Application of Bituminous Material
Following the preparation and inspection of the pavement surface, the seal
coat material shall be applied at the specified rates. The bituminous
material shall be uniformly applied in a single pass of the distributor and
with either a double or triple lap spray over the surface to be sealed.
Building paper shall be spread on the surface for a sufficient distance
back from the ends of each application so that flow through the spray bar
may be started and stopped on the paper and so that all sprays will be
operating at the proper pressure on the surface to be sealed. Immediately
after the application, the building paper shall be removed. Spots missed
by the distributor shall be properly treated with bituminous material. No
smoking, fires, or flames other than the heaters that are a part of the
