Abstract: The invention relates to a road surface marking tape intended for temporary use and being of the kind that includes a base layer of non-cured or non-vulcanized soft elastomeric material, and reinforcing material embedded in the base layer. The reinforcing material is comprised of short fibers of non-metallic material distributed generally uniformly in the base layer in an amount corresponding to 5-50%, preferably 10-20% of the weight of the base layer. The reinforcing material is preferably comprised of fibers of fabric, plastic or carbon with lengths generally between 0.5 and 5 mm, preferably between 1 and 3 mm. The elastomeric material is usually a rubber of the acrylnitrile-butadiene type.
