800 Fr,Tf 243 <br />ORDINANCE 95-10 <br />(c) A D.O.T.-approved bituminous prime coat of <br />grade RS -70 or RC -250 applied from ten - <br />hundredths to thirty-five hundredths of a <br />gallon per square yard. <br />(d) A compacted one -inch -thick D.O.T. Type II <br />asphaltic concrete surface course. <br />(e) <br />Testing of the above flexible pavement <br />construction shall be by an independent <br />testing laboratory approved by the public <br />works director or his designee <br />• The number of modified proctor <br />(AASHTO T-180) tests for subgrade and/or base <br />work shall be one for each material type. At <br />least two (2) FHV tests or one per ten <br />thousand (10,000) square feet of pavement, <br />whichever is greater, is required. At least <br />one in-place density test for every ten <br />thousand (10,000) square feet of pavement <br />using ASTM D2167 (rubber balloon method), sand <br />cone method, ASTM 2922 (nuclear method), or <br />other method as approved b the public works <br />director or his designee . is <br />required for both subgrade and base course <br />construction. A minimum of two (2) in-place <br />density tests are required regardless of size <br />of pavement areas. Soil -cement testing shall <br />be as per Florida Department of Transportation <br />Specifications. <br />(2) Rigid (concrete) pavement consisting of the <br />following (a) and (b): <br />(a) A six-inch thick subgrade stabilized to a <br />Florida bearing value of fifty (50) psi <br />minimum and compacted to a minimum of ninety- <br />eight (98) per cent maximum density using <br />AASHTO T-180. Testing shall be as for <br />flexible pavement above. <br />(b) For nonindustrial use, a four and one half- <br />inch -thick nonreinforced concrete pavement. <br />For industrial and frequent truck use, a <br />minimum six -inch -thick nonreinforced concrete <br />pavement. Design thickness for heavy <br />equipment use shall be in accordance with the <br />Portland cement Association recommendations. <br />Calculations shall be submitted to the ublic <br />works director or his designee • - . <br />with the request for rigid pavement design <br />showing the structural adequacy of the design <br />and the design life of the project. All <br />concrete to be three thousand (3,000) psi in <br />twenty-eight (28) days (AASHTO T023). All <br />materials, longitudinal, transverse and <br />construction joint location, material <br />placement, and finishing shall be as <br />recommended by the Portland cement Association <br />and the Concrete Promotional Council of <br />Florida. At least three (3) compressive <br />strength cylinder samples shall be taken for <br />26 <br />MAY 319 1995 <br />M M M <br />
