Two laboratory tests were used to evaluate several physical properties of traffic stripe paints. The objective of this evaluation was to provide a better understanding of these properties as they relate to predicting durability of paint stripes in the field. Tensile tests of free film specimens of paint yielded several properties derived from the stress-strain curves. Abrasion tests provided results for paint specimens tested both dry and submerged in distilled water. The tests produced consistent and repeatable results. Ten paint samples representing several different volatile and nonvolatile vehicles were evaluated using the two laboratory tests. The paints were different as reflected in the tensile properties. The water-based paints were considerably more ductile than the organic solvent-based paints. The load rate used for the test had significant effect on the results because of increased viscous creep introduced at slower load rates. The 10 paints were evaluated in the field for 5 years. Three water-based paints exhibited superior performance. The performance of these water-based paints correlated well with modulus of toughness computed from tensile tests and wear indices from dry Taber abrasion tests.
