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} 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
615.02 Materials.
edges of all construction joints shall be finished with a 1/4 inch {6 mm} edging tool unless otherwise ordered by the Engineer.
c.Expansion Joints. Unless otherwise shown by plan details or directed by the Engineer, expansion joints 3/8 of an inch {9 mm} wide shall be placed as follows: • Where the slope paving joins drainage structures and other rigid structure supports. • To line up with expansion joints of adjoining pavement curbs, gutters, etc., but in no instance more than 80 feet {2 4 m} between joints. • Where continuous runs of slope paving are 80 feet {24 m} or longer, transverse expansion joints shall be provided; one joint for each additional 80 feet {24 m}, or fraction thereof, of length. • Where slope paving is confined longitudina lly by other concrete units and the width of the slope paving is in excess of 15 feet {5 m}, one longitudinal expansion joint will be required for each additional 15 feet {5 m}, or fraction thereof, of width. • Paved islands of 200 square feet {19 m²} or les s may be poured as a monolith if approved by the Engineer. • Expansion joints shall be formed using a filler and sealer specified in Articles 832.01 and 832.02. • Unless shown otherwise by plan details, the joint filler shall be from the bottom of the slope paving to 1 inch {25 mm} from the top; the sealer shall be 3/4 of an inch {19 mm} thick and shall be recessed 1/4 of an inch {6 mm} from the top.
614.04 Method of Measurement.
Slope paving will be measured in cubic yards {cubic meters} of paving, complete in place. Regrading in excess of 12 inches {300 mm} depth as described in Article 614.03 will be measured and paid for as Structure Excavation, Section 214.
614.05 Basis of Payment.
a.Unit Price Coverage . The accepted quantity as determined above shall be paid for at the contract unit price for slope paving, which shall be payment in full for all excavation, backfilling, compacting slopes to be paved, disposal of surplus material, furnishing all materials, mixing, curing, hauling, and placing all materials, and for all labor, equipment, tools, and incidentals necessary to complete the item.
b.Payment will be made under Item No .: 614-A Slope Paving - per cubic yard {cubic meter} 614-B Reinforced Slope Paving - per cubic yard {cubic meter} SECTION 615 GROUTED RUBBLE SLOPE DRAIN
615.01 Description.
This Section shall cover the work of constructing gutter slope drain of grouted rubble masonry in accordance with the plans and these specifications and to the established lines, grades, and cross section shown on the plans and designated.
615.02 Materials.
a.General . The materials shall conform to the requirements of Division 800, Materials. Specific reference is made to Subarti cle 812.0l(b), Type II, Masonry Stone.
b.Grout . Grout shall meet the requirements of Section 611, Mortar for Masonry, except that it shall be of wetter consistency to flow as indicated in Subarticle 615.03(c).
c.Base Course Material . Material shall be taken from sources shown on the plans or other approved sources of equal quality.
