While being placed the concrete shall be vigorously vibrated, by the use of a mechanical isvibrating device, and spaded to eliminate voids or honeycomb pockets.. The concrete shall be especially *cell 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 cc:ntous. 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 mari.pulated 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 (k) 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 form and shape until it has entirely hardened.
