Aggregates will be paid for by the number

13、 of metric tons tons square meters yards used in the accepted work. The recycling agent will be paid for by the number of liters gallons metric 2000-pound tons of material used in accepted work. The emulsified asphalt cement will be paid for by the number of liters gallons metric 2000-pound tons of

14、material used in accepted work. Determine the number of liters gallons of emulsified asphalt cement used either by measuring the material at a temperature of 15.6 degrees C 60 degrees F or by correcting the amount measured at another temperature to liters gallons at 15.6 degrees C 60 degrees F, usin
