Sensitivity Study Of 1986 Aashto Guide For Design Of Pavement Structures, Herbert F. Southgate Nov 1991

Sensitivity Study Of 1986 Aashto Guide For Design Of Pavement Structures, Herbert F. Southgate

Kentucky Transportation Center Research Report

A sensitivity study of 14 items added to the 1986 AASHTO Guide for Design of Pavement Structures indicated: (1) variations in percent reliability were most influential on the design EAL for the same pavement structure while (2) variations in standard deviations had minimal effects. (3) Resilient moduli for base and subbase materials are very dependent upon stress state (or bulk stress). (4) A method was developed to quantify the effect of drainage capabilities for various soils and its effect upon reduction in structural coefficients for base and subbase materials. (5) Literature review revealed 13 relationships to define soil stiffness. The …


Evaluation Of Pe Film, James E. Funk, Theodore Hopwood Ii, Christopher M. Oberst Oct 1991

Evaluation Of Pe Film, James E. Funk, Theodore Hopwood Ii, Christopher M. Oberst

Kentucky Transportation Center Research Report

Laboratory tests were conducted to assess the ability of a 3-mil thick adhesive-backed polyethylene film (Polymask) to protect vehicle paint finishes from acid-rain damage. The laboratory tests employed conditions known to be relevant to actual service conditions including: 1) automotive paints of various colors, 2) simulated acid-rain solutions (of pH values from 2.2 to 5.5), and 3) service temperatures (120 to 160 °F). Laboratory tests included cyclic evaporation and soak tests similar to those employed in a previous series of tests for Toyota (1). Cyclic evaporation tests were performed for 12 cycles and the soak tests were performed for 5 …


Value Of Research, Kentucky Transportation Center Oct 1991

Value Of Research, Kentucky Transportation Center

Kentucky Transportation Center Research Report

Transportation research in Kentucky has been ongoing since 1914. The Road Materials Testing Laboratory was established that year at the University of Kentucky. Operation of the laboratory commenced in 1915 under the guidance of Professor D.V. Terrell who later became Dean of the College of Engineering. Dean Terrell often noted that the purpose of research was not to save money but to make it go farther. Public funding was never sufficient to accomplish all that various agency personnel considered essential nor that which the public deemed necessary and research was conducted most often for the purpose of gaining more for …

Analysis Of Traffic Accident Data In Kentucky (1986-1990), Kenneth R. Agent, Jerry G. Pigman Sep 1991

Analysis Of Traffic Accident Data In Kentucky (1986-1990), Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

This report includes an analysis of traffic accident data in Kentucky for the years of 1986-1990. A primary objective of this study was to determine average accident statistics for Kentucky highways. Average and critical number and rates of accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.

Another objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety Plan. County and city …


Evaluation Of Stamark Brand Bisymmetric 1.75 Grade Pavement Marking Tape, Kenneth R. Agent Sep 1991

Evaluation Of Stamark Brand Bisymmetric 1.75 Grade Pavement Marking Tape, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objective of this project was to evaluate the performance of Stamark Brand Bisymmetric 1.75 Grade pavement Marking Tape (Series 320) on a large-scale installation on Interstate 24 in McCracken County. The evaluation consisted of periodic inspection of the tape to determine its durability, appearance, and reflectivity.

The tape has demonstrated good performance after two years in service. No durability problems were noted. While the appearance of the tape was not as bright as a typical traffic paint, it was adequate. The tape has maintained a high level of reflectivity. The performance of the material would potentially warrant additional use …
