that when consolidated and finished, the surface of the pavement will be at
the required elevation. In addition to previously specified complete
coverage with handheld immersion vibrators, the entire surface shall be
tamped with the strike-off and tamping template, and the tamping operation
continued until the required compaction and reduction of internal and
surface voids are accomplished. Immediately following the final tamping of
the surface, the pavement shall be floated longitudinally from bridges
resting on the side forms and spanning but not touching the concrete. If
necessary, additional concrete shall be placed and screeded, and the float
operated until a satisfactory surface has been produced. The floating
operation shall be advanced not more than half the length of the float and
then continued over the new and previously floated surfaces.

Texturing
**************************************************************************
NOTE: Designer must select type of texturing
desired, retain that subparagraph, and delete the
others. A genuine effort should be made to
determine the type of texturing, if any, desired by
the using service. If no guidance is given, the
usual default method should be burlap drag. Edit
bracketed phrases as appropriate. For Air Force
airfield paving projects, do not specify artificial
turf, wire comb, or surface grooving textures. Use
UFGS 02986, Grooving for Airfield Pavements, to
specify saw-cut grooves. If other than a burlap drag
textured finish is required, add the appropriate
paragraph(s) as shown below. Spring tine grooving
is limited to use on roads and streets only.
**************************************************************************
Before the surface sheen has disappeared and before the concrete hardens,
the surface of the pavement shall be given a texture as described herein.
After curing is complete, all textured surfaces shall be thoroughly power
broomed to remove all debris.
3.6.5.1
Burlap Drag Surface
Surface texture shall be applied by dragging the surface of the pavement,
in the direction of the concrete placement, with an approved burlap drag.
The drag shall be operated with the fabric moist, and the fabric shall be
cleaned or changed as required to keep clean. The dragging shall be done
so as to produce a uniform finished surface having a fine sandy texture
without disfiguring marks.
3.6.5.2
Artificial Turf Drag Surface
Artificial turf texture shall be applied by dragging the surface of the
pavement in the direction of concrete placement with an approved full-width
drag made with artificial turf. At least 600 mm 2 feet of the artificial
turf shall be in contact with the concrete surface during texturing
operations. The corrugations shall be uniform in appearance and
approximately 2 mm 1/16 inch in depth.
3.6.5.3
Broom Texturing
Surface texture shall be applied using an approved mechanical stiff bristle
broom drag of a type that will uniformly score the surface transverse to
