What type of paint is used for road marking and how do they make it reflective?
Road marking paint is specially formulated for the traffic. Several manufacturers produce this paint. Both the yellow and white paint are alkyd-based paint. The Ministry tests road marking paint on a regular basis to assess its suitability for road marking Often stop bars and crosswalk are marked using thermoplastic materials rather than paint. At these location thermoplastic is much more durable and lasts up to five times longer than paint. Road marking are made reflective by the application of specially manufactured glass beads which are added to the paint after it is sprayed on the pavement.
