Abstract : A study was made to determine the basic causes of lifting of slurry seal from asphaltic subgrade under stripes of reflectorized airfield marking paint. Lifting was greater for double-thickness than for single-thickness stripes, especially for those with paint formulations containing chlorinated rubber. Paints with lower boiling solvents caused less lifting than those with higher boiling solvents. Oleoresinous paints generally caused more lifting than alkyd paints. Oleoresinous formulations with highly aromatic solvents caused less lifting than those with solvents of lower aromaticity. Alkyd formulations with highly aromatic solvents caused more lifting than those with solvents of lower aromaticity, but the amount of aromaticity-associated lifting was less than with oleoresinous paints. The addition of a small amount of carbon black reduced lifting with oleoresinous paints but had little effect with alkyd paints. There was somewhat greater lifting with 12-inch than 4-inch-wide stripes. Numerous interactions that significantly affected the extent of lifting occurred between the paint variables investigated.
