An Investigation Of The Behavior Of Asphalt Stabilized Sand In Triaxial Compression Testing, Joseph P. Callahan

Civil Engineering ETDs

More and more in highway construction, the engineer is faced with the problem of locating satisfactory materials to be used in the construction of highways. This problem has become very critical in the selection of a satisfactory aggregate to be used in many phases of the construction. In large metropolitan areas and in other regions of the United States unblessed with an abundance of this aggregate, it was found that where once there was no shortage of suitable material, the supplies have now been practically exhausted.

Performance Of A Reinforced Concrete Pipe Culvert With Standard And B1 High Fill Bedding Under Rock Embankment, Ralph R. Taylor

Kentucky Transportation Center Research Report

In co-operation with the Bureau of Public Roads, a number of reinforced pipe culvert installations in a number of states have been selected to evaluate the effectiveness of the design and construction criteria. One particular pipe has been chosen for this special study because of its installation conditions. This pipe is located on I 75-6 (5) 123 in Scott County at Station 37 + 50, US460, SW Ramp, and has been constructed using both type beddings that are specified in the 1956 edition of the Kentucky Department of Highways Standard Specifications for Road and Bridge Construction and amendments thereto. Observation …

Pavement Surveys, Milton Evans Jr.

Kentucky Transportation Center Research Report

The major considerations in the evaluation of a slab's condition, where surface defects exist, are the number of defects, their type and size. It is possible for a slab to contain a large number of surface intrusions without being appreciably damaged, if the impairments are all very small. On the other hand, only a few very large defects would be very damaging. Certainly, the most satisfactory condition would be the complete absence of blemishes.

In the surveys which have been made since the beginning of these pavement investigations, soil holes, chert pop-outs, shale pitting, trash imbedments and cracks have comprised …

Digital Computers And Their Application To Civil Engineering Problems, Richard G. Vaughan

Civil Engineering ETDs

Early in 1960 a study was undertaken by the author to become acquainted with the use and application of digital computers in the structural and civil engineering fields. After several months study and attendance, during the summer of 1960, at a National Science Foundation Institute on the use of digital computers in engineering, it was felt that the study could be expanded and presented in thesis form. The principal benefit from the study, other than the author's, will possibly be the integration into the civil engineering curricula of the material contained in the thesis.

The material as presented is the …

The Use Of Ferrophosphorous And Manganese Ore In High Density Concrete For Radiation Shieding, Robert A. Crist Jr.

Civil Engineering ETDs

The scope of this thesis encompasses the investigation of the feasibilities of using a locally and/or readily available heavy aggregate for high density concrete. Such an aggregate was found to be available in Socorro, New Mexico. The Socorro Manganese Corporation has a stockpile of over 7,000 tons of high-grade manganese ore (specific gravity = 4.5) potentially suitable as a heavy aggregate, and some of which was used for this research. Along with the manganese ore was used ferrophosphorous, a very heavy aggregate manufacture by the Victor Chemical Works (specific gravity = 6.5), to obtain a range of densities that would …

Correlation Of The Atterberg Limits And The California Bearing Ratio Values For Soil-Cement Media, Vernon E. Kerr

Civil Engineering ETDs

Tests were made on three different soils, using controlled amounts of Portland cement and water. All tests were made using a standard liquid limit device or a six-inch mold. The variables were amounts of Portland cement, degree and thoroughness of mixing, moisture content, curing and compaction of samples. The recommended procedures for performing the Plastic Limits Test, Liquid Limits Test and the California Bearing Ratio Test were followed with very few exceptions. All values obtained from testing are entered in the report and no retesting was done.

Mix Design Study And Compressive Strengths Obtainable From Pumice-Aggregate Concrete, Benjamin F. Snow

Civil Engineering ETDs

Compressive strengths of pumice-aggregate concrete were examined by introducing controlled variables into the mix proportions. A mix design method is presented, and this method was analyzed for consistency and feasibility.

Experimental Determination Of Dynamic Stress Concentration Factors In Rectangular Steel Bars, Jerome E. Ligocki

Civil Engineering ETDs

Stress concentration factors obtained from impact tests indicate substantial agreement with experimentally derived static stress concentration factors. Testing was limited to one 3/8 diameter centrally located hole in a long rectangular bar 2 inches wide. The hole was located at a bar cross section where a plane wave was found to exist. Stress pulse lengths as short as 50 microseconds duration was used in the experiments.

The experimental results confirm the ability of the resistance strength gage to accurately measure stress pulses. The proper amplitude response of the gage is proven by comparison with dynamic and static test results. The …

Investigation Of Concrete Pavement Us-60 Between Versailles And Frankfort, Milton Evans Jr.

Kentucky Transportation Center Research Report

A complete survey of the above project was made between April 27, and May 13, of this year to deter mine the condition of the pavement after the second winter of service. The data from this survey include all of the approximately ten miles of four-lane highway, Tables I and II; all of the cross-overs, Table III; and the ramps and connecting lanes in the interchanges, Tables IV and V. Table VI covers the areas where several surveys have been conducted and Table VII is a breakdown of the total defects by type for the whole project. These tables are …

Crustacean Gastroliths From The Jackson Eocene Of Louisiana

School of Mines and Metallurgy Bulletins

Wechesia louisianae, n. sp., is described from upper Eocene beds at Montgomery, Louisiana. Second species of the genus, it extends the range of Wechesia Frizzell and Exline from Claiborne (middle) Eocene and validates the generic diagnosis.

The Influence Of Water-Reducing Admixtures On The Curing Of Concrete, Wallace Don Budge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water-reducing admixtures in concrete has grown continuously since their introduction over 25 years ago, with a present estimated usage in the production of 25 million cubic yards of concrete annually in the United States alone. Opposition to anything added to concrete, other than cement, aggregates, and water, is gradually disappearing, and considerable recognition is being given to the value of using other ingredients.

The research contained in this study may be divided into two portions: tests to determine the rate of volume change of cement paste and compressive strength tests to indicate the effect of moist curing …

Roadside Weed And Brush Control With Chemicals, D. G. Shurig, Jean E. Hittle

Indiana Local Technical Assistance Program (LTAP) Publications

This bulletin, developed primarily for the highway engineer and the county road supervisor, describes the more important herbicide materials available for roadsides, their recommended use, and application methods. Information is also provided to help county road officials develop better weed and brush control programs for county road systems. The last part of the bulletin covers details of planning a county-wide weed and brush control program.

Soil Moisture As A Factor In Streamflow Forecasting For Logan River, Utah, Yu Kam Fok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Purpose

Forecasting the annual water supply in an arid area by using the water content of snow on watersheds on some particular date, such as April 1, has become a very useful practice. Although these forecasts have given results of great practical value, they have sometimes been considerably in error. Seeking to minimize error, forecasters have incorporated various additional data such as temperature and antecedent rain to improve the relation between snow measurement and measured runoff.

Numerous methods have been suggested in the search for a reliable streamflow forecasting equation and various data have been used. Nearly all of the …
