Kentucky Transportation Center Research Report

This report which presents results from additional study of the Sandstone Test Road located on S.R. 30 in Magoffin and Breathitt Counties, is a supplement to Report No. 1 dated April, 1952. The project consisted of a laboratory investigation and construction of a 20-mile test road, with all the original work carried out over a period from early 1950 to November 1951.

Details concerning both laboratory and field work are contained in Report No. 1 and need not be discussed here. However, to keep the general objectives of the study clear, they are restated as follows:

Application Of Geology To Highway Engineering In Kentucky, L. E. Gregg, James H. Havens

Kentucky Transportation Center Research Report

Kentucky, too, is a state where geology abounds. Little credit for this, however, lies with the highway field, because such a prosaic subject is frequently overshadowed by such features as Mammoth Cave, Sky Bridge, Cumberland Falls, Pine Mountain, and extensive underground mineral deposits. Nevertheless; the influence of geology in the highway industry is growing, and it is obvious that some potential contributions have not yet been realized.

A Combination Waterbound Macadam And Dense-Graded Aggregate Base For Flexible Pavements, William B. Drake

Kentucky Transportation Center Research Report

This paper is concerned with a flexible base designed primarily to improve the riding qualities of high-type bituminous pavements. Difficulties in control of grades and sections with modern methods of macadam base construction have emphasized needs for effective finishing procedures.

In the project described, an 8-in. base was built in two courses, the lower waterbound macadam being overlain by a densegraded aggregate material suitable for spreading and shaping with a power grader. The base was then surfaced with two courses of a hot bituminous plant mix.

Observations and measurements showed that the combination could be built satisfactorily; construction entailed more …

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 …

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 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 …

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 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 …

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.

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 …
