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; …

Outline Of Research For Adhesion Of Bituminous Materials To Mineral Aggregates, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

The primary object of this proposed research is to investigate existing procedures or develop new means for evaluating the adhesive capacity of bituminous materials when applied to mineral aggregates. This includes bituminous materials in combination with additives or so-called anti-stripping agents; hence, the scope of the project includes:

1. A study of aggregates for hydrophyllic or hydrophobic properties as related to different types of bitumen, and the selection of a standard aggregate by which the adhesion of bituminous materials themselves may be judged.
2. Comparison of grades and sources of bituminous materials with respect to power of adhesion to (or tendencies to …

Study Of The Effect Of Blended Coarse Aggregate On Air Entrained Concrete, S. T. Collier, L. E. Gregg

Kentucky Transportation Center Research Report

This research with combined coarse aggregates in cement concrete was initiated at the request of the Director of Design as a direct result of the condition study made by the Division of Design in 1945. In the report on this study it was shown that on the basis of averages pertaining to 80 projects with crushed limestone totalling about 395 miles in length, and 70 projects with Ohio River Gravel totalling approximately 410 miles in length, the service record for pavements with the river gravel was far inferior to that of pavements containing limestone coarse aggregate.

Specifically, the summary of …

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 …

A Study Of The Effect Of Blended Cements On The Durability Of Concrete Incorporating An Inferior Coarse Aggregate, S. T. Collier

Kentucky Transportation Center Research Report

Research Project C-13 was set up for the purpose of studying the effect of blended cement, with air-entraining properties, on the durability of concrete incorporating an inferior grade of limestone as the coarse aggregate. This investigation is not correlated with any Department of Highways field project, being entirely a laboratory study. The tests were begun April 12, 1945, and were completed February 6, 1946.

Durability Of Concrete As Affected By Absorbed Moisture In Tennessee River Gravel Aggregate, S. T. Collier

Kentucky Transportation Center Research Report

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.

A Proposed Study Of Soils As Related To The Pumping Of Rigid Pavements, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Pumping has been described as, "The process of ejecting the water-suspended subgrade soil from joints, cracks, and the edges of pavement caused by the deflection of the pavement slab under the action of traffic"(4)*. Obviously, the action is limited to rigid or semi-rigid pavements. Hence, the problem is largely concerned with soil and is almost entirely dependent upon properties of the subgrade. During the past five or six years pumping has become the most discussed if not the most important element of highway soils engineering largely because of the increase in heavily loaded vehicles resulting from wartime traffic requirements.

A Survey And Pedological Classification Of Kentucky Soils, Kentucky Highway Materials Research Laboratory

Study Of Proposed Specifications For Bituminous Coated Corrugated Metal Pipe, Robert F. Baker

Kentucky Transportation Center Research Report

On February 27 and 28, the author visited the Research Laboratories of the American Rolling Mills Company at Middletown, Ohio. The purpose of the visit was to investigate the technique and background of the new specifications for bituminous coated corrugated metal pipe as proposed by Armco with a view to changing the Kentucky Specifications (throughout this report "proposed specifications" will refer to the specifications recommended by the American Rolling Mills Company).

It is a rather evident fact, but the author wishes to point out that the short visit could furnish only an indication rather than a positive solution to the …

Outline Of Proposed Study Of Sands Used As Concrete Fine Aggregates, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

This investigation is being made for the purpose of evaluating fine aggregates for concrete in which the percentages of fines, finer than the No. 50 and the No. sieves, are increased over that in the normal commercial sands meeting the present specifications for Class "A" concrete. It is a continuation of the studies made in Research Projects C-14 and C-15 (Reports submitted January, 1946), but enlarged to include physical tests on sand, and tests on mortar specimens, as well as the usual tests on concrete specimens.

An Evaluation Of Density And Stability Tests On Bituminous Mixes, Cary Burns, L. E. Gregg

Kentucky Transportation Center Research Report

During the past three years the Highway Materials Research Laboratory has experimented with bituminous aggregate mixes in an attempt to determine the densities that can be obtained through certain methods of compaction and the stability of the resulting mixes. The several investigations have resulted in the preparation and testing of approximately six hundred individual samples, most of which were designed to provide information as a guide for specification on particular field projects.

Proposed Working Plan For A Study Of The Properties Of Coarse Aggregates, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Among the numerous materials used in the construction of highways probably none is more important or perplexing than coarse aggregate. Through past research and experience a group of procedures and specifications for selecting aggregates suitable for pavements has been developed. These acceptance tests deal almost entirely with physical properties such as gradation, soundness, absorption, abrasion, etc. However, recent data accumulated by field observations and surveys (1), (7), (8)* have indicated that some materials passing the specifications have undesirable properties which cause difficulties over a long period of time. Consequently, research directed toward a more thorough investigation of aggregates has become …
