Thermoplastic Thickness Measuring Device
Topics that will be covered
Step 1. Zero-out Gauges
Step 2. Remove base-plate
1. Florida Method of Test
FIELD EVALUATION of
Standard Specifications Section 711
Developmental Specs. Sections 701 & 702
Measuring Flat Line
Center the gauge over the marking material in an area avoiding glass spheres and read the values of all three dial indicators.
By procedure, the staff will take three measurements with them being at the beginning, middle and end of each one mile section of line type. Then average of the three location measurements shall be used for acceptance of the one mile section of line type (FM 5-541).
Measuring Audible Cookies
Cookies are too tall for device to measure.
Take a reading across the cookie in the same direction as the line
Then one right in front of or behind the cookie, add the two numbers together.
Transverse Bars w/ Inverted Rib
Device can be used to measure this type of line.
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.
Thermo on FC-5
Having trouble getting required thickness due to the road soaking up material.
Pay close attention to final thickness measurement.
