Use Of Preformed, Compressed, Neoprene Seals In Joints Of Concrete Bridge Decks, Ronald D. Hughes

Kentucky Transportation Center Research Report

Two types of seals are proposed for installation in contraction and construction joints in Ramp A, Ramp B, and the Main-Line structures from Third Street to Preston Street on Project I64-2(24)4, Jefferson County. The majority of contraction and construction joints are to be sealed with the preformed, compressed, neoprene seals. Specific joints in each structure will be sealed with cold-applied, elastomeric-type, joint-sealing compound; and these will be used as control joints for evaluation of the preformed, compressed, neoprene seals. Installation of all seals will be observed, and inspections will be made periodically. The performance of mastic-type sealants in joints in …

Kentucky Rock Asphalt, Traffic-Bound Bases, George R. Laughlin

Kentucky Transportation Center Research Report

Kentucky rock asphalt (a medium-grained quartz sandstone impregnated with natural bitumen) occurs as major deposits in Edmonson, Grayson, Hardin, Breckinridge, Logan and Warren Counties. Physiographically these deposits occur along the southeastern margin of the Western Coal Field. Geologically the Caseyville formation (particularly the Bee Spring member) of the Pottsville series of the Pennsylvania strata and the Hardinsburg and Cypress sandstones of the Middle Chester series of the Mississippian strata are of interest. The areal geology of Kentucky is shown in Figure 1 and the locations of rock asphalt deposits are depicted in Figure 2.

Performance Of Initial Treatments, Constructed During 1963, James H. Havens, Robert L. Florence

Kentucky Transportation Center Research Report

Seventeen initial bituminous treatment projects were advertised for bids during 1963, which permitted bituminous concrete Class I Surface (hot-mix) as an alternate to Class C-1 Surface (road-mix). The hot-mix surface course was to contain a minimum of 6 percent PAC-9. Eleven of the contracts, totaling 38.841 miles in length, were awarded as hot-mix; and the remaining six contracts, totaling 18.12 miles in length, were awarded as road-mix.

Final Construction And Interim Performance Report: Experimental Use Of Thermoplastic Pavement-Striping Materials, James H. Havens, John W. Scott

Kentucky Transportation Center Research Report

The purposes and objectives of this 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-pile 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) submitted September …

Weighing Vehicles In Motion [1964], College Of Engineering, University Of Kentucky

Kentucky Transportation Center Research Report

This report describes the construction, installation, testing and performance analysis of three types of dynamic electronic scales; the Taller-Cooper, a commercially developed four load cell scale, the Broke Bridge, an adaptation of a German prototype employing two load cells and the Bean Type Scale, an experimental prototype that uses a pair of instrumented aluminum beams as the weight sensors.

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 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 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 …

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 …
