Abstract:
The ADSC/DFI Anchored Earth Retention Committee has had many discussions in recent years related to fusion bonded epoxy coatings. Remaining in question is whether or not the A934 (purple) coating has properties which offer significant performance advantages over A775 (green) coating. This has become more of an issue in recent years as growing number of designers believe A934 is superior and requirements for conformance to ASTM A934 in contract specifications are now being seen over an expanding geographical area which includes several state DOT's.
ADSC and DFI contributed funding for research on both coating products. This presentation will discuss the findings of this research.
