    I would like to know if sweeping loose aggregates is a standard pavement maintenance works for road and how to find its specifications.

    The Texas Department of Transportation has an Item in their standard specifications for "Cleaning and Sweeping Highways"  (Item 738,  This is probably used most often when the Department contracts for this service, rather than having their own maintenance forces doing this.  Sweeping removes dust/dirt which can cause a slick surface in wet conditions, minimizes clogging of drainage inlets, and improves the quality of stormwater runoff.

    During construction, sweeping is routinely done to clean the pavement surface before applying a tack coat or interlayer as part of resurfacing.  A new surface will not adhere to an existing surface coated with dust/dirt.  It is also part of a chip sealing operation, in which a light brooming is done to remove excess material after the stone chips have been rolled before opening to traffic.
