Bitumen Content - an overview | ScienceDirect Topics

Based on these results, dense and porous asphalt mixtures have been designed which incorporate PS by dry way (1 or 2% w/w of the total asphalt mixture), reducing the bitumen content accordingly. Satisfactory results have been obtained when the bitumen was replaced by 1% of PS, achieving good mechanical performance and even increasing the ...

VERIFYING THE ACCURACY OF HOT MIX PLANT ASPHALT METERS

EXAMPLE: If the project mixtures will normally be produced at 200 T/hr and the design asphalt content is 5.0% by weight, then the flow rate for the test run must be: 200 T/hr x 0.05 = 10 T/hr. For some plant control systems, it may be necessary to convert this to gallons per period. 6.4 Record the calibration setting of the meter adjuster.
