Marking Products with Average to Long Service Life
The alkyd paints used for marking pavement have a service life of less than one year in certain situations. Road safety is consequently affected. New marking products, which perform better, are now available.
To evaluate the performance of new marking products which produce better results than the alkyd paint currently being used. To determine the cost/benefit ratio of the different products. To contribute to drawing up an intelligent pavement marking policy which will increase highway safety.
Set up test sites, using longitudinal and transversal lines on actual roads that are inspected in the spring and fall. Perform all the usual laboratory tests to characterise the products.

La situation de la signalisation horizontale au Québec
(Published in French only in Actualités Innovation)
Results and recommandations:
The study established, first of all, that products with two components, one of which is epoxy resin, are the most promising; second, that water-based products can be used instead of alkyd-based ones, with an equivalent result; and finally, that the prefabricated films and methyl methacrylate were far superior to all other products tested, in terms of durability. The study also afforded the opportunity to develop a functional classification of marking (durability and retroreflection).
