Pavement markings are designed to provide important information and communication to motorists and pedestrians as they use the road system. The markings are usually done following specific standards and regulations set and enforced by local, state, and federal governments. The regulations are meant to ensure uniformity on all roads so that the information that is communicated by the markings is standard. When in need of Line striping Maryland should be visited.
There is a wide range of materials that are used to mark roads today. The choice of material is supposed to be done in a way that achieves certain goals. Some of the goals that need to be achieved are appropriate service life, cost effectiveness, and compatibility with the site. The Department of Transportation is the government body in the US that is charged with ensuring safety on all road systems in the US.
There are great differences in the cost and service life of various materials used to mark roads. The effectiveness of the materials on different surfaces also varies. However, how the material will perform on the pavement depends on the type of roadway surface, volume of traffic, and environmental conditions in the area. Pavement markings in different places are affected differently by these factors.
When considering weather, abrasion caused by snow removal activities is responsible for the most damage to pavement. Snow plowing equipment routinely cause friction and leave markings damaged, especially in places where snow happens heavily. This is shown by rapid deterioration of markings in places where snow is removed more frequently.
To counter the effect of snowplows on markings, recess pavement markings are used. Recess pavement marking involves installing the marking material into grooves. This ensures that the material is not accessible to snow removal equipment. The effect is that the markings stay longer, but the cost of recess pavement marking is usually higher than standard marking.
How long the markings will stay on the pavement can also be determined by the type of surface to be painted. The bonding characteristic of marking materials is highly affected by surfaces made of Portland cement concrete and hot mix asphalt. This proves that the surface can affect how the material bonds and thus affecting how long it can last. How long the markings will last is also influenced greatly by the volume of traffic experienced by the area. Deterioration rate is directly proportional to the amount of traffic.
The Department of Transportation has approved several materials to be used to mark pavements. Some of the most commonly used materials are epoxy, polyuria, water-based paint, preformed plastic, thermoplastic, and modified urethane among others. These materials also exist in more than one formulation in some cases. Every formulation must however be approved for use by the DOT. Some of these materials are also compatible with each other while others are not.
In case of re-striping, it is important for the material used to be compatible with the already existing one. If not, then the existing materials must be scrapped completely before re-striping is done. To achieve expected service life, certain conditions must exist during the installation process. There are several factors that must be observed. The major ones are material application rate, wind velocity, pavement surface condition, pavement surface moisture, material temperature, ambient temperature, and pavement temperature among others.
