Construction And Interim Performance Of Silica Sand-Asphalt Surfacing, Robert L. Florence Feb 1965

Construction And Interim Performance Of Silica Sand-Asphalt Surfacing, Robert L. Florence

Kentucky Transportation Center Research Report

The report submitted herewith emanates from continuing efforts to develop sand-asphalt surfacing to a high degree of perfection and as a possible alternative to Class I, Type A, bituminous concrete surfaces. This type of surface excels in skid-resistance and may evolve as a preferred method of surface renewal and de-slicking for worn pavements which are otherwise structurally substantial. This report is concerned principally with observations afforded by the aforenamed, State construction project; it is, in that sense, an interim report.


Experimental Concrete Pavement Containing Fly Ash Admixtures [1965], Ronald D. Hughes Jan 1965

Experimental Concrete Pavement Containing Fly Ash Admixtures [1965], Ronald D. Hughes

Kentucky Transportation Center Research Report

A 2.388-mi section of four-lane highway in Louisville, Ky., was selected for an experimental fly ash concrete pavement installation. The project was divided into three sections: a control section and two experimental sections containing 94 and 140 lb of fly ash per cubic yard, respectively. The solid-volume of fly ash in excess of that required to replace one sack of cement was considered as fine aggregate. The water was adjusted to provide a slump of approximately 2½ in., and an air-entraining admixture was proportioned at the mixer to provide an air content of approximately 4.5 percent.

Beams and cylinders were …


Experimental Feature, Construction Project F 160(10), U.S. 127, Mercer County, Experimental Guardrail Installations And Performance Studies, James H. Havens Nov 1964

Experimental Feature, Construction Project F 160(10), U.S. 127, Mercer County, Experimental Guardrail Installations And Performance Studies, James H. Havens

Kentucky Transportation Center Research Report

The report submitted herewith pertains to an experimental installation of aluminum guardrails which was completed in February, 1963. Progress reports, as required by PPM's 60-2 and 50-1.1, have been pending since the project began; however, all of the eligible information has been combined into the current report. Of course, long-time performance histories cannot yet be documented; and, for that reason, the report is considered to be interim rather than final.


Camber Design Study For Concrete Pipe Culvert, Robert C. Deen Nov 1964

Camber Design Study For Concrete Pipe Culvert, Robert C. Deen

Kentucky Transportation Center Research Report

When a pipe culvert is constructed on or near the natural ground surface and covered by a highway fill or embankment, the weight of the embankment compresses and consolidates the foundation soil, settlement occurs, and the culvert subsides and sags below the original grade line. Experience has shown that culverts which become clogged with silt and debris, become disjointed and faulted, leak, become undermined, and endanger the stability of the embankment. These and other damages attendant to settlement restrict the flow of water, prevent adequate inspection of the structure, and may eventually require extensive maintenance or complete replacement of the …


Use Of Kentucky Rock Asphalt For De-Slicking Purposes, James H. Havens Nov 1964

Use Of Kentucky Rock Asphalt For De-Slicking Purposes, James H. Havens

Kentucky Transportation Center Research Report

According to Joe Creason's report appearing in the Courier-Journal June 23, 1957 (copy attached), the Kentucky Rock Asphalt Company elected, June 14, 1957, to liquidate. Among the assets was a stockpile of material which was valued at $197,000 (I recall that the stated price, F.O.B. Sweden, in 1955 was $7.00 per ton); this calculates to be 28,140 tons-- which is a small quantity in comparison to the gross production (200,000 to 275,000 tons; $1.2 to $1.75 million) during some prior years. Apparently 1956 was the last year of sales, and I believe that Kentucky was the sole purchaser. Perhaps as …

Use Of Preformed, Compressed, Neoprene Seals In Joints Of Concrete Bridge Decks, Ronald D. Hughes Jul 1964

Use Of Preformed, Compressed, Neoprene Seals In Joints Of Concrete Bridge Decks, Ronald D. Hughes

