Does Use Of Gypsum Improve Soil Structure In Kentucky?, V. P. Evangelou, Kenneth L. Wells

Soil Science News and Views

Gypsum is sometimes recommended as a soil amendment in order to improve structure. Although this practice is often used for reclamation of sodic soils (Na⁺ saturated) in the western USA, it's value in improving soil structure in Kentucky is questionable. The following discussion explains way.

Hydropower Turbine System, David T. Kao

Civil Engineering Faculty Patents

There is disclosed a new cavitation free hydraulic turbine system which fully utilizes well-established hydrodynamic theories useful for low-head hydroelectric applications. The hydropower turbine system of the present invention makes use of a fixed blade propeller turbine with reverse blade angle and an upward flow passage. To eliminate the complex flow control adjustable vane system and elaborate tube design and construction of the prior art, the new turbine system is provided with a vertical needle valve and a near zero absolute velocity free exit flow design.

Weed And Feed, William W. Witt, Harold B. Rice

Soil Science News and Views

Fertilizer and herbicide combinations are often applied prior to planting, at planting, or after crop emergence, a procedure sometimes called "weed and feed". The opportunities for utilizing this system are numerous with the major advantage being saving an extra trip across the field. In order for the system to work, it must ensure that both fertilizer and herbicide are present when needed. When both the crop plant and weedy plant are at growth stages which allow for compatible applications with a single treatment, this can be highly successful. Conversely, when these two plant systems are not at compatible growth stages, …

An Evaluation Of Elastizell Concrete As A Lightweight Fill Material, David L. Allen, Bobby W. Meade

Kentucky Transportation Center Research Report

Near Northern Kentucky University in Campbell County, Kentucky, access ramps connecting I 275 and 3-Mile Road (shown in Figure 1) were constructed. During construction of those ramps, additional embankments were to be placed on an existing 6-foot by 5-foot box culvert. Both ramps, hereafter referred to as NKU-1 (the exit ramp from I 275) and NKU-2 (the entrance ramp to I 275), cross the culvert. The new embankments would result in fill heights, over the culvert of 30 feet at Station 39+14 of NKU-1 (Figure 2) and 47 feet at Station 11+68 of NKU-2 (Figure 3). The original fill height …

Vanpool Demonstration Project (University Of Kentucky), Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

A vanpool demonstration project was operated at the University of Kentucky for the period May 2, 1983, through March 31, 1984. One van originated in Berea (roundtrip 90 miles) and another in Richmond (roundtrip 60 miles). Many problems associated with a vanpool operation were minimized because the riders were University employees and van ownership remained with the University.

It was found that personal contact with potential vanpool riders was much more effective then letters and questionnaires in the effort to generate initial ridership. Because vanpools had not previously been operated extensively in this area, it was difficult to convince potential …

Summary Of Alfalfa Variety Trials In Kentucky (1971-1983), Roy E. Sigafus

Agronomy Notes

This note shows comparable yields for 22 out of 100 alfalfa varieties which have been tested in at least three trials at Lexington or Princeton since 1971. Varieties not listed include many taken off the market, varieties known to be unsuited to Kentucky, or those which need further testing.

Yield results from seven separate trials are given in Table 1 as average annual dry matter yields (T/A) and as % relative yield (RY) as compared to Vernal. Vernal was used in each trial as a standard check and on the soils of limestone origin at Lexington and Princeton averaged over …

Causes Of Soil Compaction And Ways To Minimize Them, Lloyd W. Murdock

Soil Science News and Views

In order for a soil to become compacted, two conditions must be present, pressure and a soil that will compact . Different soils have different compaction characteristics. Sandy loam soils compact most readily; however, most soils with a high percentage of sand compact easily. Silt loam soils are more resistant to compaction, but they too are easily compacted when wet. When silt loam soils are not wet, it requires high pressure to compact them. When the soil is wet, each particle is lubricated and less pressure is required to compact the soil. Clayey soils can be compacted; but, as they …

Specially Constructed Bridges: Activities For Fiscal Year 1983, Theodore Hopwood Ii, James H. Havens, Gary W. Sharpe

Kentucky Transportation Center Research Report

The field performance of bridge features including masonry coatings, galvanized steel, weathering steel, conventional deck reinforcing steel, and epoxy-coated reinforcing steel were examined either visually or nondestructively on various pre-selected bridges throughout Kentucky. Additionally, a nationwide survey of state highway authorities was conducted on the application and service performance of stay-in-place forms.

All of the bridge features inspected appeared to be performing satisfactorily, except for the masonry coating failure on the I-471 twin bridges over the Ohio River at Newport. Results of the stay-in-place form survey support their application as a cost-saving feature.

Variable Serviceability Concept For Pavement Design Confirmed By Aasho Road Test Fatigue Data, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

Fatigue data from the AASHO Road Test were plotted for each level of serviceability. The Kentucky thickness design system uses the concept of a variable level of serviceability as a function of EALs. The Kentucky thickness design curve for the equivalent CBR was converted to an equivalent structural number and superimposed on each of the specific serviceability figures. The AASHTO Equation C–14 of the 1972 AASHTO Interim Guide was evaluated for each level of serviceability and superimposed on its respective figure. Equation C–14 fits reasonably well for serviceability levels of 2.0 and 2.5 but does not fit the remining serviceability …

Variations Of Fatigue Due To Unevenly Loaded Axles Within Tridem Groups, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

The effect of unevenly distributed loads on the axles within a tridem has been shown to be very significant. Equations are presented that enable the equivalent load effect for equal load distribution to be adjusted for uneven loading. Considering the relative increase and the relatively small volume of trucks currently using tridems, the equation for all tridems without regard to locations on the vehicle is recommended at this time. Consideration should be given to using equations for individual load patterns as the volume of trucks using tridems increases and more weight data become available.

Structural Evaluation Of Asphaltic Pavements, Robert C. Deen, Herbert F. Southgate, Gary W. Sharpe

Kentucky Transportation Center Research Report

To evaluate projects involving approximately 200 route-miles of interstate and primary pavements in Kentucky and Tennessee in relatively short time frames, it was decided to test, analyze, and design overlays using test equipment (Road Rater) and procedures developed by the University of Kentucky Transportation Research Program. This paper presents the analysis methodology and the evaluation and overlay designs for selected projects, including the before-and-after analysis of milling on one project.

The Road Rater applies a dynamic sinusoidal loading of known force and frequency. The velocity of the vibration waves are measured by sensors and integrated electronically to obtain surface deflections. …
