An Installation Of An Experimental Joint For Concrete Pavements, Harvey J. Field Jr.

Kentucky Transportation Center Research Report

The experimental joint described in this paper involves the use of a new type load transfer set-up which was developed by the Oxford Manufacturing Company, Oxford, Indiana, and produced by the Reynolds Metals Company. The producers designed this apparatus on the assumption that the present joints used in concrete pavement construction are not adequate. For example, from the standpoint of load bearing, the dowel bars which theoretically carry the load from one slab to the other are not sufficient in that the very shape of the bars (circular) allows only a limited bearing surface. In order to eliminate the rusting …

Determination Of Unit Weights Of Aggregates In The Laboratory And At The Source, S. T. Collier

Kentucky Transportation Center Research Report

As a result of meetings with producers, a committee of Highway Department engineers recommended that a study be made of various type of aggregates from statewide sources; the objective being to arrive at a standard of evaluating unit weight of aggregates of various but commonly recognized characteristics. It was further desired that a factor be determined which could be applied to a given aggregate for computing its unit weight with reasonable accuracy; taking cognizance of specific gravities and densities as influenced by particle shapes and gradation.

Prefabricated Neoprene Joint Sealer, A. C. Peed Jr.

Kentucky Transportation Center Research Report

On November 18, 1948, the assembly of joints with prefabricated neoprene sealers was demonstrated by representative of the Lastite Joint Company, 105 W. Madison Street, Chicago 2, Illinois, on the construction project on U.S. 27, about 5 miles south of Alexandria. Installation was not possible at that time due to the fact that the contract was temporarily without cement.

Installation was made on November 30, 1948, under the supervision of a representative of the company. This installation was not completely satisfactory due to the inexperience of the paving crew with this type of joint. The joint at Station 622÷22 was …

Measurement Of Surface Irregularities And Riding Qualities Of High Bituminous Pavements, Harvey J. Field Jr.

Kentucky Transportation Center Research Report

This report covers work completed up to the present time on the measurement of irregularities affecting the riding qualities of high type bituminous Pavements. The largest portion of this study was devoted to new construction involving Class I, Plant Mix Bituminous Concrete pavements although other roads were studied on the same basis for comparison purposes.

The purpose of the project was to evaluate the roughness characteristics of high type bituminous pavements by measuring the surface irregularities and interpreting them in terms of existing specifications. In evaluating these pavement irregularities two methods were used; one with which the surface was actually …

Some Chemical, Physical And Mineralogical Features Of Soil Colloids, James H. Havens, James L. Young Jr., William B. Drake

Kentucky Transportation Center Research Report

The -1 micron portion of several diversified soils were separated by sedimentary fractionation. Physical properties were evaluated on the -1 micron portion, the +1 micron portion, and on the original -40 sample. The -1 micron portion was analyzed for clay mineral identity by X-ray diffraction, and analyzed chemically for associated materials such as the oxides of Iron, Aluminum, Calcium, and lv!agneeium.

These data present several possibilities and trends as to the inter-dependency of the involved variables, other considerations have been devoted to the geologic origin of several samples and to various physico-chemical relationships.

Concrete Pavement Without Transverse Joints, William B. Drake

Kentucky Transportation Center Research Report

This is a report of observations and operations pertaining to a concrete pavement without the usual transverse joints constructed during the summer of 1949.

The project which is on U. S, 31-W is designated as Simpson County, FI-239 (4), and runs from Station 9+11 at the Tennessee State Line to Station 311+40 at the city limits of Franklin (See Fig. 1 for layout). It consists of a 22-foot concrete pavement underlain by 1-1/2-inches of compacted crushed limestone (Size No. 10) for insulation and leveling. The slabs are of air-entrained concrete made with the agent interground in the cement, There is …

A Study Of The Effect Of Blended Coarse Aggregate On Air-Entrained Concrete Progress Report 3, S. T. Collier

Kentucky Transportation Center Research Report

The purpose of this investigetion was to study the durability characteristics of a river gravel, used as coarse aggregate for concrete, with respect to four major fractions separated in accordance to their general mineralogical classification. This aggregate was from the same stock of Ohio River gravel that was used in earlier phases of this Project reported in 1947.

Since this gravel consisted of several rock types varying in mineralogic constituents, it was conceivable that poor performance could possibly be attributed to some undesirable fraction or fractions, rather than to the aggregate as a whole. The separation of this aggregate was …

Cooperative Investigation Of Joint Spacing In Concrete Pavements, S. T. Collier

Kentucky Transportation Center Research Report

During the summer of 1940 the Kentucky Department of Highways, with the Public Roads Administration participating, constructed 6.27 miles of investigational pavement as a cooperative research project on joint spacing. This project was one of six planned by the Public Roads Administration and the Portland Cement Association in cooperation with six highway departments. The five other states participating were California, Michigan, Hinnesota, Missouri, and Oregon. The project selected for this jointing study in Kentucky is in Daviess County, approximately six miles southeast of Owensboro, on Kentucky Route No. 71 (Layout map in Figure 1).

The experimental program was outlined for …
