Reflectorizing Surfaces For Signs And Markers, L. E. Gregg

Kentucky Transportation Center Research Report

The attached copy of a proposed special specification for reflectorizing surfaces for signs and markers is submitted with the recommendation that this be considered by the specification committee, and furthermore that it be considered tentative. The specification was drawn up at the request of the Division of Maintenance in order that they would have some basis for differentiating materials offered by different vendors when invitations for bids are taken. I am sure that Mr. Palmer and Mr. Ringo consider the matter urgent.

The Mechanical Anchorage Value Of The Transverse Wires In Welded Wire Reinforcement Fabric, Ernst August Weinel

Masters Theses

"The tests reported in this paper were performed in an effort to secure data concerning characteristic properties of Welded Wire Reinforcement Fabric. This fabric has been used, up to the present time, primarily for temperature reinforcement. Limited attention has been focused on its potentialities for use as main tension reinforcing steel, particularly concrete highway slabs and floor slab reinforcement for buildings. The manufacturers of the Welded Wire Reinforcement Fabric believe their product can be used to better advantage as main tension reinforcement in reinforced concrete structures both from an economic and structural viewpoint, than structural steel reinforcing bars"--Object of Research, …

A Study Of The Effect Of Blended Coarse Aggregate On Air Entrained Concrete, S. T. Collier, L. E. Gregg

Kentucky Transportation Center Research Report

This research with combined coarse aggregates in cement concrete was initiated at the request of the Director of Design as a direct result of the condition study made by the Division of Design in 1945. In the report on this study it was shown that on the basis of averages pertaining to 80 projects with crashed limestone totalling about 395 miles in length, and 70 projects with Ohio River Gravel totalling approximately 410 miles in length, the service record for pavements with the river gravel was far inferior to that of pavements containing limestone coarse aggregate.

Specifically, the summary of …

Experiments With Air Entrainment In Cement Concrete, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

In September, 1946, the Research Laboratory prepared and distributed a comprehensive report entitled. "A Summary of Experiments With Air Entrainment in Cement Concrete", which covered field and laboratory experimentation conducted over a period of six years. In February, 1947, specific recommendations based on this report and another dealing with the pressure method of determining air contents resulted in adoption of air entrainment for all concrete pavements and the pressure method as the only accepted method of control.

Among the several projects included in the six years of research were four experimental roads which, of course, are still in service. Although …

An Experiment With Expanded-Metal Integrating Mats In Bituminous Concrete Pavement, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

This is an initial report of an experiment dealing with the use of expanded metal mats placed between the binder and surface courses of a Class I bituminous pavement at a location where a bituminous pavement of different design had shoved under heavy traffic. The purpose of the mats, of course, was to integrate the pavement in both longitudinal and transverse directions; the theory being that a small portion of the pavement, when subjected to a force that would ordinarily cause shoving, could actuelly shove only if an entire section of the embedded mat could be moved by that force. …

Geology And Mines Of The Upper Blackfoot Valley, Montana, Thomas K. Shea

Bachelors Theses and Reports, 1928 - 1970

The purchase and continued operation of the Mike Horse mine in the Heddleston district, by the American Smelting and Re­fining Company, gives the Blackfoot Valley a renewed promise of a prosperous future in its role as a mining district. In the past, large amounts of placer gold were recovered from the gulches of the area, however, because of the transporta­tion facilities, only the upper portions of a few lodes were exploited by the early miners.

Rugose Corals Of The Madison Group, William R. Paine

Bachelors Theses and Reports, 1928 - 1970

One of the best types of index fossils, and one which occurs most plentifully in the Madison group of formations in Montana, and yet, one which has been little studied, is the group of rugose, or cup, corals. Perhaps this group of fossils has not been studied in detail because their distinguishing characteristics are mainly internal, and labo­ratory preparation in the form of thin section or polished surfaces is necessary to bring out these characteristics.

Kibbey Sandstone In Montana, Glen Shean

Bachelors Theses and Reports, 1928 - 1970

Much attention has recently been given, by geolog­ists, to prolific water bearing horizon and a potent­ial oil horizon, known as the Kibbey sandstone, which lies deeply buried under much of central Montana. In some local­ities the sandstone is dry, and its identification in cut­tings from deep wells has in many cases proved difficult.

Interim Report On Experiments With Western Kentucky Bank Gravel In Bituminous Concrete, Kentucky Highway Materials Research Laboratory

Bachelors Theses and Reports, 1928 - 1970

The great diversity on mineral wealth in Idaho establishes it as one of the principle mining states in the union. Mining first began in the state with the discovery of placer gold in the Pierce City district in 1861, and since that date has become one of the leading industries of the state.

Upper Cretaceous Sediment In Montana, Frank J. Frankovich

Bachelors Theses and Reports, 1928 - 1970

Cretaceous sediments in Montana record events during a period of unusual geologic interest. After a long period of extensive submergence of the area during Jurassic time, came a period of varying continental and marine deposition with consequent variations in the types of sediments laid down. A study of these variations, their extent, and their cause has been the primary object of this thesis.

The Problem Of The Tensleep Sandstone, George D. Mccarthy

Bachelors Theses and Reports, 1928 - 1970

Sandstone is probably one of the most important groups of rocks in existence today. The economic importance of so insignifi­cant a thing as a mass of sand grains grows with the true reality of the situation. By increasing our knowledge of grains of sand, or particles of sandstone in all their ram­ifications, it would undoubtedly reflect upon our everyday life by increasing commercial possibilities of an undevel­oped natural resource of Montana.

Isopach Maps And Discussion Of The Ordovician And Devonian Of Montana And Adjacent Areas, Arden F. Blair

Bachelors Theses and Reports, 1928 - 1970

The intensive postwar search for new petroleum horizons has resulted in widespread prospecting in the northern Great Plains. No commercial production has as yet been derived from Ordovician or Devonian rocks in Montana, but the relat­ively few tests that have penetrated to critical depths have disclosed encouraging conditions which merit further consider­ation, especially in Devonian strata.

Occurrence Of Native Copper Near Jefferson City, Montana, Terence G. Kirkland

Bachelors Theses and Reports, 1928 - 1970

Sometime prior to 1870, a group of prospectors made what was believed to be a "rich strike' on one of the tributaries of Prickly Pear Creek in Jefferson County, Montana. Instead of striking it rich, they had uncovered a native copper deposit, worthless to them because of its limited extent and remote location, but now of much interest to the geologist, and to the mining engineer because of its possible commercial value.

Electro-Deposition Of Iron From A Chloride Bath, Charles W. Noon

Bachelors Theses and Reports, 1928 - 1970

Iron was electro-deposited from a ferrous chloride bath. Studies were made of deposits formed when current density was varied, and fin­ally when both current density and temperature were changed. An attempt was made to lay the ground work for a long range study of the chloride bath, and to determine the most simple conditions possible for obtaining a smooth, even, and thick deposit.
