If necessary, the sawing operations shall <br />be carried on both day and night, regardless of weather conditions. <br />All joints shall be sawed before uncontrolled shrinkage cracking occurs. A standby saw <br />shall be available in the event of breakdown. All weakened plane joints shall be saw cut <br />to a depth equal to one fourth of the pavement thickness. Longitudinal joint spacing shall <br />be at 10' minimum and 15' maximum on either side of centerline joint. Transverse joint <br />spacing shall be at 10' minimum and 15' maximum for pavement, curb and gutter. <br />Longitudinal joints shall be aligned such that they will cross manholes and water valves at <br />centerline if possible. Transverse construction joints within I'shall cross all manholes and <br />water valves. Provide a weakened plane joint around the perimeter of all utility vaults. <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 <br />following: <br />Tests <br />Sand Equivalent <br />Individual Test <br />Moving Average <br />Test Method <br />California 227 <br />Requirements <br />70 min <br />75 min <br />Evaluation of Sand Equivalent and Cleanness Value results shall conform to the provisions <br />of Standard Specifications Subsection 400-1.4. <br />Concrete shall be high early strength concrete, treated in accordance with section <br />201-1 to obtain (7) day compressive strength in (3) days. <br />Traverse joints shall match those of the adjacent pavement. The concrete pavement shall <br />be immediately barricaded upon its installation and no vehicular traffic will be permitted <br />until and after 3-days of placement and with the approval of the Engineer. <br />91 <br />
