Lines are prone to loss of gloss and wear over time due to obsolescence, traffic impact and periodic or preventive maintenance activities, and sometimes require regular maintenance. These lines include separation lines, road edge lines and pedestrian crossing lines. If these lines are not valid, they are removed and replaced with new lines or re-painted without removing them. The road surface must first be cleaned by removing the scattered material. The correct equipment is used to remove the old lines by peeling. The roads are then planned using a special cargo vehicle for planning, equipped with storage tanks for paint, storage tanks for solvents, an air pump, spray head and sand spray machine. When it is necessary to re-paint intermittent lines, the newly dyed lines should be as close as possible to the original lines, and the road paint should be re-painted when the paint is darkened or when it loses its reversibility to light Temporary lines are placed on the shoulder if it is decided to re-pave the road. The temporary line shall be placed using the planning apparatus equipped with a distillation arm. The old line shall be used as a guide to the laying of temporary lines on the shoulder. A small amount of paint shall flow from the distillation arm after placing The new surface and the charting machine follow the temporary lines as a guide to place the lines on the new surface directly above the old line.Reflective reflective lines consisting of a ready mix of adhesive, yellow or white pigment, a specially packed filler filler and reflective glass granules shall be used for use and pasted on the finished finished area. Additional reflective glass granules shall be added before the paint membrane dries or Solidifies and takes its final position, using the drop-on method or pressurized method. The white and yellow reflective lines must conform to the specifications of AASHTO M 249 . The surface glass pellets / granules must conform to( AASHTO M 247, Type I ). Thermoplastic can be used to plan the roads requiring paint more than twice a year. The thermoplastic inverter is mixed with the glass granules and the road is planned as a fluid. Specific reflector thickness and width and resistance to deformation after cool, and thermoplastic is better than paint when used on wet surfaces, because it protrudes above any water surface.The average life of the planning materials varies with the traffic volume. After long service, the thermoplastic retains its reflective properties. The thermoplastic materials used in road planning are shown as white or yellow blocks weighing about 22.7 kg and approximately 0.3 m at 0.9 m at 0.05 m. The surface of the road should be washed with a cleaning solution and rubbed with a jagged upright broom, and then rinsed with clean water to remove any clay material or build up of oils.The thermoplastic material shall be placed on the surface with a propulsion machine or spraying machine at a temperature between 205 and 218 ° C. The sprayed material shall be of a thickness of 3.2 mm to 4.8 mm. During spraying of thermoplastic, glass granules shall be sprayed by 1 kg Every 10 m 2 of the surface, when the thermoplastic material is sprayed in the fish and the temperature previously indicated, the thermoplastic materials are ready to withstand traffic within two minutes when the air temperature is 10 ° C and 10 minutes when the air temperature is 32 ° C.
