A Concrete Pavement Without Transverse Joints [Dec. 1952], William B. Drake

Kentucky Transportation Center Research Report

This project was last reported in January, 1951, or approximately two years ago. Three previous reports have been made. Report No. 2 was dated December, 1949, and Report No. 1 was made July, 1949. A memorandum report (for file only) covering the two 1951 inspections was made in February of 1952.

This road is a section of U.S. 31W in Simpson County designated as FI 239(4). It runs from Sta. 9-11 at the Tennessee State Line to Sta. 311-40 at the south city limit of Franklin (see layout plot). It consists of a 22-foot concrete pavement underlain by 1-1/2 inches …

An Investigation Of Lean Concrete Mixes As Base Courses For Bituminous Surfaces [Dec. 1952], Dave H. Sawyer

Kentucky Transportation Center Research Report

During the summer of 1950, the Kentucky Department of Highways placed a lean concrete mix for base construction and widening in Montgomery County. This project was a 4.415 mile section of U.S. 60 on the Winchester-Mt. Sterling Road, and was designed as SF 87-117. Four major revisions – three alignment and one grade – were completed on the project thus requiring full-width base replacement of sections of the old pavement with the lean concrete mix.

A Compendium On Class I, Type C Mixes, Ellis G. Williams

Kentucky Transportation Center Research Report

Recently the Class I, Type C Surface Mix has been the subject of numerous discussions resulting from present paving operations on Muldraugh Hill (U.S. 31W and U.S. 60) south of Louisville, and from performance of pavements placed heretofore on some Louisville Streets. Apparently, past difficulties have created some doubt about the suitability of Type C surfaces in heavy traffic areas for which it was intended. Type C does not represent the ultimate in stable mixtures, but it should be entirely adequate for the purpose intended.

A Survey Of Acidity In Drainage Waters And The Condition Of Highway Drainage Installations, James H. Havens

Kentucky Transportation Center Research Report

During the summer of 1949, approximately one year after installation, serious corrosion failures were discovered in a series of galvanized metal entrance culverts on U.S. 60 south of Ashland near Princess. Because of a unique disparity in their performance at this location, the problem was referred to the Research Division for possible explanation. An impromptu investigation ensued, and the cause of the failure was attributed directly to acid drainage water flowing from extensive strip-mining operations within the immediate area. A report (1)* describing the attendant conditions was made to the Research Committee in December of that year.

As an outgrowth …

The Performance Of Cold Mastic Joint-Sealing Compounds And Sawed Joints In Concrete Pavements, Dave H. Sawyer

Kentucky Transportation Center Research Report

Included in this report are observations and data on the performance of various types of crack and joint sealing materials applied to three separate concrete pavements. The factors which are considered pertinent in evaluating the respective conditions of the materials are: length of service, tightness of joint, adherence to the concrete pavement, and ductility. The three materials used on these projects were cold mastic, hot-poured asphalt rubber, and OA-2 cut back with MC-3.

A Bank Gravel Base Containing Calcium Chloride [Report No. 2], William B. Drake

Kentucky Transportation Center Research Report

Attached you will find our second progress report on "A Bank Gravel Base Containing Calcium Chloride," by W.B. Drake. This project pertains to that portion of the Paducah-Eddyville Road (U.S. 62) extending from Kentucky Dam to Kuttawa. You are quite familiar with the road having visited it in company with Mr. Bray on August 13, this year and I believe most of the members of the Research Committee are familiar with it. Discussions following presentation of Report No. 1 on the project at our meeting last April would have accomplished that, but the road is better known for the number …

Evaluation Of Traffic Paint In 1952, A. C. Peed Jr.

Kentucky Transportation Center Research Report

Following the program of in-service transverse stripe evaluation coupled with laboratory study of traffic paint samples submitted by various manufacturers who propose to bid on the Departments paint requirements, field stripes were placed August 19, 1952. For this test stripes were placed in the same general location as that used the two previous years (U.S. 27 south of Lexington at the junction of the concrete and bituminous pavements). Gradings contained herein were made December 27, 1952, and thus represent a somewhat premature five-month evaluation. However, the set of stripes placed in 1951 were scrutinized since they had sixteen months of …

A Limestone-Calcium Chloride Stabilized Base, William B. Drake

Kentucky Transportation Center Research Report

This report is mainly concerned with the calcium-chloride stabilized portion of a combination base. A 4-inch course of waterbound macadam was placed over a 1-inch insulation course overlying an existing traffic-bound stone surface. The next 4 inches of base above, the water bound material consisted of two 2-inch layers of calcium-chloride stabilized limestone of a design not used heretofore by the Department.

