Where the soil in the alley consists of sand or sandy soil incapable of compaction by rolling or tamping, said compaction shall be accomplished by thoroughly flooding the subgrade. After being prepared in the above manner the subgrade shall be so maintained until the pavement has been placed thereon. CRECKING ATRD ACCEPTANCE: Immediately before the pavement is laid, the subgrade shall be checked by means of an approved template, shaped on the under side to conform to the lower surface of the finished pave- ment, or by a method of testing approved by the Board of Local Improve- ments. All high places shall be removed to true grade and any low places filled with sandy soil and rolled or hand tamped until smooth and firm, The subgrade shall be checked and completed in accordance with these re- quirements for a distance of not less than one hundred (100) feet in advance of the pavement. If hauling over the subgrade after it has been finished and checked as specified results in ruts or other such ob- jectionable irregularities, the contractor shall reroll or hand tamp the subgrade and place it in smooth and satisfactory condition before the pavement is deposited upon it. If the condition of the subgrade is such that it cannot be placed in satisfactory condition to receive the pavement, paving shall be stopped by the Engineer unless the contractor provides and hauls over suitable trackways or uses other means for the protection and maintenance of the subgrade. The cost of subgrade pre- paration and all excavation and replacement required by these specificat- ions shall be included in the unit price bid for Special Excavation. SEWER CONNECTIONS: All existing connections to the present sewer shall be protected against damage during the construction of this pro- posed improvement.

CONTRACTION JOINTS: Sawed contraction joints or other type of contraction joints vihich may be approved by the Engineer, shall be placed throughout the entire improvement across the concrete pavement at right angles to the center thereof at intervals of twenty-five (25) feet between expansion joints and in accordance with the detail shown on plans. Furnishing all 'labor, equipment, and materials for the installa- tion of said contraction joints including dowel bar assembly shall not be paid for directly, but will be considered incidental to the con- struction of the Portland Cement Concrete Pavement. - 5 - MIXING AIM PLACING CONCRETE: Concrete shall be mixed and placed in accordance with the requirements of Section 408 of the "Standard Specifications", insofar as the same may apply. While being placed the concrete shall be vigorously vibrated, by the use of a mechanical vibrating device, and spaded to eliminate voids or honeycomb pockets. The concrete shall be especially well spaded and tamped against forms and bulkheads. The concrete shall be struck off, so that the upper surface shall conform to and be sufficiently higher than the contour. herein specified for the upper surface of the finished pavement, to give the specified thickness of pavement herein required. The strike board shall be moved forward with a combined longitudinal and transverse motion, and so manipulated as to tamp the concrete thoroughly. A slight excess of material shall be kept in front of the cutting edge at all times. The entire area of the pavement shall be struck off and tamped, so executed as to insure maximum compaction. FINISHING CONCRETE: After the vibrating and the tamping has been completed, the pavement shall be rubbed smooth of all ridges and de- pressions and brought to a true and even surface by the use of wooden floats. A split float, shaped on the under side to conform to the contour of the pavement, shall be used for finishing the concrete on both sides of the longitudinal joints, hereinbefore specified. The edges adjoining the transverse expansion joint and the form, shall be tooled with an edging tool, having a radius of one -quarter Q) inch, After the floating has been completed, the surface of the pavement shall be tested with a notched straight edge, ten (10) feet in length.. This straight edge shall be placed over the transverse joints and be- tween the same at frequent intervals, parallel to the center line of ; the pavement and moved across from side to side. Any variation in excess of one -eighth (1/8) inch above or below the general established contour of the pavement shall be rubbed with a long handled float and the irregularities corrected until the straight edge shall show a bearing for its entire length. Workmen shall not walk on freshly laid concrete and no one shall be allowed on the concrete after it has been worked into fors and shape until it has entirely hardened. The entire surfacing of the concrete pavement shall be done from a bridge, not less than one (1) foot in width which shall not come in contact with the concrete pavement at any point. Two (2) of said bridges shall be provided for each concrete mixing gang. Two bridges shall be maintained in constant readiness to be immediately moved into position, to provide access for finishing, tooling and edging joints, adjusting filler and refinishing damaged portions of the finished surface. , PROTECTION AND CURING: Protection and curing shall comply with the requirements of Section 408 of the "Standard Specifications". - 6 - Alley Paving STORM SEWERS For the purpose of carrying off storm waters from the surface of the pavement herein provided to be constructed, storm sewers of vit- rified clay sewer pipe shall be laid as hereinafter specified.
