SECTION 706 - MASONRY UNITS
706.01 Brick .
706.01.1 General . Brick shall have a fine-grained, uniform, and dense structure, and be
free of lumps of lime, laminations, cracks, checks, soluble salts, or other defects that may in any way impair the strength, durability, a ppearance or usefulness of the brick for the purpose intended. Bricks shall emit a clear, metallic ring when struck with a hammer.
706.01.2 Building Brick . Unless otherwise stipulated, building brick shall conform to
ASTM C 62, Grade SW.
706.01.3 Sewer and Manhole Brick . Unless otherwise stipulated, brick for sewer and
manholes shall conform to ASTM C 32, Grade SM.
706.02 Concrete Brick . Concrete brick shall conform to ASTM C 55, Grade N, Type I.
706.03 Concrete Masonry Blocks . Concrete masonry blocks may be rectangular or
segmented and, when specified, shall have ends shaped to provide interlock at vertical joints. The blocks shall conform to the requirements of ASTM C 139; or, for hollow blocks, to ASTM C 90, Grade N, Type I. Dimensions and tolerances shall be as specified.
706.04 Right-of-Way Markers .
706.04.1 General . Concrete right-of-way markers shall be constructed in conformity
with the details shown on the plans and shall meet the requirements hereinafter set forth. When more than 20% of the units in a lot is rejected, the entire lot will be rejected.
706.04.2 Manufacture .
706.04.2 1--Description . The exposed portion of the marker shall present a smooth,
uniform surface, free of honeycomb, chips, or other defects. The shape, dimensions, and placement of steel shall be in accordance with details shown on the plans. All letters, figures, or other markings shall be true to type and size shown on the plans, and shall be legible.
706.04.2 2--Materials . The materials used in the manufacture shall conform to the
following.
706.04.2 2.1--Cement . The cement used shall meet the requirements of Section 701.

Subsection 711.01.
706.04.2 2.4--Proportions . The concrete shall have a minimum cement factor of 1.25.
706.04.2 2.5--St rength Requirements . The strength of the right-of-way markers shall be
determined by the beam method. Under the beam method, a completed unit is loaded at the midpoint of an 18-inch span with three-edge bearing; the unit shall develop a strength of not less than 12,000 pounds, total load. Two specimens will be tested for each 200 units, or increment thereof; one to destruction and one to the ultimate load of 12,000 pounds. SECTION 707 - JOINT MATERIALS
