(c) 
Brick paving.
[1] 
All brick pavers shall be laid in the pattern shown on the plans or as directed by the Engineer to provide a uniformly even surface. Joints shall be handtight unless otherwise specified. No brick pavers shall be laid or grouted in freezing weather.
[2] 
A dry mixture of mortar for brick paving shall be swept over the brick pavers until the joints are completely filled and the joints lightly fogged with water. Brick pavers shall be cleaned of excess mortar and joints finished prior to the mortar setting up. All brick paving shall be kept moist for four days after filling the joints with mortar. After the four-day curing period, removal of the remaining mortar film may be accomplished by the use of a light acid wash [10% solution of hydrochloric or muriatic acid] followed by flushing clean with water or as approved by the Engineer. Care shall be taken to avoid the use of acid in areas where runoff could damage trees or other vegetation.
[3] 
All brick pavers used over tree pits shall be laid in a three-inch bed of cushion sand with sandfilled joints.
[4] 
Brick paving (sand setting bed). Brick pavers shall be laid in a properly compacted three-inch bed of cushion sand over the specified subgrade.
[5] 
Brick paving (mortar setting bed). Brick pavers shall be laid in a bed of mortar with a minimum thickness of one inch over the specified concrete or bituminous subgrade.

Brick paving (bituminous setting bed). Brick pavers shall be laid in a three-fourths-inch thick bituminous setting bed over the specified concrete or bituminous subgrade. The setting bed shall consist of asphalt cement meeting the requirements outlined in either Section 702-02 or Section 702-03 mixed with fine aggregate meeting the requirements of Section 703-01. The asphalt cement shall be 7.0% of the total batch weight. The mix shall be heated to approximately 325° F.). A coating of neoprene-modified asphalt adhesive shall be applied by mopping, squeegeeing or troweling over the top surface of the setting bed to provide bond under the bricks.
[7]
