The scarifying shall extend for 50 feet either side of the deficient <br /> area . <br /> 6 ) PRIME COAT <br /> A) The prime coat shall be a rapid curing liquid cut back asphalt equal or equivalent to RC40 or <br /> RC-250 at the Contractor' s option , and conforming to Sections 300 and 916 2 of the 1986 Edition <br /> of the Florida D . O . T . Standard Specifications for Road and Bridge Construction , <br /> B) The surface of the base material shall be cleaned after final compaction and the moisture content <br /> of the base shall not exceed 90 percent of the optimum moisture before the prime coat is applied . <br /> The prime coat shall be applied uniformly with a pressure distributor. The entire length of the <br /> spray bar shall be set at the height above the surface recommended by the Manufacturer for <br /> even distribution . The prime coat shall be applied to the finished base course at the rate of 0. 15 <br /> gallons per square yard at a temperature between 100 ° F . to 150 ° F . The prime coat shall be <br /> applied such that a period of no loner than two (2) hours lapse prior to application of the asphaltic <br /> concrete wearing course , unless the prune coat is covered with sand or screenings as outlined in <br /> Section 300-6 . 5 of the 1986 Edition of the Florida D . O . T . Specifications . <br /> 7 ) TESTING <br /> A) The maximum density and optimum moisture shall be determined in accordance with the <br /> Modified Proctor Test procedures of ASTM D1557 or AASHTO T180 ( Method D ) . The <br /> percentage compaction and in lace density shall be determined according to procedures of ASTM <br /> D2167 " Test for Density of Soil In Place by the Rubber Balloon Method " or the nuclear method <br /> ASTM D2922 . In general , one Modified Proctor Test per 300 lineal feet of roadwork shall be <br /> performed on a representative sample of base material from locations) designated by the <br /> Engineer . In place density testing shall be performed at the rate of one test per 300 lineal feet of <br /> roadwork or 5000 sq . ft . of parking area at comparable locations unless otherwise specified by <br /> the Engineer. <br /> RP-2-2 <br />