Kentucky Transportation Center Research Report

Two types of seals are proposed for installation in contraction and construction joints in Ramp A, Ramp B, and the Main-Line structures from Third Street to Preston Street on Project I64-2(24)4, Jefferson County. The majority of contraction and construction joints are to be sealed with the preformed, compressed, neoprene seals. Specific joints in each structure will be sealed with cold-applied, elastomeric-type, joint-sealing compound; and these will be used as control joints for evaluation of the preformed, compressed, neoprene seals. Installation of all seals will be observed, and inspections will be made periodically. The performance of mastic-type sealants in joints in …


Kentucky Rock Asphalt, Traffic-Bound Bases, George R. Laughlin Jun 1964

Kentucky Rock Asphalt, Traffic-Bound Bases, George R. Laughlin

Kentucky Transportation Center Research Report

Kentucky rock asphalt (a medium-grained quartz sandstone impregnated with natural bitumen) occurs as major deposits in Edmonson, Grayson, Hardin, Breckinridge, Logan and Warren Counties. Physiographically these deposits occur along the southeastern margin of the Western Coal Field. Geologically the Caseyville formation (particularly the Bee Spring member) of the Pottsville series of the Pennsylvania strata and the Hardinsburg and Cypress sandstones of the Middle Chester series of the Mississippian strata are of interest. The areal geology of Kentucky is shown in Figure 1 and the locations of rock asphalt deposits are depicted in Figure 2.

A Study Of The Effects Of Quick Freezing On Saturated Fragments Of Rocks, John W. Scott, George R. Laughlin Feb 1964

A Study Of The Effects Of Quick Freezing On Saturated Fragments Of Rocks, John W. Scott, George R. Laughlin

Kentucky Transportation Center Research Report

Quick freezing of a fragment of rock which is fully saturated with water is, perhaps, the most rigorous of all tests for soundness, durability, or resistance to weathering. So-called soundness or quality tests employed currently, or heretofore, for evaluating concrete aggregates are usually less rigorous inasmuch as the state of saturation at the outset of freezing is not at a critical level. Hence, the number of freeze-thaw cycles endured by a rock specimen undergoing freezing and thawing in the presence of available water may merely reflect the duration of the exposure before the rock becomes vulnerable to damage -- i.e., …


A Laboratory Investigation Of The Properties Of Coal-Bitumen Paving Mixtures, Gary Grant Howard Feb 1964

A Laboratory Investigation Of The Properties Of Coal-Bitumen Paving Mixtures, Gary Grant Howard

Kentucky Transportation Center Research Report

The principal objective of this study was to investigate the feasibility of using coal, and to a lesser extent coal mine wastes, as aggregate in bituminous paving mixtures. These local aggregates were laboratory tested in bitumen-aggregate mixtures and, more particularly, in so-called cold-mixes. The bitumen-aggregate mixtures were evaluated by the Immersion-Compression Test, ASTM D 1075-60, with modifications for cold mixtures recommended in the Public Roads Journal (4).

In this initial study, since it was not possible to evaluate all types of mixtures, the primary question of whether coal and its waste products can be used as road aggregate could not …


A Rheological Investigation Of Asphaltic Materials, W. A. Mossbarger Jr. Jan 1964

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 Jan 1964

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 …

Interim Report On Rural Secondary, Base Stabilization Projects, Robert C. Deen, J. D. Shackelford Jun 1963

Interim Report On Rural Secondary, Base Stabilization Projects, Robert C. Deen, J. D. Shackelford

Kentucky Transportation Center Research Report

Early in 1962, the Division of Rural Highways selected several base stabilization projects for construction during the 1962 season. These projects were to involve the addition of 1-1/2 to 3 inches of compacted granular base to existing, rural secondary, traffic-bound macadam roads. Since these roads were not intended to be surfaced, calcium chloride and sodium chloride were to be added to the additional granular base material in an attempt to retain or "hold" the aggregate on the road. This treatment was in tended to improve the road and to build up the base over a period of a few years …

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 …

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 …
