Maintenance Coatings has the equipment and experience to install all types of permanent Pavement Markings both non-durable (lasting 1 year or less) and durable (lasting 3 years or more). In selecting which type of material to use, an owner /agency must consider a number of factors such as: pavement type and condition, the desired frequency of restriping, the level of desired reflectivity. These factors must be weighed against the cost of providing the longest lasting, most highly reflective marking that can be seen day or night and sunny or raining.
Thermoplastic – a moderately priced and durable pavement marking. Thermoplastic is a granular material that becomes liquid when melted down at 400+ degrees. Once applied, thermoplastic hardens as it cools. It used on asphalt pavement and cannot be used on concrete pavement. Thermoplastic must be applied when temperatures are at least 50 degrees.
- The inlay method is a process where the permanent tape is applied to new asphalt while it is still hot in advance of the finisher roller. The roller presses the material into the asphalt, depressing it slightly to help protect it from snow plow damage.
- The Overlay method is a process where the tape is applied to existing pavement (asphalt or concrete) and tamped with a rolling device to ensure its bond to the surface. In some cases a liquid primer is applied to the pavement to strengthen the bond. While the material is very durable it is susceptible to snow plow damage unless it is recessed into the pavement.
- The Recessed method is where the material is applied to the bottom of a recessed groove for protection from plows and additional durability.
Preformed Thermoplastic (Hot Tape) – a hybrid between thermoplastic and preformed tape. It is a thermoplastic that is supplied in strips of different sizes or in symbols and letters. The material is applied to the pavement and then fused to the surface through the use of propane torches. Hot tape is the most expensive durable material, but can be manufactured in various colors and shapes to produce very specialized markings, such as bike symbols.

Recessed Pavement Marking – Recessing is a process where a groove is cut into the pavement surface and a durable marking is placed within it. The groove is cut by using diamond saw blades, resulting in a groov slightly wider and slightly deeper than the thickness of the marking material being applied. This process protects the marking from snow plows. Recessing can be used in conjunction with the application of any durable marking material and maximizes the service life and reflectivity of the durable marking. Both longitudinal and special markings can be recessed.
