Pavement markings are installed and maintained by the Sign Shop. These markings include crosswalks, center lines, lane lines, pavement messages, arrows and stop bars. The markings are installed with the use of paint and thermoplastic. The paint is applied with the use of a truck mounted paint striper. The thermoplastic is applied with a small hand liner that holds 250 pounds of material. We also have a thermoplastic application trailer with two 800-pound kettles that we use for large thermoplastic jobs. Before thermoplastic can be applied it has to be heated to around 400 degrees Fahrenheit.
The Sign Shop also uses preformed thermoplastic for turn lane applications. This is installed with the use of a heating torch that melts the thermoplastic and allows it to bond to the road.
