Compacting and bonding. After completing the vibration of the
fine material, the surface of single-layer construction, or the surface
of each layer of multilayer construction, shall be sprinkled with
water and rolled. All excess screenings forming in piles or cakes
upon the surface shall be loosened and scattered by sweeping, exercising
care that the fine material is not removed below the top of the coarse
aggregate. On the surface of single-layer construction or the top
layer of multilayer construction, the sprinkling and rolling shall
be continued and additional screenings applied where necessary until
all voids are filled and until a slight wave of grout forms in front
of the roller wheels. Brooms attached to the roller, and hand brooms,
shall be used to distribute the grout uniformly into the unfilled
voids. After the wave of grout has been produced over the entire section
of the base course, this portion shall be left to dry. The surface
shall be sprinkled and rerolled as required to bond it thoroughly
and to secure a satisfactory surface. The quantity of screenings and
water used shall be sufficient to produce a smooth, hard monolithic
surface.
