Arrange for the use of all non - public haul routes crossing the property of any railroad . incur any expense for the use of such haul routes . Establish haul routes which will direct construction vehicles away from developed areas when feasible , and keep noise from hauling operations to a minimum . Advise the Engineer in writing of all proposed haul routes . 120 -5 . 3 . 2 Borrow Material for Shoulder Build -up : When so indicated in the plans , furnish borrow material with a specific minimum bearing value , for building up of existing shoulders . Blend materials as necessary to achieve this specified minimum bearing value prior to placing the materials on the shoulders . Take samples of this borrow material at the pit or blended stockpile . 120 -5 . 4 Materials Used at Pipes , Culverts , etc . : Construct embankments over and around pipes , culverts , and bridge foundations with selected materials . 120- 6 Embankment Construction . 120 -6 . 1 General : Construct embankments in sections of not less than 300 feet in length or for the full length of the embankment . 120 -6 . 2 Dry Fill Method : 120 -6 . 2 . 1 General : Construct embankments to meet compaction requirements in Article 120 - 7 and in accordance with the acceptance program requirements in 120 - 9 . Restrict the compacted thickness of the last embankment lift to 6 inches maximum . As far as practicable , distribute traffic over the work during the construction of embankments so as to cover the maximum area of the surface of each layer . Construct embankment in the dry whenever normal dewatering equipment and methods can accomplish the needed dewatering . 120 -6 . 2 . 1 . 1 For A-3 and A-2 -4 Materials with up to 15 % fines : Construct the embankment in successive layers with lifts up to a maximum compacted thickness of 12 inches . Ensure the percentage of fines passing the No . 200 US Standard sieve in the A-2 -4 material does not exceed 15 % . 120 -6 . 2 . 1 . 2 For A- 1 Plastic materials (As designated in FDOT Design Standard Index 505 ) and A-24 Materials with greater than 15 % fines : Construct the embankment in successive layers with lifts up to a maximum compacted thickness of 6 inches . 120 -6 . 2 . 1 . 3 Equipment and Methods : Provide normal dewatering equipment including , but not limited to , surface pumps , sump pumps and trenching/ digging machinery . Provide normal dewatering methods including , but not limited to , constructing shallow surface drainage trenches/ditches , using sand blankets , sumps and siphons . When normal dewatering does not adequately remove the water , the Engineer may require the embankment material to be placed in the water or in low swampy ground in accordance with 120 -7 . 2 . 4 . 120 -6 . 2 . 2 Placing in Unstable Areas : Where depositing the material in water , or in low swampy ground that will not support the weight of hauling equipment , construct the embankment by dumping successive loads in a uniformly distributed layer of a thickness not greater than necessary to support the hauling equipment while placing subsequent layers . Once sufficient material has been placed so that the hauling equipment can be supported , construct the remaining portion of the embankment in layers in accordance with the applicable provisions of 120-7 . 2 . 4 and 120 - 7 . 2 . 6 . 24 Technical Specifications F :\Public Works\ENGINEERING DIVISION PROJECTS\0744-8th St-USI to 6th Ave\Admim\bid documents\0744 CONTRACT DOCUMENTS\Technical Specifications . doc
