R2/RA2 reflective refers to a specific type of reflective material used on road signs. It stands for Retroreflective Class 2/Class RA2.
Reflective materials are designed to make road signs more visible, especially at night or in low light conditions. They work by reflecting light back to its source, such as the headlights of a car. This makes the sign easier to see and read, improving overall road safety.
R2/RA2 is a classification that indicates the level of reflectivity of the material. Class 2 (R2) is typically used for permanent signs on major roads, while Class RA2 is used for temporary signs or signs on lower-speed roads.
The reflective material used in R2/RA2 signs has special properties that help it reflect light efficiently. It is made up of tiny glass beads or prisms that are embedded in a durable, weather-resistant material. When light hits the sign, it bounces off the beads or prisms and returns to the source, making the sign highly visible even from a distance.
In summary, R2/RA2 reflective refers to a high-quality reflective material used on road signs, making them easier to see and read, especially at night or in low light conditions, thus enhancing road safety.
