this Guideline is inspired by the need to frame in a single document the Italian and European technical standards, which cover the performance of road markings, currently in force, which are contained in or may be included, together with the requirements related to mandatory standards, in particular specifications, procurement of public works which constitute the discipline of detail and technique. The document is developed in order to provide to anyone who works in road marking works a simple tool containing the right technical information to learn about the products on the market, understand how these are built up and which performances can give.
