Stress Measurements On The I 65 Bridge Over The Ohio River At Louisville, Theodore Hopwood Ii, Christopher M. Oberst

Kentucky Transportation Center Research Report

Kentucky Transportation Center personnel conducted measurements of live stresses on structural members of the I 65 (John F. Kennedy Memorial) Bridge over the Ohio River. That work was performed in conjunction with an extensive flaw evaluation of the bridge by Hazelet & Erdal Consulting Engineers.

The measurements were performed by placing strain gages on the upper chord (an H-beam) and a vertical post and transverse strut that were framed into the upper chord at PP63 on the West truss. Measurements were performed using battery-powered data logging instruments that were capable of unattended strain measurement. The units were used to monitor …

Evaluating The Design And Effectiveness Of Subsurface Drainage Layers, Bobby W. Meade, David Q. Hunsucker

Kentucky Transportation Center Research Report

In recent years, the subject of open-graded drainage layers, often referred to as "drainage blankets", has been utilized increasingly for pavement drainage. This study addresses the use of drainage blankets in Kentucky. Study efforts have focused on construction, performance, materials, and design considerations of drainage blankets.

Study findings are that the Number 57 gradation provides the optimum drainage and structural stability of the standard gradations evaluated. Asphalt treated aggregate provides greater stability and a better working platform than untreated aggregate. Maintenance of collector system outlets is very poor. Daylighting of drainage blankets appears to be feasible. Drainage blankets can be …

Evaluation Of Kentucky’S Policy On Tourist Information Signs, Jerry G. Pigman

Kentucky Transportation Center Research Report

As a result of recommendations made by the Governor's Task Force on Signage and Tourism, the Transportation Cabinet requested that an evaluation be made of Kentucky's policy on tourist information signs. Among the tasks undertaken were a review of the formula tor Parks, Historic, and Recreation Area signs, a survey of interstates and parkways to determine the extent of the constraints imposed by the limitation of one supplemental sign tor each interchange approach, and an investigation of the potential for application of Tourist Oriented Directional signs (TODS).

The opportunity tor increased tourism through improvements in signing and accessibility was evaluated. …

Summary Of Stress Evaluations Of Welded Steel Bridges On Coal-Haul Routes, Theodore Hopwood Ii, Keith J. Hogan, Christopher M. Oberst

Kentucky Transportation Center Research Report

Stress analyses were performed on continuous girder welded steel bridges on extended weights coal-haul routes. The tests were intended to determine whether extended weight coal trucks pose fatigue problems to those bridges. Measurements were performed by strain gaging selected bridges subject to high coal transport tonnages. Stress measurements were conducted on fatigue-prone weld details or test sites where high tensile stresses were anticipated. Test sites on the bridges were instrumented with strain gages. Strains induced by routine traffic including coal trucks were monitored for periods of one to two weeks. Unattended monitoring of the variable amplitude strain data was performed …

Cost Estimating And Forecasting For Highway Work In Kentucky, James D. Stevens

Kentucky Transportation Center Research Report

There is a need for a better cost estimating and forecasting for highway work in the Commonwealth of Kentucky. KRS45.245 grants the Interim Joint Committee on Transportation oversight of the biennial highway plan, including a review of all authorized highway project phases that exceed their estimates by 15%. In recent years, the Kentucky Transportation Cabinet has suffered the loss of many resources necessary to produce good cost estimated.

Estimates developed using current methods are not sufficiently accurate to preclude cost overruns in excess of 15%. During the biennium 134 overruns, totaling over $69 million, have been submitted to the Committee. …

Construction And Interim Performance Of A Shrinkage Compensating (Class S) Bridge Deck Concrete, Michael D. Stone, David Q. Hunsucker

Kentucky Transportation Center Research Report

Shrinkage Compensating Concrete (Class S) is made with an expansive cement in which the expansion, if restrained, induces compressive stresses that approximately offset tensile stresses induced during drying shrinkage, thereby eliminating or significantly reducing the occurrence of shrinkage cracking in concrete. The objectives of this study were to evaluate the construction and performance of the Shrinkage Compensating Concrete (Class S) and to compare these characteristics to previous Class S concrete data and to conventional Class AA bridge deck concrete. This report summarizes the construction activities and interim performance of experimental decks and barrier walls constructed of shrinkage compensating concrete.

Pesticide Application And Handling Technology: Installing A Sprayer Tank Rinse Circuit, G. A. Watkins, Samuel G. Mcneill, S. A. Shearer

Agricultural Engineering Extension Updates

Proper tank rinsing techniques for agricultural sprayers are very important in order to protect against cross-contamination in subsequent loads and to ensure safe disposal of any excess chemicals and rinsate (rinse water). Spray tanks and other sprayer components should be cleaned after each use. In most situations, sprayer rinsate will have to be sprayed out in the field - either onto a reserved strip, or by over-spraying in the treated area (subject to the terms of the product label).

Pesticide Application And Handling Technology: Proper Disposal Of Empty Pesticide Containers, G. A. Watkins, Samuel G. Mcneill, S. A. Shearer

Agricultural Engineering Extension Updates

Recycling has become more and more popular as our awareness of environmental concerns grow. These environmental concerns have led to increased participation in recycling efforts among today's farmers. Many farmers throughout Kentucky are now able to recycle their empty plastic pesticide containers (Five gallon or less) due to a statewide Rinse and Return program. Recycling of empty containers provides a safe means of disposal for applicators, reduces landfill space, and protects our valuable water resources.
