Retro-reflectivity Testing

Light originating from the headlights of a vehicle is reflected off pavement markings and back toward the driver. Retro-reflectivity testing methods are a means for measuring the amount of light that is reflected back.

Retro-reflectivity testing allows a DOT to determine that the markings placed comply with established minimum standards and that they will perform this important function as intended.

  • ASTM E1710 Testing Method For Dry Conditions
