Acoustic Emission Monitoring Of In-Service Bridges, Theodore Hopwood Ii, David W. Prine

Kentucky Transportation Center Research Report

An experimental acoustic emission (AE) device, the GARD Acoustic Emission Weld Monitor (AEWM), has been field tested on six bridges during this study. In addition, the device was used to test three other bridges under separate contracts from state highway agencies. The device was evaluated to determine if it could detect fatigue-crack growth on in-service steel bridges.

The AEWM employs a proprietary three-step model (filter) to reject noise-related AE activity and detect and locate defects subject to varying stress conditions. The unit uses built-in microprocessors to compare incoming data to the model. If defect-related AE activity is detected, the AEWM …

Implementation Of A Pavement Management Program In Lexington-Fayette County, Kentucky, Gary W. Sharpe, Robert C. Deen, Ronald R. Sewell

Kentucky Transportation Center Research Report

Lexington, in central Kentucky, is the second largest city in the state. Local government is by a mayor and council of elected representatives from twelve districts and three at-large representatives. The Department of Public Works headed by a Commissioner, who reports to the mayor and city-county council, administers the streets and roads system.

The street and road network in Lexington consists of approximately 720 centerline miles. Approximately 100 miles are rural in nature and 620 miles are urban. Approximately 95 percent are bituminous surfaced roads; a majority of the remainder is constructed of portland cement concrete.

Increasing costs for constructing …

Performance Evaluation Of Breakaway-Cable-Terminal End Treatments, Jerry G. Pigman, Kenneth R. Agent

Kentucky Transportation Center Research Report

This report included an analysis of 110 accidents involving breakaway-cableterminal (BCT) end treatments and 36 accidents involving median-breakaway-cableterminal (MBCT) end treatments as used in Kentucky. The primary data base consisted of Kentucky accident records for the years 1980-87; with a few accidents that were identified before 1980. An attempt was made to document each accident with a police report, photographs, and a maintenance repair form.

Results revealed that the breakaway-cable-terminal end treatment performed properly in 73 percent of the accidents when all three configurations of end treatments were combined (simple curve, parabolic flare, and straight). Proper performance was defined as …

Allocation Of Resurfacing Monies To Highway Districts In Kentucky, Rolands L. Rizenbergs, Robert C. Deen

Kentucky Transportation Center Research Report

Allocation of resurfacing and rehabilitation monies began in 1967 with the separate funding of a resurfacing program. Pavement projects for resurfacing and rehabilitation were selected more often than not on the basis of politics and arbitrary (i.e., without the benefit of analysis of good inventory and condition data) judgments of decision makers. With the gradual introduction of more adequate roadway inventory and annual condition data, the formula for the allocation of funds has been gradually revised, updated, and improved so there is now a more logical and equitable distribution of funds.

With the formation of a pavement management staff in …

User's Guide For Pavement Condition Surveys, Gary W. Sharpe, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

The pavement condition survey is a visual inspection of the travelway of a street/road system. The survey provides measures to assess the magnitudes of various types of pavement distress. The rater is not to make evaluations on the basis of known or suspected subsurface conditions. It is necessary the rater only report in an objective manner what is seen. The types of distress include the following:

For Asphaltic Concrete Pavements: Alligator Cracking, Block/Transverse Cracking, Reflective Cracking, Rutting, Raveling, Bleeding, Surface Irregularities (shoving, corrugations, potholes), and Patching/Utility Cuts.

For Portland Cement Concrete Pavements: Blowups, Spalling and Popouts, Map Cracking, Longitudinal Cracking, …

Evaluation And Application Of Roadway Marking Materials, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

Three different areas of roadway delineation were included in this study. These areas were:

1. Lane delineation materials,
2. crosswalk delineation materials, and
3. snowplowable markers.

Evaluation of lane delineation materials revealed that expanded use was warranted for polyester paint and extruded thermoplastic. The alkyd-resin extruded thermoplastic material was determined to be the most cost-effective material for crosswalk and stop bar installations. Durability and reflectivity results show that Stimsonite 96 markers have performed effectively as snowplowable markers while the recessed markers have performed effectively except on certain interstate locations.
