Bond Characteristics Of Commercial And Prepared Reinforcing Bars, S. T. Collier

Kentucky Transportation Center Research Report

Early in 1945 a request was made by the Bridge Division of the Kentucky Department of Highways that bond characteristics of certain reinforcing bars be analyzed by the Department's Materials Research Laboratory. Nothing extensive was contemplated, it being the intent of the Bridge Division to determine whether reinforcing steel commonly used on bridge projects at the time should develop bond stresses reasonably close to those that could be developed by the specially prepared bars; and if not, whether the special bars produced benefits commensurate with increased costs.

Five types of bars were selected, and pull-out tests in preference to beam …

Experiments With Pressure Methods Of Air Content Determinations For Cement Concrete, L. E. Gregg

Kentucky Transportation Center Research Report

In our report entitled "A Summary of Experiments With Air Entrainment in Cement Concrete" released last September, we recommended among other things that "The gravimetric method (A.S.T.M. Designation: C138-44) be used only as a temperary expedient for determining air contents until the pressure method or some method not dependent upon physical properties of aggregates and not influenced by other variables can be firmly established" (see item 3, page 66 of that report). At that time we were thinking of the pressure apparatus demonstrated by representatives of the Portland Cement Association during construction of the Lexington-Nicholasville Road (Project F 524 (1)-1; …

A Comparison Of The Use Of Polaroid And Colored Filters In The Multiplex Aeroprojector, Robert Greig Livingston

Masters Theses

"The purpose of this thesis is the drawing of a comparison between the use of the colored filters, which are normally employed in the multiplex aeroprojector by various mapping agencies throughout the country, and the use therein of Polaroid filters. The filters in the aeroprojector serve to break the projection of a stereoscopic pair of photographs into two impressions which are viewed separately by each eye of the observer, thus providing the main requirement for the observance of a three-dimensional effect. this stereoscopic effect is utilized in the multiplex plotting machine for the delineation of contours...In order to form a …

A Summary Of Experiments With Air Entrainment In Cement Concrete, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Field and laboratory experiments designed to show the merits of air-entrainment in cement concrete have been conducted by the Department of Highways since 1940. During that time six laboratory projects with many variables have been completed, and most of these were directly related to the four experimental roads which have been in service from four to six years. Collectively these experiments form a moderately comprehensive analysis of the features of air-entrainment, still there are many points which have not been fully covered either because of limitations in time and personnel or because of new developments which render some of the …

Porous Backfill, Robert F. Baker

Kentucky Transportation Center Research Report

Until the late 1930's, the accepted practice for the construction of drainage installation included the use of a large, approximately No. 2 size, aggregate as porous backfill. However, a lage number of drains ceased to function as result of clogging or "silting"*, and many highway departments practically eliminated sub-surface and intercepting drainage.

The following report summarizes some of the more important studies that have dealt with "filter" (backfill material) to be used in drainage construction. The scope of it is limited, dealing primarily with the questions of proper gradation.

At present Kentucky Specifications (1) require that the gradations of the …

This project is more or less a preliminary investigation of Tennessee River gravel relative to the effect of the moisture condition of the aggregates upon the durability of concrete. Certain observations made in the field indicated that absorbed moisture in the aggregate could have a marked effect on concrete, so this study was made in an attempt to give quantitative significance to the observation.

Proposed Field And Laboratory Study Of Flexible Pavements, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Research into the problem of the design and control of flexible pavement construction has resulted in the use of empirical and arbitrary solutions consisting of general theories for determining pavement thickness, gradation of aggregate, percent of bitumen, base requirements, etc. A desirable method would be one that is applicable to all aggregate, bitumen, and subgrade conditions. Until such a procedure is available, a determination of existing procedures are the immediate problems of highway engineers.
