Driving is so much a part of most people's lives they don't even think about how they make some crucial decisions when they are on the road. There are good reasons you don't pass on hills, turn left, or drive in the emergency lane. Drivers aren't always conscious of how much direction traffic markings are giving them constantly. A lot goes into deciding where, how, and what materials make up all the pavement marking AR drivers see everyday.
There are pros and cons to all the materials used to make the roads safer. Whether officials decide to use tapes, raised markers, thermoplastic, paint, or reflective beads is based on a wide range of factors. These factors include the daily traffic count, the function, the location, kind of pavement, availability of labor, equipment needed, life span versus cost, and how much money they have allocated in the annual budget.
Paint was the first material ever used to mark the roadways for drivers. Today paint is still the most popular and widely used material. Of the four base materials used in its manufacture, three are solvent borne, and one is water borne. The solvent borne are the most common, but because it is more environmentally friendly, the water borne paint is being applied more often than in the past.
Thermoplastic has been used since before the Second World War and is preferred by many because they do not contain solvents, which makes them more environmentally friendly. They also have the advantage of being more visible under rainy night conditions and have a longer life span than paint in warm climates. Thermoplastics are not as long lasting in cold climates however. They do require surface preparation, in the form of primer or some other treatment, in order to maximize the adhesion.
Neither one of these materials in naturally reflective. On sunny days that doesn't matter, but during nighttime hours and in wet conditions, it can be difficult to drive without some type of reflective roadway markings. Glass beads are the most common material used currently to create reflective paint and thermoplastic. Their transparency and shape help to make them naturally reflective.
Tape is being increasingly used on a permanent basis. It has a higher initial cost, and in the past was mostly used on a temporary basis to direct traffic in areas of road construction and repair. Tapes come in rolls from the factory and are applied directly to the roadway with or without the addition of an adhesive. Tape lasts as long as other materials and is easy to repair if it gets loose or torn.
A lot of drivers complain about raised markers, but that may be because they are so effective. Most people have hit these markers while going too fast and experienced the jolt and noise that accompanies that mistake. Raised markers are especially effective during rain events because they are raised above the normal waterline and can be clearly seen.
Safety is the primary concern when officials make decisions about roadway markings. They want them to be easy to recognize and clearly visible. It is up to drivers to obey their instructions.
