(A) The pavement shall be struck off and consolidated with a mechanical finishing machine or by hand- finishing methods. When a mechanical finishing machine is used, the concrete shall be struck off at such a height that after consolidation and final finishing, it shall be at the elevation as shown on the plans.
(B) The finishing machine shall be provided with a screed which will consolidate the concrete by pressure, vibration or both. The concrete shall be brought to a true and even surface, free from rock pockets. The edge of the screeds along the curb line may be notched out to allow for sufficient concrete to form the integral curb. Hand-finishing tools shall be kept available for use in case the finishing machine breaks down.
(C) When hand-finishing is used, the pavement shall be struck off and consolidated by a vibrating screed to the elevation as shown on the plans. When the forward motion of the vibrating screed is stopped, the vibrator shall be shut off; it shall not be allowed to idle on the concrete.
(1) Scraping and straight-edging.
(a) The pavement may be required, by the inspector, where applicable, to be scraped with a straight-edge equipped with handles long enough to permit it to be operated from the edge of the pavement.
(b) When irregularities are discovered, they shall be corrected by adding or removing concrete. All disturbed places shall be floated with a wooden or metal float not less than three feet long and not less than six inches wide and again straight-edged.
(2) Edging. Before final finishing is completed and before the concrete has taken its initial set, the edges of the slab and curb shall be carefully finished with an edger, having a radius of one-eighth inch.
(3) Final surface finish. A burlap drag shall be used as the final finishing method for concrete pavement. The drag shall be at least three feet in width and long enough to cover the entire pavement width. It shall be laid on the surface of the pavement and dragged forward in the direction in which the pavement is being laid. The curb shall have the same final finish as the pavement.
(4) Texture, grades. The final surface of the concrete pavement and curb shall have a uniform gritty texture, free from excessive harshness and true to the grades and cross-sections shown on the plans. The inspector may require changes in the final finishing procedures as required to produce the desired final surface texture.
