A Durable Airfield Marking System.
Abstract
This report describes a 4-year work unit on the selection, development, and testing of a novel airfield marking system on ceramic-coated aluminized steel (CAS) tiles. The CAS tiles were developed to replace painted center marking lines that are obliterated by rubber streaks from jet tires from landing aircraft. The tiles are recessed or set into the pavement by grinding out 50- by 30-foot sections (1/8 inch deep) and bonding the tiles with epoxy/polyamide adhesive (2,000- to 5,000-psi tensile strength). The tiles can be easily cleaned by spraying with aqueous detergent and wiping off the rubber residue. The tiles are flexible, weather-resistant, chemically resistant, and highly reflective in day or evening, without retroreflective glass spheres. At $2.00 to $5.00 sq. ft., the CAS tiles are much more expensive than Federal Specification TT-P-1952 latex paint (about $0.10 sq. ft.), but the high initial cost can be offset in 1 year by lower maintenance costs. Although these CAS tiles are still being tested for Air Force use, the life cycle might be 5 to 10 years before replacement.
