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 …

Irrigation And Drainage Problems In Uruguay, Jerald Emmet Christiansen

Reports

Synopsis: Uruguay irrigates about 65,000 acres, mostly rice (74%) and sugar cane (15%). Summer rainfall averages about 3.5 in. per month, but frequent droughts seriously affect both crops and livestock. Irrigation can be increased by storage in small reservoirs on tributary streams by means of low earth dams. Some areas will require flood control and draiange before intensive agriculture can be practiced.

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 …

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 …

An Evaluation Of The Beggs Deformeter In Two-Dimensional Structural Analysis And An Investigation Of The Deformeter In Three-Dimensional Structural Analysis, Dwight F. Denton

Civil Engineering ETDs

It was the purpose of this thesis to evaluate the Beggs deformeter in two-dimensional structural frames and then investigate the possible use in three-dimensional structural frames. It is intended in dealing with the subject to explain and describe the deformeter apparatus and verify the theoretical principle through actual structural model analysis.

An Investigation Of The Effects Of Pozzolans On New Mexico Concrete Aggregates, Harry W. Montgomery

Civil Engineering ETDs

It was the purpose of this investigation to determine some of the effects a pozzolan has on Portland cement concrete when New Mexico aggregates are used. The specific items investigated were (1) to determine the effects of a pozzolan on the alkali aggregate expansion in concrete; (2) to show the effect on the compressive strength of concrete and the tensile strength of mortar briquettes when part of the Portland cement is replaced with a pozzolan; (3) to determine whether or not the “Mason Jar Expansion Test” would give reliable results; and (4) to determine whether or not an aggregate, with …

Dust Control On Unpaved Roads - A Review Of Literature, D. G. Shurig

Indiana Local Technical Assistance Program (LTAP) Publications

This review summarizes literature on available materials, their application, costs and relative effectiveness for laying road dust. The review was authorized by the HERPIC Board on August 27, 1959 for the purpose of assisting officials in controlling road dust on county roads.

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).

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.

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 …

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 …
