Method of exposing a utility buried below a roadway and a bore hole cleaning device

A method of removing dirt surrounding a utility buried under a roadway comprising:

• inserting a vacuum nozzle into an access hole in a roadway above a buried utility, a spray device is connected to the vacuum nozzle, and the spray device having at least one pressurized water nozzle or compressed air nozzle;
• applying vacuum to the vacuum nozzle by source of vacuum to vacuum away dirt surrounding the buried utility to expose the buried utility;
• spraying at least one of pressurized water from the pressurized water nozzle or compressed air from the compressed air nozzle into the dirt to loosen the dirt surrounding the buried utility;
• after removing the dirt surrounding the buried utility to expose the buried utility, cutting a microtrench in the roadway using a microtrencher so that the microtrench crosses the exposed buried utility and does not damage the exposed buried utility;
• laying optical fiber, innerduct or microduct in the microtrench;
• and
• filling the microtrench and hole with a fill material to cover and protect the optical fiber, innerduct or microduct.
