What are the two main types of asphalt plant and what are the fundamental differences between them? 8. What is the function of the pugmill in a batch mix plant? 9. What are the main three distresses considered in the SuperPave binder specification system? What are the tests and performance parameters considered to judge the binder performance against these distresses? Explain the rationale behind selecting these performance parameters. 10. A binder tested at 64C using the DSR gave the following results: a. Unaged state: G* = 1000Pa and = 40 b. RTFO: G* = 1850Pa and =48 Determine if this binder passes the permanent deformation criteria at 64C. 11. What is the significance and the use of each one of these tests: a. RTFO procedure b. Rotational viscometer test c. Dynamic shear rheometer...
