CITY OF SANTA ANA <br />SPECIFICATIONS <br />PROJECT NO. 11 -6416 <br />SEVENTEENTH STREET WATER MAIN IMPROVEMENTS <br />friction of not less than 0.38 as determined by California Test 342. Curing to be applied <br />immediately following brooming. <br />Joints in the concrete pavement shall be constructed as described in Section 302 -6.5 of the <br />Standard Specifications except as modified herein. Sawing of the joints shall begin as soon as <br />the concrete has hardened sufficiently to permit sawing without excessive raveling, usually 4 <br />to 24 hours per Engineer's directions. If necessary, the sawing operations shall be carried on <br />both day and night, regardless of weather conditions. <br />All joints shall be sawed before uncontrolled shrinkage cracking occurs. A standby saw shall <br />be available in the event of breakdown. All weakened plane joints shall be saw cut to a depth <br />equal to one fourth of the pavement thickness. Longitudinal joint spacing shall be at 10' <br />minimum and 15' maximum on either side of centerline joint. Transverse joint spacing shall <br />be at 10' minimum and 15' maximum for pavement, curb and gutter. Longitudinal joints shall <br />be aligned such that they will cross manholes and water valves at centerline if possible. <br />Transverse construction joints within 1' shall cross all manholes and water valves. Provide a <br />weakened plane joint around the perimeter of all utility vaults. Payment for cold joint <br />construction or weakened plane saw cutting shall be included in the PCC Construction Bid <br />Item and no additional compensation shall be allowed therefore. <br />The Cleanness Value requirement of Section 200 -1.4 shall be replaced with the following: <br />Tests <br />Cleanness Value <br />Individual Test <br />Moving Average <br />Test Method <br />California 227 <br />Requirements <br />70 min* <br />75 min* <br />The Sand Equivalent requirement of Section 200 -1.5.3 shall be replaced with the following: <br />Sand Equivalent <br />Individual Test <br />Moving Average <br />California 227 <br />70 min* <br />75 min* <br />Evaluation of Sand Equivalent and Cleanness Value results shall conform to the provisions of <br />Standard Specifications Subsection 400 -1.4. <br />Concrete shall be high early strength concrete, treated in accordance with section 201 -1 to <br />obtain 7 day compressive strength in 3 days. <br />Traverse joints shall match those of the adjacent pavement. <br />T -3e <br />23A -100 <br />
