A solid white line indicates the outer edge of a roadway, and it may be crossed only by traffic moving to or from the shoulder.. Small flaws caused by differential strains may be combined into longitudinal cracks along the markings. In England, the idea of painting a center white line was first experimented with in 1921 in Sutton Coldfield, Birmingham. Look out for them when approaching junctions or a central refuge. Solid white lines are also used to mark the outer edges of a road. Retroreflective glass beads are applied using a separate bead gun behind the epoxy spray gun. A) HOV lane. Sand blasting methods utilizes high-pressure air and a nozzle to blast sand aggregate. The line was put down as an experiment as there were a lot of accidents there, even in the early days of the motor car. no turnings, sharp bends ahead etc. Most European countries reserve white for routine lane markings of any kind.
