Slide 18
Solution: Take a reading across the cookie in the same
direction as the line

Transverse Bars w/ Inverted Rib
Slide 23
Apply base lines having a thickness of 0.079 to 0.120 inches,
exclusive of the transverse audible bars, when measured above the
pavement surface at the edge of the base line. The profiled
baseline shall have a minimum height of 0.155 inches, when measured
above the pavement surface at the edge of the inverted rib profile.
The thickness in the bottom of the profile marking shall be 0.035
to 0.050 inches. The individual profiles shall be located
transversely across the full width of the traffic stripe. Device
can be used to measure this type of line.

Things to Remember Apply markings only to dry surfaces and when
the ambient air and surface temperature is at least 50 deg and
rising for asphalt surfaces and 60 deg and rising for concrete
surfaces. (Dev. Spec. 702-4.1) Before applying traffic stripes over
portland cement concrete surface, apply a primer, sealer or surface
preparation adhesive. (Dev. Spec. 702-4.1)
