Standard Round Tube (.25 ID x .60 OD)
Each tube should be secured at each end of the roadway by using a galva-
nized C-Clamp, Chinese Finger, Figure 8 Grip or an End Plate. Whichever is
used, ensure the proper nail size is used. Use the longer nail size (2.5 inch or
longer) in hotter temperatures to compensate for softer road surfaces. In cold
weather applications, the asphalt becomes harder, making it more difficult
to drive in the nails. In this situation, smaller nails (1.5 inch) can be used.
Next, secure the tube on the traveled portion of the road surface by using
mastic. As a minimum, one piece of mastic should be placed on the zone
line (middle of the road) and two pieces of mastic should be placed in each
lane. Additional mastic should be used as deemed necessary to prevent the
tube from moving when stuck by a vehicle. Refer to the diagram below
for more details.
Mini-Road Tube (.20 ID x .375 OD)
Since mini tube is smaller and lighter than standard round tube, less hard-
ware is required to install the tubes.
Webbing can be used to secure the tube at each end of the roadway. You
may tie a knot at the far end of the tube instead of using an end plug or PK
nail. Since the mini tube is light and low profile, you may use duct tape or
two-inch mastic to secure the tube to the roadway. Generally, three pieces
