Evaluation Of Geocomposite Pavement Panel Drains Installed In A Sand Backfill Under Revised Installation Specification, L. John Fleckenstein, David L. Allen

Kentucky Transportation Center Research Report

Prior to 1989, highway edge drains were backfilled with the existing trench material and dynamically compacted with a tamping shoe. The net result was damage to the inner core of the edge drain.

In response to these problems the installation specification was revised in 1989 to insure the integrity of the drainage system. The revised method of installation consisted of moving the panel to the shoulder side of the trench and then flushing a sand slurry into the trench for backfill. Flushing the sand eliminates the need for mechanical compaction.

Since 1989, two projects have been completed using the revised …

Performance Evaluations Of Crushed Sandstone Aggregates In Bituminous Bases (Data Appendix To Report Ktc-90-26), David Q. Hunsucker, R. Clark Graves

Kentucky Transportation Center Research Report

The principal objective of the research effort was to develop historical performance data for bituminous sandstone pavements and bituminous limestone pavements relative to visual distress, pavement rutting characteristics, and structural condition using deflection measurements. Data relative to Road Rater deflections, pavement rutting, condition ratings based on subjective visual surveys and objective data such as skid resistance and rideability, were collected and analyzed during the course of the study and reported herein for the routes investigated.

It was concluded, based upon information gained during the evaluation period and presented in this report, that pavements constructed with bituminous sandstone bases do not …

Evaluation Of Flexible Delineator Posts, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

The objective of this study was to install a small number of lightweight metal u-channel posts with a round delineator and a small number of commonly used flexible posts and evaluate their performance. Three types of flexible posts were installed. They included two posts manufactured by Carsonite and one manufactured by Safe-Hit.

The results of the limited field tests does not support widespread use of flexible posts. Substantial durability problems were encountered with the flexible posts. Future use of flexible posts should be limited to potential high-hit areas such as gores at urban interchanges. While the durability of the metal …

Ground Modification Systems (Stone Columns And Wick Drains In Jefferson County), Bobby W. Meade, David L. Allen

Kentucky Transportation Center Research Report

The purpose of this study was to document construction procedures, monitor field performance, and make recommendations as to the effectiveness and future use of stone column and wick drains for ground modification purposes. This project involved the use of wick drains to accelerate consolidation in bridge approach foundations and stone columns to improve foundation support for reinforced soil walls supporting bridge abutments.

This effort was executed by use of field inspections, photologs, and instrumentation to monitor field response. Instrumentation included earth pressure meters, multipoint settlement gages, slope inclinometers, settlement platforms, and piezometers. Wick drain performance was satisfactory. One reinforced soil …

Analysis Of Traffic Accident Data In Kentucky (1985-1989), 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 1985 through 1989. 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 …

Road Rater Correlation, R. Clark Graves, David L. Allen

Kentucky Transportation Center Research Report

In this study, a correlation has been conducted between the Model 400B and the Model 2000 Road Rater. Also contained in this study, is a study of the linearity of the Road Rater measurements. Information gained from this study will provide better understanding of Road Rater measurements.

1990 Safety Belt Usage Survey And Evaluation Of Effectiveness In Kentucky, Kenneth R. Agent

Kentucky Transportation Center Research Report

The objective of the survey was to establish 1990 safety belt and child safety seat usage rates in Kentucky. Data were collected at 100 sites and combined based on vehicle miles travelled for a given type of highway, rural or urban location, and county population category. Also included in this report is an analysis of accident records evaluating the effectiveness of safety belts.

Statewide usage rates were 32 percent for drivers and front-seat passengers (over 19 years of age) and 57 percent for children under four years of age (front and rear seats). Usage rates had increased significantly in 1990 …
