i <br /> produced, then a new Gmm value will be determined from plant-produced mix, in accordance <br /> with FDOT Method FM 1-T 209, with the approval of the Engineer. Roadway density testing <br /> will not be required in certain situations as described in 334-6.4.1. Assure that the asphalt <br /> binder content, gradation and density test results meet the criteria in Table 334-4. <br /> Table 334-4 <br /> Process Control and Acce tance Values <br /> Characteristic Tolerance <br /> Asphalt Binder Content (percent) Target t 0.55 <br /> Passing No. 8 Sieve (percent) Target ± 6.00 <br /> Passing No. 200 Sieve (percent) Target t 2.00 <br /> Roadway Density (daily average) Minimum 90.0% of Gmm <br /> 334-6.4 Process Control Testing by the Contractor and Acceptance Testing by <br /> the Engineer: On Asphalt Work Category 3, perform process control testing as described in <br /> 334-6.3.1. In addition, the Engineer will accept the mixture at the plant with respect to <br /> gradation (P-s and P_20o)and asphalt binder content(Pb). The mixture will be accepted on the <br /> roadway with respect to density. The Engineer will sample and test the material as described <br /> in 334-6.3.1. The Engineer will randomly obtain at least one set of samples per day. Assure <br /> that the asphalt content, gradation and density test results meet the criteria in Table 334-4. <br /> Material failing to meet these acceptance criteria will be addressed as directed by the <br /> Engineer such as but not limited to acceptance at reduced pay, delineation testing to <br /> determine the limits of the questionable material, removal and replacement at no cost to the <br /> agency, or performing an Engineering analysis to determine the final disposition of the <br /> material. <br /> - 334-6.4.1 Acceptance Testing Exceptions:When the total quantity of any mix <br /> type in the project is less than 500 tons, the Engineer will accept the mix on the basis of visual <br /> inspection. The Engineer may run independent tests to determine the acceptability of the <br /> material. <br /> Density testing for acceptance will not be performed on widening strips or <br /> shoulders with a width of 5 feet or less,variable thickness overbuild courses, leveling courses, <br /> any asphalt layer placed on subgrade(regardless of type), miscellaneous asphalt pavement, <br /> shared use paths, crossovers, or any course with a specified thickness less than 1 inch or a <br /> specified spread rate less than 100 pounds per square yard. Density testing for acceptance <br /> Will not be performed on asphalt courses placed on bridge decks or approach slabs; compact <br /> these courses in static mode only. In addition, density testing for acceptance will not be <br /> performed on the following areas when they are less than 1,000 feet continuous in length: <br /> turning lanes, acceleration lanes, deceleration lanes, shoulders, parallel parking lanes, or <br /> ramps. Density testing for acceptance will not be performed in intersections.The limits of the <br /> intersection will be from stop bar to stop bar for both the mainline and side streets. Compact <br /> these courses in accordance with a standard rolling procedure approved by the Engineer. In <br /> the event that the rolling procedure deviates from the approved procedure, placement of the <br /> mix will be stopped. <br /> 334-7 Method of Measurement. <br /> For the work specified under this Section, the quantity to be paid for will be the weight <br /> of the mixture, in tons. <br /> 01025-44 Technical Specifications <br /> F:\Public Works\ENGINEERING DIVISION PROJECTS\1123 43rd Ave Sidewalk Improvements 26th St.to Airport Dr West\Admim\bid <br /> documents\Master Contract Documents\Technical Specifications.doc <br />
