A Discussion On The Durability Of Expanded Shale Aggregate For Exposed Concrete Structures (Bridges), James H. Havens

Kentucky Transportation Center Research Report

During the period between 1924 and 1934, in particular, numerous reinforced concrete bridges were built in Kentucky and elsewhere. Although many of them are still in service, they are some 30 years old and are showing the effects of time and weather. While it is true, of course, that they were constructed without the benefit of air-entrainment and without many present-day control practices, the influences of aggregate quality and freeze-thaw are usually apparent. The advent of the de-icing salt era, about 1940 and following World War II, introduced an additional deteriorating influence gnawing at old and new structures alike. The …

Criteria For Design Of Pavement Thicknesses, Kentucky Interstate Highways, William B. Drake, James H. Havens

Kentucky Transportation Center Research Report

The Kentucky Department of Highways, in 1946, sought a more systematic criteria and basis for designing the thickness of bituminous concrete pavements. The Research Division was authorized to pursue this work and to develop the criterion. These efforts were embodied in a report (1) to the Department, which offered a system of design based upon CBR's and EWL's. EWL's were computed originally for a 10-yr. period but this practice was revised in 1954, to encompass 20-yr. traffic (more realistic with respect to average road life). Then, in 1957, the Department requested a re-evaluation of the criteria from the standpoint of …

Experimental Paving Projects Using Curtiss-Wright’S Coal-Modified, Coal-Tar Binder [1960], James F. Hardyman

Kentucky Transportation Center Research Report

On April 7, 1959, the Curtiss-Wright Corporation announced the development of a new coal-based road paving binder, utilizing bituminous coal. This development was the result of their research program conducted in an effort to find new uses for coal and coal products. The basic principle used in preparing this bituminous binder was the digestion of powdered coal in coal tar and tar oils at temperatures of 500-600°F. By adjusting the proportions of tar, tar oils, and coal, binders could be prepared having penetration ranges comparable to asphalt cements. It was the intent of the developers that the modified binders be …

Proposed Specification For Bridge Paints, James H. Havens

Kentucky Transportation Center Research Report

On July 30, 1958, two proposed bridge paint system specifications were submitted by this Division for Department consideration. Since that time, there have been several discussion sessions between various paint industry, representatives, members of the Department Specifications Committee, and J. H. Havens, Assistant Director of Research. Mr. Havens has been requested by the Specifications Committee to re-write one of the specifications, BASIC LEAD SILICO-CHROMATE, OIL-ALKYD PAINT SYSTEMS FOR IRON AND STEEL STRUCTURES (BRIDGES), and to prepare an additional specification covering, PHENOLIC RESIN PENETRATING LIQUID PAINT SYSTEM FOR IRON AND STEEL STRUCTURES (BRIDGES).

Rockcastle (Pottsville) Conglomerate Sand Evaluation In Portland Cement Concrete, Milton Evans Jr.

Kentucky Transportation Center Research Report

In order to analyze the concrete making properties of a processed Pottsville Conglomerate Sand from Rockcastle County, Kentucky, several batches of portland cement concrete were made. Standard mixing control, strength, and durability tests as well as a short cut test to detect excessive expansion during curing were performed on the concrete. Control specimens were made utilizing an Ohio River Sand, typical for this area, as the fine aggregate. This sand which was acceptable by Kentucky Highway Department Specifications was produced by the Nugent Sand Company of Louisville, Kentucky. The sand was submitted for evaluation in this manner by the State …

Cold-Weather Concreting, Milton Evans Jr.

Kentucky Transportation Center Research Report

In order to successfully place concrete in cold weather, certain established requirements must be met. The concrete must not be allowed to freeze, it must not be overheated by artificial means in an attempt to protect it from the cold, and proper curing conditions must be maintained during the period of protection to insure sufficient moisture for the cement to hydrate. Generally, temperatures of not less than 50°F and not more than 90°F are satisfactory. These temperatures must be maintained long enough for the concrete to develop sufficient strength to withstand freezing temperatures and to support the loads. Generally, concretes …

Camber Design Study For Concrete Pipe Culverts, Aubrey D. May

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 or sags below the original line as illustrated in Fig. 1. The amount of settlement depends, of course, upon the fill height or load, the depth of foundation soil, and the susceptibility of the foundation soil to consolidation. In addition, and toward the toes of the embankment, the structure may tend to lengthen. It may lengthen slightly, however, simply because the distance …

Interim Status Of Tire Service Life Study, William B. Drake

Kentucky Transportation Center Research Report

The service life of selected, most commonly used tire sizes installed on Highway Department trucks and sedans will be evaluated. Major manufacturers and other manufacturers (later defined) products will be studied to determine average service life. One half or four highway districts (1, 2, 7 and 8) will be involved in the project and the trucks used will be selected or assigned at random in these districts (The sedans used in the study will be Central Office pool vehicles). A progress record for each tire and use record for each vehicle with regular report or measurement times to be specified …

Limestone Fine Aggregate In Portland Cement Concrete, George R. Laughlin

Kentucky Transportation Center Research Report

Limestone is classified as a carbonaceous sedimentary rock. In general, the term is applied only to those rocks in which the carbonate fraction exceeds the non-carbonate fraction. The carbonate may be calcite and/or dolomite. In addition to the primary constituents, there are contaminating minerals such as quartz, clay minerals, chalcedony (chert and flint), pyrite, feldspars and organic matter. The clay minerals are probably the most deleterious contaminates in carbonate rock.

Investigation Of Concrete Pavement, Us 60 Between Versailles And Frankfort, William B. Drake

Kentucky Transportation Center Research Report

A preliminary examination was made of the subject pavement on November 2, 1959, by James H. Havens and the writer, of the Research Division, and J. S. Riley, Construction Division. The discover of deleterious matter in the pavement was the major reason for the inspection. Foreign objects could be found imbedded in the concrete pavement throughout the project. However, there were a great many more in two sections, each about one quarter of a mile long, than on the rest of the project. The objects observed were wood, cloth, metal and soil. However, there was decided prevalence of soil. The …

Morton’S Gap Culvert-Pipe Installation, James H. Havens

Kentucky Transportation Center Research Report

The attached report, "Interim Performance Report on Morton's Gap Culvert Pipe Installation", by James H. Havens, is primarily a listing of the status of the condition of pipe still in the test and the date of failure or removal of the other sections.

Mr. Havens has prepared as background information, a brief record of the Department's practices involving pipe use for the past 10 years. He has begun with the Research Division's first study into pipe damaged by the corrosive action of acid water. This information is presented primarily because of its significance in the development of the culvert pipe …

Bituminous Concrete Pavement Surface Damage From Soil Action, James H. Havens

Kentucky Transportation Center Research Report

During the last week of August, Mr. J. S. Riley, Supervisory Construction Engineer, Area D, called our attention to a unique problem which arose during the final dressing of the most recent extension of the New Circle Road in Fayette County. Because of the uniqueness of the situation, the memo is intended to be a record of the phenomenon observed and a report of our investigation and analysis of the circumstances related thereto.
