than 8 inches {200 mm} in thickness and from 5 to 10 feet {1.5 to 3 m} long. The sections may be cast in place or precast and set in place in full mortar beds.

Pointing shall not be done in freezing weather or when the stone contains frost. Joints not pointed at the time the stone is laid shall be wet with clean water and filled with mortar. The mortar shall be well driven into the joints and finished with an approved pointing tool. The wall shall be kept moist while pointing is being done and in hot dry weather the pointed masonry shall be protected from the sun and kept wet for a period of at least three (3) days after the mortar has set, or be cured as provided by Subarticle 450.03(m). After the pointing is completed and the mortar set, the wall shall be satisfactorily cleaned and left in a neat and workmanlike condition.

612.04Measurement

Accepted Rubble Masonry will be measured complete in place, and the volume actually constructed within the neat lines of the work shown on the plans or designated will be computed in cubic yards {cubic meters}.

612.05Basis of Payment

The accepted volume of rubble masonry measured as above described will be paid for at the respective unit prices bid per cubic yard {cubic meter} for Coursed Rubble Masonry, Uncoursed Rubble Masonry, and Rustic Rubble Masonry, complete in place, which shall be payment in full for all material, equipment, tools, labor and incidentals necessary for the satisfactory completion of the work.

Concrete used in conjunction with the Rubble Masonry will be paid for as provided under Minor Structure Concrete, Section 620.

612-A Type Rubble Masonry - per cubic yard {cubic meter} BRICK AND CONCRETE BLOCK MASONRY

613.01Description

This Section shall cover the work of constructing Brick or Concrete Block Masonry in accordance with these specifications at the locations and to the dimensions, lines, and grades as shown on the plans or established.

613.02Materials

All materials shall conform to the requirements of Division 800, Materials. Specific 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.

613.03Construction Requirements

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 length 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 mortar 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. SLOPE PAVING 492

When so specified on the plans and/or in the proposal, masonry walls may be constructed of hollow concrete blocks instead of bricks. Applicable construction details shall be the same as for brick masonry.

Brick masonry for manholes, inlets, and catch basins shall conform to details shown on the plans. 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 ensure 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.

613.04Method of Measurement

The quantity of Brick or Concrete Block Masonry will be measured in cubic yards {cubic meters} of completed and accepted masonry, 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.

613.05Basis of Payment

The number of cubic yards {cubic meters} of Brick Masonry or Concrete Block Masonry, measured as provided above, will be paid for at the respective contract unit prices for these items, which shall 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.

613-A Brick Masonry - per cubic yard {cubic meter} 613-B Concrete Block Masonry - per cubic yard {cubic meter} SLOPE PAVING

614.01Description

This Section shall cover the work of paving with concrete any fill or cut slopes as shown 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 slope 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.

614.02Materials

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 meet the appropriate requirements of Section 835. Joint filler and sealers shall meet the appropriate requirements of Section 832.

614.03Construction 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
