A Rheological Investigation Of Asphaltic Materials, W. A. Mossbarger Jr.

Kentucky Transportation Center Research Report

Asphalts, serving as cements or binders in bituminous pavements, behave essentially as purely viscous, mobile, liquids at high temperatures and assume varying degrees of viscoelasticity, plasticity, elasticity, etc., upon cooling. They stiffen to a semi-solid state at cold temperature and do not. exhibit a discrete melting or freezing point, Saal (1)* classifies bitumens into three types according to their rheological properties at normal temperatures. They are: 1) those which behave entirely or almost entirely like Newtonian liquids, 2) those which show elastic effects during initial deformation and which exhibit Newtonian flow thereafter, and 3) those which show almost complete resilience …

Fourth Annual Performance Survey Of Reinforced Concrete Pipe Culverts, Ronald D. Hughes

Kentucky Transportation Center Research Report

A stylized, rational criterion for the structural design and installation of reinforced concrete pipe culverts was developed by the Bureau of Public Roads in cooperation with Prof. M. G. Spangler of Iowa State College and the American Concrete Pipe Association and was distributed to the various state highway agencies, April 4, 1957, as Circular Memorandum 22-40.* The criterion was intended to bring together and simplify methods for computing the strengths required for various fill heights and conditions of bedding. The several highway agencies were urged to adopt the criterion for use on all Federal-aid projects and accordingly, the Kentucky Department …

Utah State University Stilling Basin Pipe Flow To Open Channels, Hameed Rasheed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Energy dissipation problems are often encountered where pipelines discharge into open channels. Normal pipe flow velocities most often result in super-critical velocities in canals. These high velocities may cause scour, overtopping, and unstable flow in the channel.

The principal objective of the study was to find an efficient and economical design of a stilling basin transition from pipe flow to open channels. Pertinent variables were selected and their effects determined by extensive experimentation.

An efficient stilling basin was developed utilizing a short dissipator pipe on the wall opposite the inflow pipe. The optimum diameter, length, and differential elevation between center …

Construction Report On Experimental Use Of Natural, Bituminous, Quartz Sandstone (Kentucky Rock Asphalt) As A Traffic-Bound Aggregate, George R. Laughlin

Kentucky Transportation Center Research Report

Major deposits of natural, bituminous, quartz sandstone (Kentucky Rock Asphalt) occur in six counties of western Kentucky and a few minor deposits occur in eastern Kentucky. Crushed rock asphalt has been used extensively in Kentucky and elsewhere for over 50 years for surfacing roads.* The most productive area was in Edmonson County where the Caseyville and Bee Springs formations were quarried and mined. These deposits have been described as oil-pools which are now defunct and from which only the asphaltic residue remains. The bitumen content of the rock varies locally in a quarry or mine; and, because of this, enormous …

Investigation Of Aggregate Occurrence In Logan County, Kentucky, George R. Laughlin

Kentucky Transportation Center Research Report

As requested in your memorandum of September 12, we have conducted an extensive series of tests on the natural sand produced by Kapco Construction Company in Logan County. There was some question regarding the classification of the sand -- whether it would be termed a manufactured, a crushed conglomerate, or a natural sand. I had Mr. George R. Laughlin, Geologist of the Research Division, visit and inspect the pit. A copy of Mr. Laughlin's report to me is attached for your file. He reports that the material being produced is a washed, natural sand and similar in production procedure to …

Laboratory Test Results On Natural Sand Produced By The Kapco Construction Company In Logan County, Ronald D. Hughes

Kentucky Transportation Center Research Report

On September 19, 1962, a sample of sand produced by the Kapco Construction Company was received by the Research Division. This material was sampled at the quarry in Logan County and forwarded to the Research Division by personnel from District No. 3 of the Bowling Green Office. The sample was submitted for laboratory evaluation in regard to possible use of the material as fine aggregate in Class A concrete.

Special Provisions For Non-Leafing Aluminum, Basic Lead Silico-Chromate Oil-Alkyd Finish-Coat Paint For Guard Rails And Bridges, William B. Drake

Kentucky Transportation Center Research Report

These provisions cover the material requirements for a pre-mixed, non-leafing aluminum, basic lead silico-chromate, oil-alkyd finish-coat paint which is intended for use in one or two finish-coat applications. This paint is considered to be compatible with undercoat paints currently covered by Special Specification No. 14-56b and may be substituted for the green finish-coat, Para. IV, therein, when so indicated by appropriate notations on the plans, proposals, invitations, etc. This paint may be used for either new or re-paint work on bridges, guard rails, and other steel structures as may be designated. Undercoat paints, when required, shall be in accordance with …

The Kentucky Department Of Highway’S Scholarship Program, D. V. Terrell

Kentucky Transportation Center Research Report

The Kentucky Department of Highways was organized in 1912, at that time the field of highway engineering was new, little was actually known about the scientific process of building roads, there were no highway engineers as such. The civil engineer because of his experience in the construction of railroads and public works was to become the highway engineer in the future. As road building began to be an important fact, most schools added courses in highway construction to the already over-crowded field of civil engineering, and highway engineering today is considered on of the major branches of the broad field …

Processed Kentucky Rock Asphalt, P. F. Phelan

Kentucky Transportation Center Research Report

Attached are three copies each of two laboratory reports covering tests on a 50 lb. sample of processed Kentucky rock asphalt forwarded to our laboratory by Mr. C. H. McKinney. The sample arrived June 6. These reports include results of laboratory analysis and evaluation tests - and small scale road tests - to determine the proper amount of tar to be added to the processed material to produce a satisfactory road surfacing mixture.

Structural Repair Of Concrete Pavement, Barren County Project U 543(3), William B. Drake

Kentucky Transportation Center Research Report

The Research Division assisted the District Construction personnel with structural repairs of five areas of cement concrete pavement that had been adjudged unsatisfactory. I had an opportunity to observe the repaired areas on July 19, 1962, and they all appear to be performing. adequately. The color of the epoxy patching material does not completely match the adjacent concrete but with normal weathering the two materials should approach a better match.
