Application of Balanced Mix Design Methodology to

The most common use of reclaimed asphalt pavement (RAP) is in the lower layers of a pavement structure, where it has been proven as a valid substitute for virgin materials. The use of RAP in surface mixes is more limited, since a major concern is that the high-RAP mixes may not perform as well as traditional mixes. To reduce risks or compromised performance, the use of RAP has commonly been ...

Optimizing the Use of Reclaimed Asphalt Pavement (RAP)

The approach is based on the results from three studies that looked at how to optimize the design of the mix, in terms of rutting and fatigue resistance, when more RAP is used. In the first study, a high RAP control mix and an optimized mix designed using different design compaction energy (65 and 50 gyrations respectively) were compared.

Asphalt Balanced Mix Design

Balanced mix design (BMD) for asphalt construction is used to design an optimum asphalt content between problems with rutting on one end and cracking on the other. Tests that are used to determine these parameters are the Hamburg wheel tracking test, the overlay test, the ideal cracking test and shear bond strength testing.
