Thermoplastic Traffic Stripe Maintenance Program

摘要

During the 12-month period of the project, a computerized inventory of all thermoplastic traffic stripes in the state was established. The inventory allows easy access to information pertaining to thermoplastic striping and enables short term scheduling and long-range planning of striping operations. The thermoplastic evaluation procedure was modified to include objective measurements in addition to subjective ratings. A retroreflectometer and a digital thickness device were used for the objective measurements. Loss of retroreflectivity and thickness can now be monitored over time.
