cobble stones, Portland cement concrete, bituminous concrete, or other such materials or combina- tions thereof, in reasonably close conformity with the lines and grades indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. 711.02 MATERIALS. Gravel Borrow base shall conform to the requirements of Subsection
M.01.02 of these Specifications. Concrete shall be Class A(AE) and shall otherwise conform to the applicable requirements of SECTION 601; PORTLAND CEMENT CONCRETE of these Specifications. Bituminous Concrete shall conform to the requirements for Class I-2, surface course material, as set forth in Subsection M.03.01 of these Specifications. Cobblestones shall conform to the requirements of Subsection M.10.05 of these Specifications. Cement Mortar shall meet the requirements of Subsection M.04.03.5; Mortar , of these Specifications. Bedding Sand shall be natural or manufactured material conforming to the requirements of AASHTO M6. 711.03 CONSTRUCTION METHODS. 711.03.1 Excavation. Excavation for paved waterways shall be carried forth in accordance with the applicable requirements of SECTIONS 202 or 205 of these Specifications.
711.03.2 Plain Cobble Paving. A layer of bedding sand shall be placed upon a prepared
subgrade. This course shall be sufficiently thi ck to bring the cobblestones, which will be embedded in it, to the proper tamped grade and cross section, all as indicated on the Plans. The cobblestones shall then be placed. Each stone is to be rammed to an unyielding foundation. The work shall proceed from the sides toward the center, keeping the sides in advance of the center. After the stones have been set, all joints and cavities shall be filled with bedding sand. Stones shall be carefully and thoroughly rammed until no further settlement occurs. During the ramming, the joints shall be kept full of clean fine sand. If, from any cause, the stones shall have been disturbed and left uneven, they must be repl aced by the Contractor at no additional cost to the State. The finished surface shall be smooth, even, and reasonably close to the finished line, grade and cross sections. 7−23Concrete headers or stone headers shall be installed in reasonably close conformity to the lines and grades indicated on the Plans, or as directed by the Engineer. 711.03.3 Grouted Cobble Paving. A layer of bedding stone shall be placed upon a prepared subgrade. This course shall be sufficiently thick to bring the stones to the proper grade and cross section. The cobblestones shall then be placed. The work shall proceed from the sides toward the center, keeping the sides in advance of the center. After the stones have been set, all joints and cavities shall be filled with bedding stone to such a height, that after tamping, the joints shall be filled to within 4 inches of the top. After the stones are thoroughly rammed and at the proper grade, the cement mortar shall be poured and broomed into the spaces between and over the stones. This operation shall be continued until the mortar is flush with the tops of the stones. Concrete headers or stone headers shall be installed in reasonably close conformity to the lines and grades indicated on the Plans, or as directed by the Engineer. 711.03.4 Bituminous Mixture Paving. A layer of gravel borrow shall be placed upon a prepared subgrade. Unless otherwise indicated on the Plans, this course shall be 6 inches thick such that it conforms to the proper grade and cross section after compaction. The bituminous mixture shall be spread on the gravel borrow base prepared as herein specified and compacted by tamping or rolling to a finished depth of 3 inches, or such other depth as may be indicated on the Plans. The finished surface shall reasonably conform to the proposed lines, grades and cross sections. 711.03.5 Cement Concrete Paving. A layer of gravel borrow shall be placed upon a prepared subgrade. Unless otherwise indicated on the Plans, this course shall be 6 inches thick such that it conforms to the proper grade and cross section after compaction. The cement concrete shall be placed on the gravel borrow base to the designated thickness. The finished concrete surface shall reasonably conform to the proposed lines, grades and cross sections. Expansion joints, as required, shall be constructed at the indicated locations and to the required dimensions. Concrete headers or stone headers shall be install ed in reasonably close conformity with the lines and grades indicated on the Plans, or as directed by the Engineer. 711.04 METHOD OF MEASUREMENT. "Paved Waterways" of the various types indicated on the Plans will be measured by the number of square ya rds of each such type actually provided in accordance with the Plans and/or as directed by the Engineer. (Widths and lengths measured in the horizontal plane.) 711.05 BASIS OF PAYMENT. The accepted quantities of the various types of "Paved Waterways" indicated on the Plans will be paid for at their respective contract unit prices per square yard as listed in the Proposal. The prices so-stated consti tute full and complete co mpensation for all labor, materials and equipment, including excavation (except "Rock Excavation" or "Rock Excavation/Mechanical"), concrete or stone headers, if required, and for all incidentals required to finish the work, complete and accepted by the Engineer. 7−24 "Trench Excavation - Rock,” "Trench Rock Excavation/Mechanical,” or "Channel Excavation Rock" will not be included in the contract unit prices for the various types of paved waterways but will be paid for separately as set forth in SECTIONS 202 or 205 of these Specifications. SECTION 712 WATER AND GAS GATE BOXES
712.01 DESCRIPTION. This work consists of removing and disposing existing water or gas gate
boxes, and subsequently providing new water or gas gate boxes at the locations indicated on the Plans or as directed by the Engineer, all in accordance with these Specifications. 712.02 MATERIALS. 712.02.1 Castings. Iron castings shall conform to the requirements of Subsection M.05.04.9, Para. f , of these Specifications.
712.02.2 Fabrication. The Contractor shall provide documentation to the effect that water and gas
gate boxes conform to the requirements of the respective manufacturers, utility companies and municipalities.
a.Finish. The gate boxes, including covers, shall be thoroughly cleaned and thereafter all surfaces shall be coated, painted or dipped in an asphalt or bituminous base paint or coating. 712.03 CONSTRUCTION METHODS. 712.03.1 Removal of Existing Boxes. The existing gate valve boxes are to be carefully removed so as not to damage or disturb the valves or appurtenant fittings which are to remain. After the gate boxes have been removed, they shall become the property of the Contractor and legally disposed of. 712.03.2 Installation. The boxes shall be set to the proposed line and grade as indicated on the Plans. Once the boxes are set, the Contractor shall take sufficient care not to disturb them. All installations shall be subject to the approval of the applicable gas and/or water company. The boxes shall be carefully fitted together to the valve and securely held during backfilling. The backfill material shall be thoroughly tamped in place. The boxes shall be constructed as to prevent the separation of the upper section from the lower section and to prevent the upper section from turning when removing the lid. 712.04 METHOD OF MEASUREMENT. "Water Gate Boxes" and "Gas Gate Boxes" will be measured by the number of such assemblies actually installed in accordance with the Plans and/or as directed by the Engineer.
