Some Effects Of Fabrication Practices On The Strength Characteristics Of Reinforced Concrete Culvert Pipe, Robert C. Deen, James H. Havens Feb 1963

Some Effects Of Fabrication Practices On The Strength Characteristics Of Reinforced Concrete Culvert Pipe, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

Underground conduits have been used for hundreds of years for drainage and water supply purposes. With the advent of railway and auto-mobile transportation, the use of underground conduits for drainage purposes beneath the roadways increased greatly. It soon became apparent that there was a definite need for knowledge concerning the manufacture, installation, and field behavior of pipe culverts. Accordingly, in the first half of the century, much attention and research has been directed toward the development and establishment of acceptable techniques and specifications fot the manufacture and installation of pipe culverts. This work has been accomplished by many individuals and …

Concrete, Bridge Decks: Deterioration, Coatings And Repairs, James H. Havens, William B. Drake Feb 1963

Concrete, Bridge Decks: Deterioration, Coatings And Repairs, James H. Havens, William B. Drake

Kentucky Transportation Center Research Report

This report is not wholly a culmination of a planned or programmed research project. It is a historical account of damage sustained by both new and old concrete bridge-decks -- through freeze-thaw, salt action, etc, -- and of some expedient repairs which have been effected. The problem of durability in concrete bridge-decks has become increasingly critical during the past ten years or so and is now a major concern to highway engineers throughout the northern tier of states. While there is not yet a concerted agreement in regard to the cause of the trouble, relief is being sought through improved …

A Study Of The Hydraulics Of Drop-Inlet-Type Culvert Models, Ronald D. Hughes Jan 1963

A Study Of The Hydraulics Of Drop-Inlet-Type Culvert Models, Ronald D. Hughes

Kentucky Transportation Center Research Report

In certain unique situations, a drop-inlet-type of culvert might be employed to a greater advantage than the standard box- or pipe-type culvert. A drop-inlet consists merely of a vertical drop-section at the upstream end of the culvert. The drop section is connected to the main barrel of the culvert by means of an elbow or merely a rightangle intersection. The entrance to the drop-section must collect and funnel the channel water into the drop section. Thus, intercepting dams and sidewalls may be needed to form the entrance. Figure 1 illustrates, in a general way, some of the options which may …

Third Annual Performance Survey Of Reinforced Concrete Pipe Culverts, Ronald D. Hughes Jan 1963

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

Kentucky Transportation Center Research Report

In April, 1957, under Circular Memorandum 22-40, the Bureau of Public Roads issued a rational criterion covering beddings of reinforced concrete pipe, construction methods, and simplified methods for determining the allowable heights of fill over pipe having given D-load strengths. The states were urged to adopt the criterion; and, accordingly, the Kentucky Department of Highways issued Amendments No. 15 and 16 (Feb, 28, 1958) to its 1956 edition of Standard Specifications for Road and Bridge Construction and Standard Drawings Nos. 11.22 and 11.23. These amendments and standard drawings were patterned after the criterion of the Bureau of Public Roads but …

Construction Report On Experimental Use Of Natural, Bituminous, Quartz Sandstone (Kentucky Rock Asphalt) As A Traffic-Bound Aggregate, George R. Laughlin Dec 1962

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 …

Study Of Light Compaction-Equipment For Maintenance Patching, Robert L. Florence Sep 1962

Study Of Light Compaction-Equipment For Maintenance Patching, Robert L. Florence

Kentucky Transportation Center Research Report

Patching pot-holes and resurfacing small areas of pavement entail certain compaction-equipment difficulties for the maintenance crews. Areas in need of repair are often small but may be widely scattered. Large steel-wheeled rollers are difficult to transport from one location to another and tend to bridge across small, deep pot-holes. The bridging effect can be reduced by use of small rollers or pneumatictired rollers, which conform better to the area to be patched. The efficiency of a patching crew depends greatly upon its mobility. The compaction equipment, therefore, should be portable, should conform to the area to be repaired, and should …

The Kentucky Department Of Highway’S Scholarship Program, D. V. Terrell Jun 1962

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 …

Structural Repair Of Concrete Pavement, Barren County Project U 543(3), William B. Drake Jun 1962

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.
