Feeding back to feed forward

Lucy Wheatley, Alex McInch, Scott Fleming & Rhiannon Lord
Students construct meaning through relevant learning activities (Biggs, 2003) which are largely determined by the type, amount, and timing of feedback (Carless, 2006). The aim of the present study was to develop a greater awareness and understanding of formative assessment and feedback practices and their relationship with learning. During 2011 five focus group discussions were undertaken with students and academic staff involved with a range of modules and degree pathways at a UK University. Three...

2000 Safety Belt Usage Survey in Kentucky

Kenneth R. Agent
The objective of this study was to establish 2000 safety belt and child safety seat usage rates in Kentucky. The 2000 survey continues to document the results after enactment of a statewide mandatory safety belt law in 1994. Data were collected at 200 randomly selected sites spread across Kentucky. Data from the individual sites were combined into a statewide percentage considering function classification, geographic region, and vehicle miles traveled. The data show that the usage...

Two separate paid media campaigns and enforcement periods were conducted. One dealt specifically with pickups while the other was a...

Detailed Seismic Evaluation of Bridges along I-24 in Western Kentucky

Ching Chiaw Choo, Issam E. Harik & Peng Yuan
This report presents a seismic rating system and a detailed evaluation procedure for selected highway bridges on/over I-24 in Western Kentucky near the New Madrid Seismic Zone (NMSZ). The rating system, based upon structural vulnerability, seismic and geotechnical hazards, and socioeconomic factors, was used to rank 127 (82 on and 45 over I-24) bridges on/over I-24. A total of 14 bridges were selected and subsequently evaluated using a capacity/demand ratio method outlined in the Seismic...

Value of Research from 2000-2005

Donald L. Hartman
The abstracts of the 79 SPR reports completed by KTC researches for 2000-2005 were compiled. Seven projects were selected for value review to demonstrate the various types of benefits that accrue from SPR project research. This review compared objectives with results and described the nature of the benefits (some quantifiable). All of the projects were analyzed to determine: 1) the Kentucky Transportation Cabinet (and FHWA) goals supported and 2) the types of benefits that would...

Spatial Database For Intersections

Eric R. Green, Christopher L. Blackden & Michael A. Fields
Deciding which intersections in the state of Kentucky warrant safety improvements requires a comprehensive inventory with information on every intersection in the public roadway network. The Kentucky Transportation Cabinet (KYTC) had previously catalogued only those intersections where state-maintained roadways met. However, this inventory did not account for intersections between state- and locally-maintained routes, nor was it designed to accommodate regular updates. As such, the Kentucky Transportation Center (KTC) at the University of Kentucky developed a...

Pavement Settlement Issues and Hydro-Geochemical Water Testing Results for the Cumberland Gap Tunnel

Brad Rister, Clark Graves & Jim Dinger
Both Ground Penetrating Radar (GPR) surveys and Hydro-Geochemical Water Testing (HGWT) have been performed at the Cumberland Gap Tunnel to determine why the reinforced concrete pavement has settled in various areas throughout both tunnels. To date, approximately 7,300 total square feet of pavement surface has voids beneath it that range from 0.05 to 40 inches in depth. Both GPR and HGWT results indicate that approximately 0.75 to 1.5 cubic yards of limestone sub-base material leaves...

Comparison of Three Methods of Pavement Design for Lexington-Fayette County

David L. Allen
It is imperative in an era of limited budgets for construction and maintenance of streets and highways that a rational approach be followed for managing these funds. One of the first steps of this management process is the adequate and proper design of new streets and roads. In the interest of having a more rational system of design, representatives of the Lexington-Fayette Urban County Government requested the Kentucky Transportation Center to assist in the development...

Allocation of Highway Costs and Revenues

Jerry G. Pigman & John A. Deacon
This highway cost and revenue allocation study is the fourth of a recent Kentucky series begun in 1982. Experience gained with each study has resulted in subsequent refinements that have enlarged the data base, enhanced the accuracy, and simplified the study process. One of the long-term aims is to develop an easy-to-use process for continuously monitoring effects of changes in traffic patterns, in finance and tax policy, and in highway expenditures. The primary objective of...

Earthquake Hazard Mitigation of Transportation Facilites for Graves County

L. John Fleckenstein, David L. Allen & Vincent P. Drnevich
Concern has grown in recent years over the seismic activity of the New Madrid seismic zone in Western Kentucky. Graves County, Kentucky is located in this region. To permit emergency medical, supply, and equipment traffic into this area after an earthquake has occurred, the Kentucky Transportation Cabinet is interested in the possibility of keeping selected routes passable. This report lists the routes that have been investigated and recommended as being the routes in Graves County...

Experimental Road Base Construction Utilizing Atmospheric Fluidized Bed Combustion Residue

David Q. Hunsucker & R. Clark Graves
This report summarizes findings of laboratory and field trial evaluations of two experimental test sections constructed adjacent to one another. One experimental section contained a mixture of pulverized fuel ash, residue from an atmospheric fluidized bed combustion process, and limestone aggregate. The second section contained a similar mixture but included a small amount of Type Ill cement. Both experimental sections were constructed to a total nominal thickness of nine inches. The typical design section included...

Evaluation of Highway Geometries Related to Large Trucks

Kenneth R. Agent & Jerry G. Pigman
One objective of this study was to determine the extent of highway safety and geometric problems associated with larger trucks using Kentucky's highways. The accident analysis involved both a general analysis of all truck accidents statewide as well as the identification of specific high-accident locations. A second objective was to identify criteria which can be used in identifying roadway sections that cannot safely accommodate large trucks. The accident analysis given can be used to investigate...

Correlation of Rock Quality Designation and Rock Scour Around Bridge Piers and Abutments Founded on Rock

Tommy C. Hopkins & Tony L. Beckham
Local scour around the base of a bridge pier or abutment occurs as the result of flow acceleration around the obstruction, formation of a vertical pressure gradient along the upstream end, and generation of vortices at the base of the structure. The flow patterns around piers and abutments are complex in detail, and the complexity increases as a scour hole forms in the bed around the structures. The potential for local scour at a bridge...
