Before laying the new asphalt pavement, a water pipe was laid on the section of the road from the fork of Olgetti-Armkha to the Obanhi plant (diameter - 110 mm, 16 atmospheres, length - 550 meters).
Supplemented sand under and around the water pipe so that the sandy stone soil, which prevails in this area, did not damage the pipe.
Also over the sand pillow laid signal tape.
