2. Uncoil the sensor cables and place them in the slot.
Check that the DTS12G sensor is not covered.
3. Insert the putty to the bottom of the slot.
a. Take a generous lump of hard-setting putty (approximately ⅓ of the size of DRS511)
and roll this in your hands until it becomes soft.
b. Shape the piece into a cone and place it at the bottom of the slot.
c. Leave the piece to harden for a few minutes.
d. Insert the sensor on top of the putty and, in a see-saw motion, rock the sensor until
it lies 1 … 3 mm (0.04 … 0.12 in) below the road or runway surface.
Make sure that the sensor lies in line with the road or runway and that no side is
more than 3 mm (0.12 in) below the road or runway surface.
4. Use a steel stick or similar to gently push the sensor cable along the base of the slot.
5. Place the measured grout mix in a suitable container and mix properly.
Consult the grout manufacturer specifications for the suitable hardener/resin mixing
ratio. The final texture of the grout should be pourable, but not flowing.
6. Check the sensor positioning again. See step 3.d .
7. Pour the grout around the sensor head and along the length of the slot to the surface.
Use the trowel to move the grout in and around the slot. Overfill the slot to ensure that
there are no cracks between the hole and the road pavement.
