Fabick epoxy resin is hazardous material. Wear protective clothing, gloves, and a safety helmet.
To create a constant thermal compatibility around each sensor, the block must be consistent. The space around the sensor allows free flow of grout to envelope the sensor without air bubbles. An oversize hole or too much grout around the sensor weaken the bond and stability.
Use the installation cap to install DRS511 2 mm (0.08 in) below the grade of the pavement surface. The sensor must sit below the normal grade of the road to enhance the sensor capabilities.
  1. Uncoil the sensor cables and place them in the slot.

    Check that the DTS12G sensor is not covered.

  2. Insert the putty to the bottom of the slot.
    1. 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.
    2. Shape the piece into a cone and place it at the bottom of the slot.
    3. Leave the piece to harden for a few minutes.
    4. Insert the sensor on top of the putty and, in a see-saw motion, rock the sensor until the installation cap is on the same level as the road or runway surface.
  3. Push the sensor cable carefully along the base of the slot.
  4. Verify with a spirit level that the top of the installation cap is flush with the pavement.
  5. Partition the sensor cut and the slot run at the joining point before applying Fabick epoxy resin to contain the material within the sensor area.
    Place a dam 2.5 cm (1 in) inside the slot to prevent Fabick epoxy resin pouring out.
  6. Set up the Fabick dispenser and apply the epoxy resin slowly from one end to allow all air to escape.
    If you apply the epoxy resin too quickly, large bubbles may form, and there will be unwanted gaps in the epoxy.
    Fill up to the level of the top of the installation cap and hole. Do not overfill.
  7. Wait for 2 minutes for the epoxy resin to start setting.
  8. At 3 minutes, touch the surface with a screwdriver to determine if the epoxy resin is hardening.

    If the epoxy resin sticks to the screwdriver, do not pull further. Let it set for another 30 seconds and try again.

  9. When there is no movement in the grout, make sure that the installation cap is still flush with the pavement.
  10. Scrape or brush away excess, if any.
    CAUTION Be careful not to gouge into the material. It is still soft and liquid and damaging it can affect installation quality.
  11. At 4 minutes, insert a small flat head screwdriver under a corner of the installation cap and leverage off at 45° angle to remove it.
    Be careful not to damage the grout.

    The installation cap peels off and the sensor appears 3 mm (0.12 in) below grade.

  12. When the material is still warm but solid, remove the shine from the set grout gently with a wire brush so that the grout blends with the road surface.
    CAUTION Be careful not to scratch the sensor.
