Abstract : A study was made to determine the basic causes of deterioration of white airfield marking paints on unslurried asphalt. Deterioration was greater for double-thickness than for single-thicknesses stripes, and greater for paints with chlorinated rubber than those without chlorinated rubber. Alkyd resin paints generally performed better than oleoresinous paints. Oleoresinous formulations with highly aromatic solvents performed better than those with solvents of lower aromaticity. Alkyd formulations with solvents of low aromaticity performed better than those with more aromatic solvents. Both alkyd and oleoresinous paints performed better with solvents of lower boiling range. The addition of a small amount of carbon black was slightly beneficial overall, most notably to double-thickness stripes of alkyd paint. Stripe width was not an important factor in paint deterioration. Numerous interactions significantly affecting paint deterioration occurred between the paint variables investigated. (Author)
