A Laboratory Evaluation on the
use of Recycled Asphalt Pavements in HMA Mictures
The laboratory experiment documented in this report was conducted to
answer the following questions:
- Can the RTC’s Marshall Mix Design method be used to design HMA mixtures containing
15 and 30% RAP?
- Is the mixing process of virgin and RAP materials effective in producing a final binder
meeting the target binder grade?
- Can the blending chart method be used to determine the grade of the virgin binder
required for a given combination of RAP source and RAP content?
- What impact does the RAP source and content have on the following properties of the
final mix:
Moisture sensitivity, Resistance to rutting, Resistance to fatigue
cracking and Resistance to thermal cracking
- Can the resilient modulus property be used as a surrogate test to estimate the
performance of HMA mixtures containing RAP?
