The pipe appears to be performing well. The …

Experimental Analysis And Analytical Modeling Of Bridges With And Without Diaphragms, James J. Griffin, Issam E. Harik, David L. Allen

Kentucky Transportation Center Research Report

Two prestressed concrete (P/C) I-girder bridges along the coal haul route system of Southeastern Kentucky were constructed with a 50 degree skew angle. One of the bridges has concrete intermediate diaphragms, while the other bridge has no intermediate diaphragms. Bridges of similar design along coal haul routes have experienced unusual concrete spalling at the interface of the diaphragms and the bottom flange of the girders. The purpose of this report is to identify the cause of the damage, and to evaluate the effectiveness of intermediate diaphragms.

Experimental static and dynamic field testing was conducted on both bridges. All field tests …

A Methodology For Evaluating Large Truck Access To Intermodal And Other Facilities, Lisa Aultman-Hall, Michael Hill, Kenneth R. Agent

Kentucky Transportation Center Research Report

In a recent project for the Kentucky Transportation Cabinet (KYTC), researchers were tasked with developing a method to objectively evaluate the access for large trucks between intermodal or other truck traffic generating sites and the National Highway System (NHS). The routes evaluated were the actual roadway segments used by large volumes of trucks traveling between the intermodal or other facilities and the NHS. This choice to evaluate specific heavily used roadway segments, as opposed to evaluating an entire highway or roadway corridor was based on the recommendation of the state-wide Intermodal Advisory Panel which advised the Cabinet on intermodal issues. …

Seismic Isolation Of A Highly Skewed, Prestressed Concrete Girder Bridge, Bradley Neil Robson, Issam E. Harik, David L. Allen

Kentucky Transportation Center Research Report

A relatively new approach for designing or retrofitting highway bridges in seismic zones involves isolating the superstructure from the substructure. Through experimental and analytical investigations, this study evaluates the effectiveness of isolating one particular bridge: a highly skewed, prestressed concrete, slab-on-girder bridge. Dynamic testing of the bridge was performed using the pullback, quick-release method. A three dimensional finite element model of the bridge was created. It was refined, or calibrated, to match experimentally determined natural frequencies and mode shapes. Time-history analyzes, using site-specific acceleration records, were conducted for the seismically isolated bridge model and an identical, non-isolated bridge model.

Evaluation Of Corrugated Steel Pipe Culverts On Ky 61, Cumberland County, L. John Fleckenstein, David L. Allen, Brad W. Rister

Kentucky Transportation Center Research Report

In February of 1998, the Kentucky Transportation Cabinet requested that the Kentucky Transportation Center investigate three corrugated metal pipe culverts on the relocation project of KY 61. The pipes were installed in June and July of 1997. The embankments over the three pipes were completed In October of 1997. Based on the information that was gathered, it appears that the pipes were manufactured according to specifications. The gage of the pipe is on the lower end of acceptance. The pipes appear to have been well aligned and properly bedded. Some of the dents and buckles in the pipe may have …

Embankment Construction Using Shale, Tommy C. Hopkins, Tony L. Beckham

Kentucky Transportation Center Research Report

Shales have been used extensively in the construction of highway embankments, and other earthen structures, because of the vast amounts of these materials located in many areas of the country and the lack of economical and alternate available materials. Because shales exhibit a wide range of engineering properties and behaviors, many problems have occurred. Numerous shale embankment failures have occurred generally some 1 to 10 years after construction. Settlements of 1 to 3 feet (0.3 - 0.9 m) have been observed in many old embankments and required numerous asphaltic overlays. Shale embankments that settle continuously have been observed to fail …

Roadway Incident Emergency Response: Workshop Summary And Detour Maps, Jerry G. Pigman, Kenneth R. Agent, David H. Cain

Kentucky Transportation Center Research Report

Delays associated with incidents and accidents on heavily traveled highways have been recognized as a major inconvenience and a burden on the driving public. Heavy traffic volumes on interstates in Kentucky result in significantly increased probability for delay occurrences. When there is an occurrence which disrupts traffic, the adverse effects are widespread. High volumes of trucks use the north-south corridors in the state and delays can produce significant costs to both shippers and users of products being shipped.

Many efforts are underway to address the problems associated with congestion; including improved traffic management techniques and applications of advanced technology. A …
