Furnish the original to the Engineer at the plant and one copy to the Engineer at the paving site . Utilize any one of the following three electronic weigh systems : 320-2 .2 . 1 Electronic Weigh System on the Truck Scales : Provide an electronic weigh system on all truck scales , which is equipped with an automatic recordation system that is Iv approved by the Engineer. Use scales of the type that directly indicate the total weight of theIle r : loaded truck . Use scales meeting the requirements for accuracy, condition, etc . , of the Bureau of Weights and Measures of the Florida Department of Agriculture , and re-certify such fact every six months , either by the Bureau of Weights and Measures or by a registered scale technician . 320-2 .2 . 2 Electronic Weigh System on Hopper Beneath a Surge or Storage Bin : Provide an electronic weigh system on the hopper (hopper scales or load cells) beneath the surge or storage bin , which is equipped with an automatic recordation system approved by the Engineer. 320-2 .2 .3 Automatic Batch Plant with Printout : For batch plants , provide an approved automatic printer system which will print the individual or cumulative weights of aggregate and liquid asphalt delivered to the pugmill and the total net weight of the asphalt mix measured by hopper scales or load cell type scales . Use the automatic printer system only in conjunction with automatic batching and mixing control systems that have been approved by the Engineer. 320-2 .2 .4 Weekly Electronic Weigh System Comparison Checks : Check the accuracy of the electronic weighing system at the commencement of production and thereafter at ell least once a week during production by one of the following two methods : 320-2 .2 .4 . 1 . Electronic Weigh Systems on Truck Scales : Ll (a) The Engineer will randomly select a loaded truck of asphalt mix and record the truck number and gross weight from the Contractor ' s delivery ticket. (b) Weigh the selected truck on a certified truck scale , which is not owned by the Contractor and record the gross weight for the comparison check. If another certified truck scale is not available , the Engineer may permit another set of certified truck scales ke owned by the Contractor to be used . The Engineer may elect to witness the scale check. (c) The gross weight of the loaded truck as shown on the Contractor ' s delivery ticket will be compared to the gross weight of the loaded truck from the other certified truck scale . The maximum permissible deviation is 8 pounds per ton of gross weight of the loaded truck, based on the certified truck scale weight. (d) If the distance from the asphalt plant to the nearest certified 11 Fee truck scale is enough for fuel consumption to affect the accuracy of the comparison checks , a ere fuel adjustment may be calculated by using the truck odometer readings for the distance measurement, and 6 . 1 miles per gallon for the fuel consumption rate , and 115 ounces per gallon for fuel weight. (e) During production, when an additional certified truck scale is not available for comparison checks , the Engineer may permit the Contractor to weigh the truck on his certified scales used during production and then weigh it on another certified truck scale, as soon the other scale is available for the comparison checks . In addition to the periodic checks as specified above , check the scales at any time the accuracy of the scales becomes questionable . When such inaccuracy does not appear to be sufficient to seriously affect the weighing operations , the Engineer will allow a period of two calendar days for the Contractor to effect the required scales check .
