Mode ofReflectanceClass Q Description

R1 0.10

Portland cement concrete roadwaysurface. Asphalt road surface with aminimum of 15 percent aggregatescomposed of artificial brightener (e.g.,Synopal) aggregates (e.g.,abradprote. quartzite)

Mostly

diffuse

R2 0.07

Asphalt road surface with anaggregate composed of a minimum 60percent gravel (size greater than 10millimeters.)

Mixed

(diffuse and

specular)

Asphalt road surface with 10 to 15percent artificial brightener inaggregate mix (Not normally used inNorth America.)

R3 0.07

Asphalt road surface (regular and car-pet seal) with dark aggregates (e.g.,trap rock, blast furnace slag); roughtexture after some months use (typicalhighways.)

Slightly
