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} 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.
615.03 Construction Requirements.
615.03 Construction Requirements.
a.Foundation . The foundation shall be formed at a depth of not less than 8 inches {200 mm} below and parallel to the finished surface of t he slope drain. All soft or other unsuitable material shall be removed, and the foundation shall be compacted and finished to a smooth, firm surface.
b.Bedding Stone . The approved foundation material shall be prepared to form a bed as provided by the pla ns. The slope drain stone shall be bedded in the foundation perpendicular to the finished surface, flat face up, with the longest dimension parallel to the slope drain. The stone shall be fitted and laid in close contact and shall break joints satisfactori ly. Each stone shall be tamped into place until the stones are firm and the surface conforms to the finished grade and cross section.
c.Finishing . While the slope drain stones are being tamped, the spaces between stones shall be filled and rammed with ba ckfill material selected from unclassified excavation, to within 3 inches {75 mm} of the top and any irregularities in the slope drain corrected. The cement grout shall be poured and broomed into the spaces between and over the stones. This operation shall be continued until the grout remains flush with the tops of the stones. The slope drain shall be protected by wet burlap until the grout hardens, then kept moist for at least three days after grouting. No grout shall be poured in freezing weather.
615.04 Method of Measurement.
Accepted Grouted Rubble Masonry Slope Drain will be measured in square yards {square meters} complete in place, along the finished surface both longitudinally and transversely, and computed to the nearest 0.1 square yard {0.1 m²}.
615.05 Basis of Payment.
a.Unit Price Coverage . The accepted Grouted Rubble Slope Drain will be paid for at the contract unit price per square yard {square meter}, complete in place, which shall be payment in full for excavating and preparing the foundatio n bed, placing and grouting the stone and for furnishing all materials, tools, labor, and incidentals necessary to complete the work.
b.Payment will be made under Item No .: 615-A Grouted Rubble Slope Drain - per square yard {square meter} SECTION 616 SOIL CEMENT FLUMES
616.01 Description.
This Section shall cover the work of constructing soil cement flumes at locations designated in accordance with details shown on the plans.
616.02 Materials.
All materials shall conform to the requirements of Division 800, Materials. Specific reference is made to the following: Cement, Section 815. Water, Subarticle 807.01(b).
