Evaluation Of Wick Drain Stabilization Of Approach Fill Foundation (Bullitt County), Bobby W. Meade, David L. Allen Mar 1990

Evaluation Of Wick Drain Stabilization Of Approach Fill Foundation (Bullitt County), Bobby W. Meade, David L. Allen

Kentucky Transportation Center Research Report

The purpose of this study was to document construction procedures and evaluate the effectiveness of prefabricated wick drains for dewatering and stabilizing an approach fill foundation. Construction was observed and photologged. Foundation pore pressure was monitored with pneumatic piezometers. Settlement of the entire structure was monitored by use of control points on the retaining wall and pavement.

Construction procedures were acceptable. Wick drains have functioned as expected and the approach fill has been stable for approximately four years since construction.


Investigation Of Premature Cracking On The National Turnpike, Jefferson County, L. John Fleckenstein, R. Clark Graves, David L. Allen Mar 1990

Investigation Of Premature Cracking On The National Turnpike, Jefferson County, L. John Fleckenstein, R. Clark Graves, David L. Allen

Kentucky Transportation Center Research Report

This report discusses the investigation of the premature cracking that occurred on the National Turn pike, Jefferson County (1989). A detailed distress survey was performed evaluating each slab throughout the project site. Falling Weight Deflectometer testing was performed on every third slab. In addition subgrade samples were taken, along with the installation of three water monitoring wells. Laboratory test were conducted on the subgrade samples.

Damage that occurred near the curb inlets and manholes is probably due to insufficient compaction. The remaining damage is most likely related to the combined effects of a very soft subgrade, high water tables, and …
