11. Allow to cure.
The cure time depends on the air temperature as well as the filling material used. As the
final curing takes place, use a wire brush to remove any excess filling material from
around the sensor head as well as to roughen the surface. This will best reflect the
surface tension of the surrounding road or runway.
To speed up the curing, sprinkle filler sand on top of the filling. This also prevents the
filling from spreading under car tires, if the road is opened for trac before curing is
finished.
12. Clean DRS511.
a. Remove the protective tape from the sensor head.
b. Clean the tape residue from the sensor head with sanding paper (grade 800).
c. Finalize by cleaning the sensor with a wet wipe.
13. Lead the sensor cable to the enclosure.
a. Pull the cable through the plastic protective ducting.
b. Place the duct into the trench that leads to the enclosure.
The cable is cut to length, but if you have a manhole available, you can leave tooling
allowance in the cable and bury the excess in the hole.
c.
Backfill the trench.
