Permanent pavement repair shall be in accordance with the details shown in the Standard <br />Details herein, with edges straight and parallel and patches rectangular in plan. Any paving <br />replacement required, beyond the limits shown in the details and as called for in the <br />Specifications, shall be at the Contractor's expense. Where trenches are located out of the <br />existing pavement and damage occurs to the pavement, that pavement shall also be <br />replaced by the Contractor at his expense. <br />B. Pavement markings removed or obliterated by the Contractor's operations shall be promptly <br />replaced, in kind, and paid for under the appropriate bid item as provided in the proposal, <br />to the satisfaction of the Miami-Dade County Department of Transportation and Public <br />Works, Traffic Engineering Division, or other authority having jurisdiction over the work <br />area. No payment will be made for pavement marking replacement outside of construction <br />limits as described herein. <br />C. All equipment necessary for construction shall be on the job site in first class working <br />condition. Spilling or dropping of petroleum products is prohibited and all defective <br />equipment shall be removed or replaced immediately. The Contractor shall be subject to <br />all DERM (Department of Environmental Resources Management) regulations and clean up <br />requirements. <br />D. The percentages of maximum density for subgrade and limerock base specified herein are <br />minimum. Greater percentages of maximum density shall be obtained, if so required, by <br />the governing authority having jurisdiction over the work location. <br />E. Asphaltic concrete mixtures shall be obtained only from plants, which comply with the <br />requirements of FDOT Specifications, Section 320 as applicable, using materials specified <br />herein, and producing the specified mixture. General construction requirements for all hot <br />bituminous mixtures specified herein shall conform to DOT Specifications, Section 330, as <br />applicable. <br />F. Asphaltic concrete shall be laid only where the surface to be covered is intact, firm, cured <br />and dry, and only when weather conditions are suitable. The temperature of the mixture <br />at the time of spreading shall be within limits of Florida DOT specifications or within <br />25 degrees of the temperature set by the Department. No mixture shall be spread when <br />the air temperature is less than 40 degrees Fahrenheit. <br />G. Any mixture caught in transit by a sudden rain may be laid at the Contractor's risk, if the <br />base is in suitable condition. Under no circumstances shall asphaltic material be placed while <br />rain is falling, or when there is water on the area to be paved. <br />H. Subgrade: Roadway subgrades shall be stabilized to the minimum depth shown on the <br />Drawings to a Limerock Bearing Ratio of not less than 40. Stabilizing shall be Type B as <br />defined in Section 160 of the DOT Specifications. Stabilization may require the addition <br />and thorough mixing in of crushed limerock, course limerock screenings, or any other <br />stabilizing material acceptable to the Department. The stabilizing material shall be applied <br />in such quantity that, after mixing and blending, the subgrade will have a LBR of not less <br />than 40. Stabilizing material shall be mixed or blended in the subgrade material by plowing, <br />scarifying, disking, harrowing, blading and mixing with rotary tillers until the mixed <br />materials are of uniform bearing value throughout the width and depth of the layer being <br />processed.
