Abstract

Through the cooperation of the Pennsylvania Department of Highways, the titanium pigment corporation has made road tests of new traffic paints. Some of the results of these tests are presented in this paper. Road testing of traffic paints is important as there are no laboratory techniques or tests which will give quick, accurate durability evaluations of the paints. Early tests indicated that it was possible to use the calcium sulfate extended rutile titanium pigment in a traffic paint without sacrificing durability. Tests were continued with this pigment as it was one of the most economical methods of introducing hiding into the paint.

RESULTS are given showing that the alkyd-type vehicle is preferable for traffic paints of better than average durability. Formulation changes produce distinct variations in durability even in an alkyd vehicle. The road tests have shown the versatility of the alkyd type traffic paint. There are indications that this type of paint might be used as an all-purpose paint on all highways, either with or without reflectorizing beads.
