L <br /> The surface of the base material shall be cleaned after final compaction and the moisture content of <br /> the base shall not exceed 90 percent of the optimum moisture before the prime coat is applied. The <br /> prime coat shall be applied uniformly with a pressure distributor. The entire length of the spray bar <br /> shall be set at the height above the surface recommended by the Manufacturer for even distribution. <br /> The prime coat shall be applied to the finished base course at the rate of 0 . 15 gallons per square yard <br /> at a temperature between 100°F to 150°F. The prime coat shall be applied such that a period of no <br /> longer than two (2) hours lapse prior to application of the asphaltic concrete wearing course, unless <br /> the prime coat is covered with sand or screenings as outlined in Section 300-6 . 5 of the 2002 Edition <br /> of the Florida D .O .T. Specifications. <br /> 3 . 04 TESTING <br /> The maximum density and optimum moisture shall be determined in accordance with the Modified <br /> Proctor Test procedures of ASTM-D1557 or AASHTO-T180 (Method D). At a minimum, one ( 1 ) <br /> Modified Proctor Test shall be performed for each 10,000 square feet of base material on <br /> representative samples from location(s) designated by the Engineer. The percentage compaction and <br /> in-place density shall be determined according to procedures of ASTM-132167 "Test for Density of <br /> Soil In-Place by the Rubber Balloon Method" or the nuclear method ASTM- D2922. In-place <br /> density testing shall be performed at a minimum rate of four (4) Modified Proctor tests per 10,000 <br /> square feet of area to be paved unless quality control measures allow the Engineer to dictate fewer <br /> tests. Smaller projects shall require a minimum of two (2) test locations. <br /> I L END OF SECTION <br /> L <br /> L <br /> a <br /> L <br /> 02722 — Cemented Coquina Shell Base <br /> r 02722 - 3 <br /> L <br />
