History of Pavement Marking

Although it is true that some ancient roads had white bricks to mark their centers, archaeologists are uncertain whether the primary purpose was traffic control or decoration. In ancient times, if it was necessary to separate lanes of travel, medians were used more often than any other method. Once automobiles became more numerous, however, pavement markings became an important safety feature.

History of Pavement Marking – Two Types

During the 1910s, many states began painting lines down the centers of highways and streets to separate traffic flowing in opposite directions. California, Michigan and Oregon were the first states to embrace painted pavement markings to denote the center of the roadway. Painted lane dividers and edge markers followed within the decade. Paint remains the most common material used for pavement markings.

Used alone or with painted lines, reflective markers are increasing in popularity on highways and freeways. These markers may be affixed to the top of the pavement or recessed into the pavement. Because reflective markers tend to generate vibrations or tire noise, they are sometimes used to warn drivers that their vehicles have strayed across a lane marker.

Types of Paint Used for Pavement Markings

Many states and municipalities have banned the use of pavement paints containing solvents. Therefore, most pavement paint used today is either water-based or thermoplastic.

• Water-based paints are not as durable as thermoplastic. Depending on traffic and climate, they will last between two years, in some cases three or four years. They are suitable for areas that receive low volumes of traffic or for markings that are intended to be temporary.
• Thermoplastic markings can last longer than water-based paint; their expected life under normal usage is between three and six years. Thermoplastic markings are heated to approximately 400 degrees Fahrenheit before they are applied, so contractors must have different equipment than is used for water-based paints.

Water-based paints and thermoplastic markings can have reflective beads embedded in their surfaces. However, additional reflective beads are contained in the thermoplastic mix; as the surface wears off, these additional beads are exposed to help retain the markings’ reflective properties.
