120-9 Acceptance Program. <br /> 120 -9 . 1 Density over 105 % : When a computed dry density results in a value greater <br /> than 105 % of the applicable Proctor maximum dry density , perform a second density test <br /> within 5 feet . If the second density results in a value greater than 105 % , investigate the <br /> compaction methods , examine the applicable Maximum Density and material description . If <br /> necessary , test an additional sample for acceptance in accordance with AASHTO T 99 , <br /> Method C . <br /> 120 -9 . 2 Maximum Density Determination : Determine the maximum density and <br /> optimum moisture content by sampling and testing the material in accordance with the <br /> specified test method listed in 120 - 9 . 3 . <br /> 120 -9 . 3 Density Testing Requirements : Ensure compliance with the requirements of <br /> 120 -9 . 5 by Nuclear Density testing in accordance with FDOT Florida Method FM 1 -T 238 . <br /> Determine the in - place moisture content for each density test . Use Florida Method <br /> FM 1 -T 238 , FM 5- 507 ( Determination of Moisture Content by Means of a Calcium Carbide <br /> Gas Pressure Moisture Tester) , or ASTM D 4643 ( Laboratory Determination of Moisture <br /> Content of Granular Soils By Use of a Microwave Oven ) for moisture determination . <br /> 120 -9 . 4 Soil Classification : Perform soil classification tests in accordance with <br /> AASHTO T- 88 . Classify soils in accordance with AASHTO M - 145 in order to determine <br /> compliance with embankment utilization requirements . <br /> 120 -9 . 5 Acceptance Criteria : Obtain a minimum density in accordance with 120 - 7 . 2 <br /> with the following exceptions : <br /> 1 ) embankment constructed by the hydraulic method as specified in 120 -6 . 3 ; <br /> 2 ) material placed outside the standard minimum slope as specified in <br /> 120 -6 . 2 . 4 ; <br /> 3 ) other areas specifically excluded herein . <br /> 120 -9 . 6 Frequency : Conduct sampling and testing at a minimum frequency listed in <br /> the table below . <br /> Test Name Frequency <br /> Maximum Density One per soil type <br /> Density 1 per 500 ' RDWY Alt Lift <br /> Soil Classification One per Maximum Density <br /> 120- 10 Maintenance and Protection of Work. <br /> While construction is in progress , maintain adequate drainage for the roadbed at all <br /> times . Maintain a shoulder at least 3 feet wide adjacent to all pavement or base construction <br /> in order to provide support for the edges . <br /> Maintain and protect all earthwork construction throughout the life of the Contract , and <br /> take all reasonable precautions to prevent loss of material from the roadway due to the action <br /> of wind or water. Repair any slides , washouts , settlement , subsidence , or other mishap which <br /> may occur prior to final acceptance of the work . Maintain all channels excavated as a part of <br /> the Contract work against natural shoaling or other encroachments to the lines , grades , and <br /> cross- sections shown in the plans , until final acceptance of the project . <br /> 120- 11 Construction . <br /> 120 - 11 . 1 Construction Tolerances : Shape the surface of the earthwork to conform to <br /> the lines , grades , and cross-sections shown in the plans .
