The quantity of asphaltic emulsion is the weight determined before the addition of any water. The weight of asphaltic emulsion is determined from volumetric measurements if:
1.Partial loads are used
2.Scale is not available within 20 miles
3.Asphaltic emulsion is delivered in: 3.1. Trucks with each tank calibrated and accompanied by its measuring stick and calibration card SECTION 94 ASPHALTIC EMULSIONS 3.2. Trucks equipped with a vehicle tank meter and a calibrated thermometer that determines the asphalt temperature at delivery For volumetric measurements, the measured volume of asphaltic emulsion is reduced to the volume the material would occupy at 60 degree s F. One ton of asphaltic emulsion at 60 degrees F equals 240 gal. One gallon of asphaltic emulsion at 60 degrees F equals 8.33 lb.
