CITY OF SANTA ANA APPENDIX I PROJECT NO.: XX-XXXX PROJECT TITLE • Compressive strength at 7 days: 2500 p.s.i. min. All cement to be used or furnished on this Project shall be Type II low alkaline Portland cement conforming to ASTM C150. Prior to the start of construction, the Contractor shall furnish to the Engineer laboratory test data for the particular mix design he will use. The data will include the following: A. A detailed concrete mix design including the type and amount of cement used; complete gradation and source of the aggregate used; the amount of water used; and any proposed admixtures. B. Flexural strength test data for the same batch of concrete used in A above showing the compressive strength of the concrete at 3, 7, and 28 days. Section 302-6.4.2 entitled "Tamping" of the Standard Specifications shall be modified by adding the following: The outer edge of the gutter shall not be used as a side form for the mechanical tamper except where existing gutter is to remain as shown on the construction plans. Concrete pavement for bus pads shall be installed monolithic with the curb and gutter and shall be accomplished in accordance with City of Santa Ana Standard Plan No. 1108. Section 302-6.4.4 entitled "Final Finishing" of the Standard Specifications shall be modified as follows: Delete all reference to wetted burlap. Final finish of the surface shall be textured by stiff broom process that will produce scoring perpendicular to the centerline of the street, performed at a time and in a manner to produce a hardened surface have a coefficient of friction of not less than 0.38 as determined by California Test 342. Curing to be applied immediately following broom process. Joints in the concrete pavement shall be constructed as described in Section 302-6.5 of the Standard Specifications except as modified herein. Sawing of the joints shall begin as soon as the concrete has hardened sufficiently to permit sawing without excessive raveling, usually 4 to 24 hours per Engineer's directions. If necessary, the sawing operations shall be carried on both day and night, regardless of weather conditions. All joints shall be sawed before uncontrolled shrinkage cracking occurs. A standby saw shall be available in the event of breakdown. All weakened plane joints shall be saw cut to a depth equal to one fourth of the pavement thickness. Longitudinal joint spacing shall be at 10' minimum and 15' maximum on either side of centerline joint. Transverse joint spacing shall be at 10' minimum and 15' maximum for pavement, curb and gutter.
