AIRFIELD MARKING PAINTS. IV: EFFECT OF FLEXIBILITY ON SLURRY-SEALED ASPHALT

A FIELD EXPOSURE STUDY WAS CONDUCTED ON EXPERIMENTAL AIRFIELD MARKING PAINTS WITH RELATIVELY HIGH FLEXIBILITIES. WHILE FLEXIBILITY MUST BE GREATER THAN THE MINIMUM REQUIRED IN FEDERAL SPECIFICATION TT-P-85B FOR GOOD PAINT PERFORMANCE, A FURTHER INCREASE IN FLEXIBILITY DOES NOT NECESSARILY RESULT IN BETTER PERFORMANCE. A STATISTICAL ANALYSIS OF THE TEST VARIABLES REVEALED THAT OLEORESINOUS PHENOLIC VARNISH GENERALLY PERFORMED BETTER THAN ALKYD PAINT STRIPES, THAT LIFTING WAS GREATER FOR DOUBLE-THICKNESS STRIPES THAN FOR SINGLE-THICKNESS STRIPES, AND THAT CRACKING WAS FASTER FOR LONG OIL THAN MEDIUM OIL ALKYD PAINTS AND FOR MEDIUM OIL THAN FOR LONG OIL OLEORESINOUS PAINTS. MEDIUM OIL PAINTS HAD LESS OVERALL CRACKING THAN LONG OIL PAINTS. THERE WAS GENERALLY LESS CRACKING AND LIFTING WITH PAINTS CONTAINING NO PLASTICIZER. TRICRESYL PHOSPHATE FORMULATIONS GENERALLY HAD LESS EDGE CRACKING AND LIFTING THAN COMPARABLE FORMULATIONS WITH DIBUTYL PHTHALATE AS A PLASTICIZER. THERE WAS A HIGH CORRELATION BETWEEN EDGE CRACKING AND THE LIFTING OF SLURRY SEAL. /AUTHOR/
