The Composition and Construction Steps of Road Markings

Glass is wind proof and transparent, with stable performance. Different types of glass have different characteristics due to different use occasions, so it has a wide range of applications. When we select glass, we should not only pay attention to the price, but also have a certain understanding of its type and performance, so as to find more suitable materials. This article helps you to understand the composition and construction technology of road marking.

1. Road traffic marking lines should add glass beads for road marking

Road traffic markings are mainly set on the road surface, which are exposed to the sun, rain, wind, snow and ice, and the impact and abrasion of vehicles, so there are strict requirements for their performance. First of all, it requires short drying time and simple operation to reduce traffic interference; Second, it requires strong reflection ability, bright color to make good visibility in the daytime and night; Third, it should have skid resistance and wear resistance to ensure driving safety and service life.

In order to improve the identification of the marking at night, the brightness and durability of the marking, glass beads for road marking are added. It is a colorless and transparent ball, which has the functions of refraction, focusing and directional reflection for light. Glass beads for road marking mixed with the paint or spread on the surface of the film, the car light can be reflected back to the driver's eyes, thus greatly improving the visibility of the marking line.

2. What are the construction steps of road markings

  • Measurement lofting: setting out and making symbols according to the planning drawings and choose clear marking paint for symbols. The diameter of the symbol is approximately ten millimeters. After finishing symbol, the starting position of dotted line and obstruction line shall be marked on the road. Apply for inspection and ask for approval after inspection. And then begin marking construction.

  • Pavement finishing: manual cleaning is used to clean the road surface. Water washing and forest fire extinguishers are used to clean the road surface as needed. It is necessary to clean the road surface before marking to ensure there is no dust and other debris.

  • Marking line delimits: select mechanical spray paint, add glass beads to the paint. The content of glass beads is 0.8kg/L, before participating in mechanical mixing evenly. Test spray and adjust the application quantity according to the application quantity of standard rules until standard requirements are satisfied. Before formal construction, operators training and conduct trial work to ensure beautiful alignment. Select manual marking in special cases, and two coatings should be applied. Paint the second layer after the first layer is dry.

  • Finishing: during the construction process, the construction should be finished at the same time with no throwing, sprinkling, dripping, leakage, pollutants, and no leakage appearance of mechanical equipment. Finish a section of marking and a section of pavement, adhere to road cleaning, no pollution, and damage.

  • Safety protection and product protection: Select protective personnel when marking (standard-bearer) combined with road cone to protect safety. Select road cone to protect it after the completion of marking, rolling by vehicles is not allowed until the paint is dry.
