STEEL COMB AND BROOM FINISH ON CONCRETE PAVEMENT

An evaluation was made of the broom finish and steel comb finish applied to a concrete pavement and the steel comb finish was determined to be the better of the 2 methods. The steel comb finish was applied transversely with a steel comb having tines 0.03 inches by 0.08 inches in cross section spaced at 1/2 inch. The depth of the grooves produced was approximately 1/8 inch. The width of the steel comb attachment was also eight feet. Among the advantages of using the steel comb finish are: the constant depths and a uniform finish; the comb finish can be made with one pass which inhibits mixing or incorporating of bleed water into the surface concrete; textures produced with the steel comb appear more durable than those produced by the broom. Foremen reported no significant noise difference after riding on the 2 types of rough finishes.
