613.01 Description.
This Section shall cover the work of constructing Brick or Co ncrete Block Masonry in accordance with these specifications at the locations and to the dimensions, lines, and grades as shown on the plans or established.
613.02 Materials.
All materials shall conform to the requirements of Division 800, Materials. Speci fic reference is made to the following: Section 805 - Building Brick (Grade MW clay or shale brick unless otherwise specified on the plans or Concrete Brick and Concrete Block.) Section 611 - Mortar for Masonry.
613.03 Construction Requirements.
a.Brick Masonry . The foundation shall be constructed firm and dry. All brick shall be damp at the time of laying. Bricks shall be laid in courses in full, close, uniform joints of mortar. Adjoining courses shall break joints by one -half len gth as nearly as practicable. The courses shall be level in all places, except where otherwise directed. All exposed surfaces shall be smooth and clean and the tie joint shall not exceed 1/2 inch {13 mm} in width. Broken or chipped bricks shall not be used in the faces of the masonry. The joints shall be cleaned and pointed before the mortar sets. The exposed surfaces of the bricks shall not be smeared with mortar forced out of the joints or that used in pointing, but shall be kept clean and free from morta r stains. For straight masonry walls, at least one course in seven shall be a header course. No masonry work shall be done in freezing weather.
b.Concrete Block Masonry. When so specified on the plans and/or in the proposal, masonry walls may be construc ted of hollow concrete blocks instead of bricks. Applicable construction details shall be the same as for brick masonry.
c.Manholes, Inlets, and Catch Basins . Brick masonry for manholes, inlets, and catch basins shall conform to details shown on the plan s. Construction details shall be as specified in Subarticle 613.03(a). Where shown on the plans, the faces of these and similar structures shall be given a plaster coat. Mortar for this coat shall be of the same mix as used in laying the brick and the coat shall be not less than 1/4 of an inch {6 mm} in thickness. Before applying the plaster coat, the brick shall be thoroughly wetted and the surface allowed to dry sufficiently to insure proper bond of the plaster coat. Full mortar beds shall be provided for setting castings required by the plans. Castings shall be set carefully to the specified elevations.
613.04 Method of Measurement.
The quantity of Brick or Concrete Block Masonry will be measured in cubic yards {cubic meters} of completed and accepted mas onry, except that when the proposal specifies payment by the unit for manholes, inlets, and the like, measurement will be by the completed and accepted units.
613.05 Basis of Payment.
a.Unit Price Coverage . The number of cubic yards {cubic meters} of Bri ck Masonry or Concrete Block Masonry, measured as provided above, will be paid for at the respective contract unit prices for these items, which shall
614.01 Description.
be payment in full for excavating except as specified in Section 214, laying, backfilling and for all materials, equipment, tools, labor, and incidentals necessary to complete the work. Manholes, inlets, catch basins, and the like will be paid for as specified in Section 620.
b.Payment will be made under Item No .: 613-A Brick Masonry - per cubic yard {cubi c meter} 613-B Concrete Block Masonry - per cubic yard {cubic meter} SECTION 614 SLOPE PAVING
614.01 Description.
This Section shall cover the work of paving with concrete any fill or cut slopes as sh own on the plans or designated. The slope paving shall be laid to line, grade, and dimensions shown on the plans or directed. Slope paving shall include, but not be limited to, paving of slopes at bridge ends, under grade separation structures, concrete sl ope drains, paving of side ditches, median ditches, special ditches, and other designated areas for control of erosion. Slope paving shall include wire mesh or other type of reinforcement when and as shown on the plans.
614.02 Materials.
The concrete shall meet the requirements of Section 501. Consideration will be given to the use of local or manufactured fine aggregate meeting the requirements of Section 826; if approved, the aggregate proportions shall be varied as directed. Steel reinforcement shall me et the appropriate requirements of Section 835. Joint filler and sealers shall meet the appropriate requirements of Section 832.
614.03 Construction Requirements.
The slope to be paved shall be uniformly dressed and compacted with mechanical tampers to the satisfaction of the Engineer before placing the concrete. Where grading has been completed under another contract and regrading is necessary to obtain correct grades for the slope paving, such regrading shall be considered incidental to the placement of the slope paving and no measurement or direct payment for such will be made. The concrete shall be mixed, placed, and cured in accordance with the requirements of Section 501, which is applicable to this work. Weep holes approximately 3 inches {75 mm} in diameter shall be placed in alternate runs of the pavement where deemed necessary by the Engineer. After placing, the concrete shall be finished smooth and unless otherwise directed, when partially set, shall be cut with a finishing tool as sho wn on the plans. Where reinforced concrete slope paving is specified on the plans, reinforcement shall be placed in accordance with details shown on the plans, and in conformity with requirements of Section 502. Unless otherwise shown on the plan details, joints for slope paved areas shall be in accordance with the following:
a.Contraction Joints. This type joint is essentially provided to control cracking and may be formed by tooling, sawing or other approved methods for not less than 1/5, nor more then 1/4 the depth of the concrete. Except for sawed joints, all joints shall be finished with a 1/4 inch {6 mm} edging tool. For flumes and ditch paving not adjacent to other paving, the transverse contraction joint spacing shall be as approved by the Engineer, but generally not in excess of 30 feet {9 m}. Longitudinal contraction joints may be ordered by the Engineer for paving widths in excess of 30 feet {9 m}, but are not to be placed where joint cracking will cause excessive seepage into subgrade. For media ns, islands, and ditches paved adjacent to curbs, gutters, or other paving, transverse contraction joint spacing shall be located wherever possible so as to line up with existing joints. Longitudinal contraction joints may be ordered for paving widths in excess of 20 feet {6 m} to control pavement cracking.
b.Construction Joints. The use and spacing of construction joints shall be as approved by the Engineer, consistent with the planned contraction and expansion joints for the paved area and the Contracto r's paving plan. The