Bituminous concrete binder and surface courses laid over the base brought the total mat thickness to more than 11 inches. The surface width was 30 feet, and the length of the project was 1.1 miles.

Although the road …

Head Determinations For Structures On U.S 23 That Are Affected By Raising The Normal Pool Elevation Of Ohio River Lock And Dam No. 30 At Greenup, Kentucky, Eugene M. West

Kentucky Transportation Center Research Report

During a visit to this office on July 3, 1952, Mr. J.O. Cornell requested the assistance of the Hydraulics Section of the Research Laboratory in investigating the possible head to be expected on the drainage structures on U.S. 23, that would be influenced by the proposed raising of the normal pool elevation of Ohio River Lock and Dam No. 30 at Greenup, Kentucky.

In order to better evaluate the head to be expected, I have approached the problem from an analytical standpoint, outlining and comparing the results from three suggested methods. The results of the analysis of the three separate …

Corrosion Of Highway Structures By Acid-Bearing Drainage Water In Hopkins County, James H. Havens

Kentucky Transportation Center Research Report

Pursuant to your conversation with Mr. Hopgood concerning the above matter, Mr. Peed and I contacted Mr. Charlie Rogers, Resident Engineer, Madisonville, and made an inspection of the locations in question. In specific connection with this, you will recall from our Progress Report No. 1 on "A Survey of Acidity in Drainage Waters and the Condition of Highway Drainage Installations" that the acid conditions in Hopkins County were rated as extremely severe, if not the most critical in the state. It was, in part, due to the prevailing severity there that led to the selection of a location at Mortons …

Field Trip To Daviess And Henderson Counties For Inspection Of Gravel-Bituminous Roads, Ellis G. Williams

Kentucky Transportation Center Research Report

This series of inspections started April 28, with inspection of pavements containing gravel located in Daviess County. It was found that most pavements containing this aggregate has been resurfaced last year using a crushed limestone aggregate. There were, however, three hot-mix and one road-mix pavements remaining.

Proposed Special Specification For Reflectorizing Glass Spheres, James H. Havens

Kentucky Transportation Center Research Report

In response to your request for a specification that will apply to glass beads for reflectorizing surfaces of signs, paints, and other night driving aids, we recommend the attached material which is drawn up in the form of a proposed specification. In general, the procedures. and ranges of performance characteristics conform with things that have been discussed by the A.S.T.M. Subcommittee on Traffic Paints. Actually, A.S.T.M. has not adopted a specification, but probably they will have one within the next year or two.

You will note the refractive index and size distribution or gradation are referred to in the specification, …

A Study Of Runoff From Small Drainage Areas And The Openings In Attendant Drainage Structures, Eugene M. West, J. O. Cornell

Kentucky Transportation Center Research Report

In 1926, John T. Lynch read to the Kentucky Academy of Sciences a paper entitled, "The Relation Between Drainage Area and Waterway Required for Culverts and Small Bridges in Kentucky." The paper was based on a study of many small drainage structures then existing in the highway system, and a general evaluation of the performance of the structures in relation to rainfall and runoff from contributing watersheds.

As a result of this report, and in accordance with the suggestions contained in it, the Department of Highways adopted a system of runoff coefficients applicable to different sections of the state and …

A Bank Gravel Base Containing Calcium Chloride [Report No. 1], William B. Drake

Kentucky Transportation Center Research Report

This report is concerned with a bank gravel base construction project, and particularly with that part of the base containing calcium chloride as a stabilizing agent. The project was carried out on a relocation of U.S. 62, between Kuttawa in Lyon County and Kentucky Dam on the Tennessee River. A part of the project, as shown on the general location map in Fig. 1, was in Livingston County between the Cumberland and Tennessee Rivers.
