Fatigue Analysis Of The I-75 Bridge Over The Kentucky River At Clays Ferry, Theodore Hopwood Ii, Vishwas G. Oka
Fatigue Analysis Of The I-75 Bridge Over The Kentucky River At Clays Ferry, Theodore Hopwood Ii, Vishwas G. Oka
Kentucky Transportation Center Research Report
Fatigue analysis was performed on AASHTO category E welded connections on the southbound I 75 bridge over the Kentucky River at Clays Ferry, Kentucky. That analysis was based on the stress-range histogram data provided by Law Engineering of Louisville, Kentucky. That data were obtained from strain gages installed at 6 test locations on the downstream truss.
The fatigue analyses consisted of safe-life and fatigue-crack growth analyses. Safe-life predictions were based on AASHTO fatigue design (SN) curves. To use those curves, equivalent constant-amplitude stresses were derived from the stress histograms. Those stresses and loading frequencies were modified to reflect anticipated increases …
Analysis Of Accident Data In Kentucky (1983-1987), Kenneth R. Agent, Jerry G. Pigman
Analysis Of Accident Data In Kentucky (1983-1987), Kenneth R. Agent, Jerry G. Pigman
Kentucky Transportation Center Research Report
Kentucky has a systematic procedure to identify locations that have abnormal rates or numbers of accidents. This procedure utilizes average accident rates and numbers. A primary objective of this study was to determine average accident statistics in Kentucky. An annual safety program for Kentucky, which includes the identification, programming, budgeting, and evaluation of safety projects, is prepared each year. The data presented in this report may be included as the problem identification portion of Kentucky's Annual Highway Safety Plan.
Average and critical accident rates were calculated by highway type for rural and urban highways. A summary of results and recommendations …
Impact Evaluation Of The Louisville-Shively-Jefferson County Traffic Alcohol Programs, Jerry G. Pigman, Kenneth R. Agent, Patricia L. Hardyman, Knowlton W. Johnson, Richard Mccleary
Impact Evaluation Of The Louisville-Shively-Jefferson County Traffic Alcohol Programs, Jerry G. Pigman, Kenneth R. Agent, Patricia L. Hardyman, Knowlton W. Johnson, Richard Mccleary
Kentucky Transportation Center Research Report
This report is an evaluation of alcohol enforcement programs conducted by the Louisville, Jefferson County, and Shively police agencies in the Louisville metropolitan area. The following four types of data were collected in order to evaluate the traffic alcohol programs; accident data, arrest and adjudication data, cost-effectiveness, and public opinion data.
Results from the before-and-after comparisons and time-series analysis show alcohol-related accidents decreased significantly during the study period, There was a 34.4 percent reduction in alcohol-related accidents during hours of special enforcement and a 30.4 percent reduction during all hours of the day. Time-series analysis of accident data showed a …
1988 Usage Rates And Effectiveness Of Safety Belts And Child Safety Seats In Kentucky, Kenneth R. Agent
1988 Usage Rates And Effectiveness Of Safety Belts And Child Safety Seats In Kentucky, Kenneth R. Agent
Kentucky Transportation Center Research Report
The objective of the survey summarized in this report is to establish 1988 safety belt and child safety seat usage rates in Kentucky to compare to those determined from previous surveys. Also included in this report is an analysis of accident records evaluating the effectiveness of safety belts.
Statewide usage rates in the 19 cities previously surveyed in 1982 through 1986 showed that both driver safety belt usage and child safety seat and safety belt usage increased significantly in 1988 compared to previous years. The statewide usage rate of safety belts by drivers was 20.5 percent in 1988 compared to …
Asphalt Surface Treatments For Local Roads And Streets, Ellis G. Williams
Asphalt Surface Treatments For Local Roads And Streets, Ellis G. Williams
Kentucky Transportation Center Research Report
Surface Treatments are thin applications of asphalt, with or without aggregate, to an existing pavement surface. There are many types to choose from when selecting a treatment for a specific purpose.
Because of the broad range of materials and methods available, surface treatments satisfy many needs in effective operation of road and street systems. They are major tools for preventive maintenance and also satisfy many corrective maintenance needs. They are widely and effectively used as the initial surfacing over granular bases. They are increasingly used over cracked, existing surfaces to reduce reflection cracking in asphalt overlays.
It is apparent that …
Calcium Nitrite As A Corrosion Inhibitor In Reinforced Concrete Bridge Decks, Theodore Hopwood Ii, David Q. Hunsucker, Edgar E. Courtney
Calcium Nitrite As A Corrosion Inhibitor In Reinforced Concrete Bridge Decks, Theodore Hopwood Ii, David Q. Hunsucker, Edgar E. Courtney
Kentucky Transportation Center Research Report
The use of calcium nitrite es a corrosion-inhibiting admixture in reinforced concrete hes been studied on two bridges· the Kentucky 152 Bridge in Washington County and the Gose Road Bridge in Boyle County. Calcium nitrite was added to concrete used in the slabs, diaphragms and barriers of the KY 152 bridge and only in the slab of the Good Road bridge.
Construction of both structures was monitored in the fall of 1986. Placement of concrete on both bridges was satisfactory; however, problems were experienced in finishing the concrete. The finishing problems were related to: 1) concrete 'stickiness', 2) use of …
Highway Safety Research, Development, And Technology Transfer, John A. Deacon
Highway Safety Research, Development, And Technology Transfer, John A. Deacon
Kentucky Transportation Center Research Report
Late in 1987, the Federal Highway Administration assembled a seven-member panel which, guided by a primary contractor, Harrison Boyd & Associates, was charged with the task of developing a recommended five-year research, development, and technology transfer program for highway safety starting in the 1990s. As a part of the task, each panel member prepared an individual position paper to stimulate and focus panel discussions and, ultimately, to provide the basis for a consensus paper. This represents one such individual paper.
Although it is believed that significant safety gains can be achieved in the 1990s and beyond simply by more extensive …
Comparison Of Rigid Pavement Thickness Design Systems, Herbert F. Southgate
Comparison Of Rigid Pavement Thickness Design Systems, Herbert F. Southgate
Kentucky Transportation Center Research Report
Rigid pavement thickness design systems investigated during this study were the 1986 AASHTO, American Concrete Pavement Association (ACPA), Portland Cement Association (PCA), and Kentucky methods. The ACPA system is a computer program based upon the 1966 AASHTO design equation. It was difficult to evaluate and compare the Kentucky method to the PCA system because the input and analysis procedures differ greatly.
The Kentucky method is based upon the fatigue relationship involving the value of work at the bottom of the concrete pavement caused by the applied load and repetitions of an 18-kip single axleload. The AASHTO method was derived from …
Soil-Bridge Abutment Interaction, Bobby W. Meade, David L. Allen
Soil-Bridge Abutment Interaction, Bobby W. Meade, David L. Allen
Kentucky Transportation Center Research Report
Presented herein are analyses of 6 bridge approaches. Lateral movement and settlement of the foundations and embankments are discussed. Result·s of slope stability and finite element analyses are related to measured movements. A graph for predicting approach pavement settlement is included. A theoretical approach model was used to run an extensive series of finite element analyses. Movements resulting from these analyses are presented with several variable model conditions. Variable conditions include embankment and foundation configuration, soil cohesion, and soil friction angle.
