A Laboratory Investigation Of The Properties Of Coal-Bitumen Paving Mixtures, Gary Grant Howard

Kentucky Transportation Center Research Report

The principal objective of this study was to investigate the feasibility of using coal, and to a lesser extent coal mine wastes, as aggregate in bituminous paving mixtures. These local aggregates were laboratory tested in bitumen-aggregate mixtures and, more particularly, in so-called cold-mixes. The bitumen-aggregate mixtures were evaluated by the Immersion-Compression Test, ASTM D 1075-60, with modifications for cold mixtures recommended in the Public Roads Journal (4).

In this initial study, since it was not possible to evaluate all types of mixtures, the primary question of whether coal and its waste products can be used as road aggregate could not …

A Study Of The Effects Of Quick Freezing On Saturated Fragments Of Rocks, John W. Scott, George R. Laughlin

Kentucky Transportation Center Research Report

Quick freezing of a fragment of rock which is fully saturated with water is, perhaps, the most rigorous of all tests for soundness, durability, or resistance to weathering. So-called soundness or quality tests employed currently, or heretofore, for evaluating concrete aggregates are usually less rigorous inasmuch as the state of saturation at the outset of freezing is not at a critical level. Hence, the number of freeze-thaw cycles endured by a rock specimen undergoing freezing and thawing in the presence of available water may merely reflect the duration of the exposure before the rock becomes vulnerable to damage -- i.e., …

A Rheological Investigation Of Asphaltic Materials, W. A. Mossbarger Jr.

Kentucky Transportation Center Research Report

Asphalts, serving as cements or binders in bituminous pavements, behave essentially as purely viscous, mobile, liquids at high temperatures and assume varying degrees of viscoelasticity, plasticity, elasticity, etc., upon cooling. They stiffen to a semi-solid state at cold temperature and do not. exhibit a discrete melting or freezing point, Saal (1)* classifies bitumens into three types according to their rheological properties at normal temperatures. They are: 1) those which behave entirely or almost entirely like Newtonian liquids, 2) those which show elastic effects during initial deformation and which exhibit Newtonian flow thereafter, and 3) those which show almost complete resilience …

Fourth Annual Performance Survey Of Reinforced Concrete Pipe Culverts, Ronald D. Hughes

Kentucky Transportation Center Research Report

A stylized, rational criterion for the structural design and installation of reinforced concrete pipe culverts was developed by the Bureau of Public Roads in cooperation with Prof. M. G. Spangler of Iowa State College and the American Concrete Pipe Association and was distributed to the various state highway agencies, April 4, 1957, as Circular Memorandum 22-40.* The criterion was intended to bring together and simplify methods for computing the strengths required for various fill heights and conditions of bedding. The several highway agencies were urged to adopt the criterion for use on all Federal-aid projects and accordingly, the Kentucky Department …

Status Report On Landslide Area On I-75, Covington, Kentucky [August 1963], Robert C. Deen

Kentucky Transportation Center Research Report

This report has been prepared to describe the conditions of the landslide area on Interstate Route I-75 in Covington, Kentucky, since May 15, 1963, the date of an earlier status report. Subsurface data which has been collected and assembled during the past three months is also included. Possible corrective considerations have also been included in this report.

The rainfall data included in this report, as well as the previous status report (May 15, 1963), are the official 24-hour precipitation recorded by the U. S. Weather Bureau at the Greater Cincinnati Airport in Boone County, Kentucky. The airport is located approximately …

Interim Report On Rural Secondary, Base Stabilization Projects, Robert C. Deen, J. D. Shackelford

Kentucky Transportation Center Research Report

Early in 1962, the Division of Rural Highways selected several base stabilization projects for construction during the 1962 season. These projects were to involve the addition of 1-1/2 to 3 inches of compacted granular base to existing, rural secondary, traffic-bound macadam roads. Since these roads were not intended to be surfaced, calcium chloride and sodium chloride were to be added to the additional granular base material in an attempt to retain or "hold" the aggregate on the road. This treatment was in tended to improve the road and to build up the base over a period of a few years …

Status Report On Landslide Area On I-75, Covington, Kentucky [May 1963], Robert C. Deen

Kentucky Transportation Center Research Report

This report has been prepared to describe the history and present condition of a landslide area on Interstate Route I-75 in Covington, Kentucky, This landslide is one of several to be studied as part of a research project on the "Development of a Practical Method of Locating and Tracing Seepage Water in Unstable Slopes. " On April 10, 1963, a request was submitted to the Bureau of Public Roads to change the Work Program HPS-1(24) to include this research project. Approval was received on May 2, 1963. Work done on this research project prior to May 2 was at Department …

Experimental Use Of Thermo-Plastic Pavement-Striping Materials, James H. Havens

Kentucky Transportation Center Research Report

The purposes and objectives of this experimental study are: 1) to evaluate the application and performance characteristics of hot-melt plastic, pavement-striping materials which are presently prominent and known commercially as "Catatherm" and "Perma-Line"; 2) to compare the performance of these materials with the performance of painted stripes applied and re-newed according to the current practices of the Kentucky Department of Highways; and 3) to evaluate the economics of these striping materials in terms of cost-per-mile per-day-of-useful-life, The project is described more fully in the "Proposal... " (approved by Division Engineer, September 7, 1962) and in Report No. 1 (Pre-Construction Report) …
