6.3 Determine the rate of asphalt flow. The rate must correspond to the mixture production rate anticipated to be most common during project production. 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.

219 CHAPTER 10 VERIFICATION OF PP2-99 PROTOCOL AASHTO DESIGNATION PP2-99: STANDARD PRACTICE FOR MIXTURE CONDITIONING OF HOT MIX ASPHALT INTRODUCTION This practice covers the accelerated aging (oxidation) of asphalt mix by means of elevated temperature. The test method is intended to simulate in-service oxidative aging of asphalt mix.

Research has shown that measuring the flexural stiffness of asphalt mixture beams using a bending beam rheometer (BBR) is a good way to control the low temperature properties of asphalt mixture s.
