3. After the concrete has been placed and consolidated, the surface of the concrete shall receive a preliminary finish. The preliminary finish shall consist of carefully striking off the surface of the concrete with a template or strike board until a uniform surface is obtained. The form on the face of paving shall not be removed while the concrete is sufficiently plastic to slump.

4. Prior to removal of the forms, the surface shall be finished true to grade by means of a straight edge float, operated over the surface of the concrete. Form clamps shall be so constructed as not to interfere with the operation of this float.

5. The finished surface shall receive a uniformly coarse traverse scored texture by drawing a nylon broom across a floated finish. Lines shall be of scored of uniform depth within the concrete surface, straight, parallel and at right angles to the direction of traffic, unless indicated otherwise. The finished broom surface shall be free from blemishes, humps, sags or other irregularities.

6. Any major defects found in the concrete paving shall be repaired by removing and replacing the entire unit between score lines or joints, as directed by the City’s Representative.

7. All discolored concrete paving shall be cleaned to a uniform color. Repairs and cleaning of new concrete shall be at the expense of the Contractor.

Yard waste compost free of contaminants with pH of 5.5-8.0, minimum organic content of 250 pounds per cubic yard of compost (minimum 50% of compost’s dry weight, TMECC 05.07-A), 35-60% moisture content, salinity measured on the saturation extract solution shall not exceed 8.0 dS/m, maximum 4.0 dS/m Ece, and a minimum of 90% of the material by weight shall pass a ½" screen. Material passing the ½" screen shall meet the following criteria:

Sieve Designation Percent Passing 9.51 mm (3/8”) 85-100% 2.38 mm (No. 8) 50-80% 500 micron (No. 35) 0-40%
