ADDENDUM #1 120-9 Acceptance Program. 120-9.1 Density over 105%: When a computed dry density results in a value greater than 105% of the applicable Proctor maximum dry density, perform a second density test within 5 feet. If the second density results in a value greater than 105%, investigate the compaction methods, examine the applicable Maximum Density and material description. If necessary, test an additional sample for acceptance in accordance with AASHTO T 99, Method C. 120-9.2 Maximum Density Determination: Determine the maximum density and optimum moisture content by sampling and testing the material in accordance with the specified test method listed in 120-9.3 120-9.3 Density Testing Requirements: Ensure compliance with the requirements of 120-9.5 by Nuclear Density testing in accordance with FDOT Florida Method FM 1-T 238. Determine the in-place moisture content for each density test Use Florida Method FM 1-T 238, FM 5-507 (Determination of Moisture Content by Means of a Calcium Carbide Gas Pressure Moisture Tester), or ASTM D 4643 (Laboratory Determination of Moisture Content of Granular Soils By Use of a Microwave Oven) for moisture determination 120-9.4 Soil Classification: Perform soil classification tests in accordance with AASHTO T-88. Classify soils in accordance with AASHTO M-145 in order to determine compliance with embankment utilization requirements. 120-9.5 Acceptance Criteria: Obtain a minimum density in accordance with 120-7 2 with the following exceptions: 1) embankment constructed by the hydraulic method as specified in 120-6.3, 2) material placed outside the standard minimum slope as specified in 120-6.2.4; 3) other areas specifically excluded herein. 120-9.6 Frequency: Conduct sampling and testing at a minimum frequency listed in the table below Test Name Frequency Maximum Density One per soil type Density 1 per 500' RDWY (Alt Lift) Soil Classification One per Maximum Density 120-10 Maintenance and Protection of Work. While construction is in progress, maintain adequate drainage for the roadbed at all times. Maintain a shoulder at least 3 feet wide adjacent to all pavement or base construction in order to provide support for the edges. Maintain and protect all earthwork construction throughout the life of the Contract, and take all reasonable precautions to prevent loss of material from the roadway due to the action of wind or water. Repair any slides, washouts, settlement, subsidence, or other mishap which may occur prior to final acceptance of the work. Maintain all channels excavated as a part of the Contract work against natural shoaling or other encroachments to the lines, grades, and cross-sections shown in the plans, until final acceptance of the project 120-11 Construction. 120-11.1 Construction Tolerances: Shape the surface of the earthwork to conform to the lines, grades, and cross-sections shown in the plans In final shaping of the surface of earthwork, maintain a tolerance of 0.3 foot above or below the plan cross-section with the following exceptions 01025-32 Technical Specifications F \Public Works\ENGINEERING DIVISION PROJECTS \1205 -Vero Lake Estates Swk-87th St 101st Ave to CR510 (LAP)\Admim\ADDENDUMS\ADDENDUM 1\Technical Specifications Addendum #1 doc
