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.
Several materials are used in marking roads today. The material is picked based on the goal that needs to be achieved. Among the goals that must be attained include cost effectiveness, compatibility, and appropriate service life. The Transport Department is the overall governing body in the US. It is responsible for making sure there is safety on all kinds of roads in the country.
The various materials that can be used to mark roads vary a lot in their service life and cost. Also, some materials are more appropriate for certain surfaces than others. The performance of pavement marking materials is usually dependent on various factors, including traffic volume, roadway surface type, and environmental conditions. These factors cause different levels of effect on markings in different places.
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.
It is crucial for the material to be compatible with the one that already exists in re-striping. Otherwise, the existent materials have to be completely scrapped off before re-striping. To obtain the expected service life, specific conditions have to be met when doing the installation process. Some factors have to be considered. The main ones are wind velocity, material application rate, pavement surface moisture, pavement surface condition, ambient temperature, material temperature, pavement temperature and so on.
