Federal Aid Research Task No. 28: Pavement Failures: I-71 Oldham - Henry Counties, Clark Graves

Kentucky Transportation Center Research Report

Breaking and Seating has been used extensively to rehabilitate portland cement concrete pavements. In areas where specific vertical tolerances must be maintained, several methods have been used - - tapering of the asphaltic overlay, removal of the portland cement concrete replaced by full depth asphaltic concrete, or milling of the existing pavement and reducing the asphaltic concrete overlay.

Research Report UKTRP-87-26, "Breaking and Seating of Rigid Pavements" was prepared as a final report for three studies and as an interim report for Federal Aid Research Task No. 28 and two other studies. This report serves to finalize Federal Aid Research …

Performance Of A Shrinkage Compensating Deck Concrete (Ky 1974 Bridge Over West Hickman Creek), David Q. Hunsucker

Kentucky Transportation Center Research Report

This report summarizes performance monitoring activities and evaluation in conjunction with the experimental use of shrinkage compensating bridge deck concrete (Class s). Two bridges of similar design but constructed using Class AA concrete were monitored for comparison purposes. due to the absence of significant shrinkage cracking on the comparison bridge decks and the presence of minor shrinkage cracking on the Class S bridge deck, no conclusions were apparent at this time. Further study may quantify the reduction of shrinkage cracking due to the use of shrinkage compensating concrete in bridge decks.

Modular Expansion Joints And Deck Drains, Theodore Hopwood Ii, Edgar E. Courtney

Kentucky Transportation Center Research Report

Inspections were conducted on bridge modular expansion joints and deck drains to assess their performance. Forty-four modular expansion joints were inspected including 38 Wabo-Maurer and 16 Acme joints. Twenty-three elastomeric dams were also inspected for comparative purposes including 21 Transflex dams and 2 Fei-Span units. The joints were rated using a quantitative subjective rating system developed by Penn DOT.

Both the modular expansion joints and the newer expansion dams were performing satisfactorily. Both types of joints leaked and experienced a number of minor hardware problems. some of the joints may warrant repairs to restore their complete function.

Deck drains and …

Evaluation Of Construction-Zone Pavement Marking Materials, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

The objectives of this study were to evaluate available foil-back and removable tapes as well as one new construction-zone raised pavement marker and to recommend materials that should be included on approved lists for use by the Kentucky Department of Highways. Tapes were placed on transverse test sections and the reflectivity, durability, and appearance were observed.

Tapes to be included on the approved lists for foil-back and removable tapes were recommended. Tapes manufactured by 3M, Flex-0-Lite, and Swarolite were included on the list of acceptable foil-back tapes. Recommended removable tapes were the 3M and Cataphote removable tapes. The Astra Optics …

Lead In Your Drinking Water, Joseph L. Taraba

Agricultural Engineering Extension Updates

The U.S. Environmental Protection Agency (USEPA) recently imposed a regulation requiring public water suppliers to notify all their customers of the potential health effects of lead from household plumbing. The USEPA regulates public water supplies (with at least 15 service connections or servicing 25 individuals) but does not regulate private water supplies. The potential health hazard of lead is also present from household plumbing which is supplied water from a private water source.

Bottled Water, Joseph L. Taraba

Agricultural Engineering Extension Updates

Bottled water is an option for families who have a water problem, whether their water is unsafe or has an "off" taste or odor. It is best used as a temporary measure or in small quantities for drinking water. At a cost of 65 cents to $1.15 per gallon (Lexington, KY; July 1988) bottled water could become an expensive item for a large family using it for drinking and cooking.

Interim Guidelines For Design Of Highway Pavements, Gary W. Sharpe, Ronald D. Hughes, David L. Allen

Kentucky Transportation Center Research Report

The adequacy of a pavement design is directly related to the accuracy of traffic data, axle load information and materials data. It is assumed that appropriate construction procedures will be employed and that the pavements will be maintained periodically during the course of their service lives.

It is assumed that the subgrade will be constructed at or near the optimum moisture content and to the maximum dry density as specified in appropriate standard specifications. It is also assumed that the base course materials meet design requirements, that the aggregates will meet soundness and durability requirements and that the aggregate base …

Activated Carbon Filters, Joseph L. Taraba, Linda Heaton, Tom Ilvento

Agricultural Engineering Extension Updates

Many people feel the water supplied by public water systems to their home faucets is not safe. Most people judge the quality of their water by taste, odor and appearance. But the risk to one's health cannot be judged by these factors. Many of the chemicals or biological organisms that affect one's health are tasteless, odorless and cannot be seen. In searching for a means to improve the safety to their drinking water they encounter water filters, water purifiers, activated carbon (AC) filters that are common names for home drinking water treatment devices. In reading the labels, boxes and instructions …

Portable Curing Frame, George B. Day V, Larry G. Wells, Timothy D. Smith, Ira J. Ross

Biosystems and Agricultural Engineering Faculty Patents

A portable curing frame is provided particularly adapted for use with an automated tobacco harvester. The curing frame includes a substantially rectangular frame member including a series of slotted tracks, in the form of slotted tubes, specially designed for receiving a notched portion of the plant stalks. The slotted track is substantially continuous and thereby allows infinitely variable spacing between the plants and optimization of ventilation for air curing. Legs are also provided on the portable curing frame. The legs are displaceable between a retracted position allowing storage of the frames and loading of the frames with tobacco plants and …
