All measurements should be made in the direction of traffic flow, except on the centerline of two-lane roads where the required number of measurements should be made in each direction. Both single and double lines are to be measured, and the acceptance criteria should be applied for each line in both directions. Inspectors should realize that the Mirolux 30 machine normally shoots a beam of light approximately 6 to 12 inches. in front of the machine's lens. Therefore, the lens should be located approximately 6 to 12 in. from the flat area of rumble stripes. When the light falls in the bottom of the rumble, the retroreflectivity readings are usually lower than the backside or top of the rumble area because of the change of light beam angle, and for that reason, care should be taken to avoid taking readings in the bottom of the rumble.
