Pavement markings are created to provide crucial information to pedestrians and motorists when they are using roads. Markings are normally made in accordance to specific standards and rules made and enforced by the federal, state, and local governments. The rules are created to make sure there is uniformity on every road so that the information communicated by the markings is standard across all roads. When in search of companies that do line striping Maryland should be given priority.
Currently, a wide range of materials are used in marking roads. The type of material used depends on the goals intended to be achieved. The goals to be achieved by the materials include compatibility with the site, cost effectiveness, and appropriate service life. In the US, the Department of Transportation is mandated with the responsibility of ensuring there is safety on all road systems.
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.
In terms of weather conditions, the abrasion that results from snow removal activities is the main cause of deterioration of pavement markings in some places. Snow plowing equipment usually causes friction with markings on the road in places where snow is prevalent. This is indicated by faster deterioration of markings in areas where snow is removed frequently.
However, the effect of snow plows can be handled by using recess pavement markings. With recess markings, the marking materials are installed in grooves, meaning that they cannot be accessed by snow removal machines. Even though the marking stays longer with recess marking, the cost of installing them is usually more as compared to normal marking.
The kind of surface where the marking material is applied may affect its durability too. For example, surfaces like Portland cement concrete and hot mix asphalt are known for their effect on the bonding characteristic of marking materials. This implies that the bonding characteristic is normally altered by the surface, which eventually determines durability. The quantity of traffic a place experiences normally impacts the durability of markings greatly too. The more the traffic, the faster the deterioration.
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.
