17-Year Report On The Owensboro-Hartford Co-Operative Investigation Of Joint Spacing In Concrete Pavements, Milton Evans Jr., William B. Drake

Kentucky Transportation Center Research Report

In 1940, the Kentucky Department of Highways constructed an experimental concrete pavement which was one of a group of six built in co-operation with the Bureau of Public Roads by the States of Minnesota, California, Kentucky, Michigan, Missouri and Oregon. The purpose of these projects was to study and evaluate the performance of such pavements over a period of years with specific regard to types of joints and spacings. The Kentucky project, consisting of 6.27 miles, was constructed in Daviess County, beginning approximately 6 miles south of Owensboro on US Route 231 (formerly Ky. Route 71).

Re-Evaluation Of The Kentucky Flexible Pavement Design Criterion, William B. Drake, James H. Havens

Kentucky Transportation Center Research Report

Prior to 1948, the criterion in Kentucky for designing the thickness of bituminous pavements was based upon a modified laboratory CBR and the 1942 curves developed by the California Department of Highways. In 1948, the Materials Research Laboratory reported: "An Investigation of Field and Laboratory Methods for Evaluating Sub-grade Support in the Design of Highway Flexible Pavement." Included in that report as a recommended method of thickness design for use in Kentucky was a set of curves based upon an empirical relationship between minimum laboratory CBR and observed pavement performance. These five curves accounted for traffic groups up to 10,000,000 …

Bridge Resurfacing With Silica Sand-Asphalt Mixture, Loren H. Strunk

Kentucky Transportation Center Research Report

The bituminous section has been engaged in testing silica sand-asphalt mixtures composed of various penetration grades of asphalt and sands from sand and sandstone deposits from several different areas of the state since early this year. The purpose of this study was to develop a surfacing mixture which would provide a skid-resistant surface and which could be machine laid in thin courses.

Skid Prevention Studies In Kentucky, James H. Havens

Kentucky Transportation Center Research Report

Laboratory apparatus, consisting essentially of a torque generator and a torque meter, in which a rubber annulus is driven against a plane surface of a rock core or pavement specimen, as in an ordinary friction clutch, was used to study variations in the coefficients of friction with respect to texture and material characteristics. Dry friction coefficients were found to be rather high in magnitude. and fairly constant throughout wide variations in surface textures. In contrast, wet friction coefficients were very high for rough textures but very low for polished surfaces. Wet friction values correlated in an approximately hyperbolic manner with …

Differential Thermal Analysis Of The Freeze-Thaw Mechanisms In Concrete, James H. Havens, Knox R. Burchett

Kentucky Transportation Center Research Report

The freezing of water in concrete may create highly disruptive internal forces, depending upon the degree of saturation of the voids and the extent of the resulting dilations. Heretofore, it has not been possible to measure the internal pressures accompanying freezing; and it is this aspect of the automatic freeze-thaw testing of concrete with which the present study was concerned. By the use of thermocouples, imbedded in concrete and referenced to an ice-water bath, it was possible to plot, on an automatic multivolt potentiometer recorder, an isothermal phase change for the absorbed water, and to demonstrate a depression of the …

Recommendations For Special Specifications, Covering Basic Lead Silico-Chromate, Oil-Alkyd, Vinyl-Alkyd Paints For Bridges, James H. Havens

Kentucky Transportation Center Research Report

This specification covers the material requirements for a Basic Lead Silico-Chromate, Oil-Alkyd Paint System intended for use on exterior iron and steel structures (bridges), for either new or re-paint work, except where exposed to severely corrosive conditions such as within the splash-zone from bridge decks or on other members likely to be affected by de-icing salts or persistent moisture conditions. This system shall consist of a primer-, intermediate-, and finish-coat paint as hereafter specified. Uses of the component paints other than as an integral part of this system are specifically excluded.

An Evaluation And Summary Of The 16-Year Performance Of A Concrete Test Pavement, Milton Evans Jr.

Kentucky Transportation Center Research Report

Presented herein are a summary and evaluation of the performance of a reinforced concrete section of U.S. 27 in north central Kentucky which has been in existence since the summer of 1941. The pavement, totaling 7.89 miles, was constructed in 10 experimental test sections, as shown on the layout map in Figure 1. Five blends of cement, containing normal portland, natural, and two additives, were used with two types of coarse aggregate, limestone and gravel. Since the construction of the pavement in the summer of 1941, several reports and memoranda have been released dealing with various aspects of the over-all …

A Study Of The Use Of A Local Fly Ash In Concrete Mixes, Frank D. Whitney

Kentucky Transportation Center Research Report

The widespread use of powdered coal in industrial furnaces has, since its introduction in the 1930's, produced considerable increases in efficiency for many industrial processes. In its wake, however, it has brought its own unique problems, and chief among these has been the problem of collecting and disposing of the residue which results from the combustion of the powdered or ground coal. This residue, known commonly as fly ash, is a nuisance if it is allowed to be dispersed into the atmosphere; and if collected it presents a difficult disposal problem. In present industrial practice it is almost always collected, …
