the cost-optimization procedure of dynamic programming to rank safety improvements, improvement costs and benefits must be input. The benefits are in terms of accident reductions resulting from specific safety improvements. In this study a comprehensive list of accident reduction factors were developed to use in the cost-optimization program. The development of the list of reduction factors was based mainly on a review of literature and survey of states, with limited input from a before-and-after accident analysis.
