The objective of this research effort is to compare the laboratory performance of
Nevada’s HMA mixtures made with rubber modified asphalt binders with HMA mixtures made
with polymer modified binders. Two Nevada HMA mixtures are used in the study: one mix
from the south and one mix from the north. Each mix was designed with the two types of
binders which resulted in a total of four HMA mixtures that were evaluated in the study. The
laboratory performances of the mixtures are evaluated in terms of the following properties:
Moisture sensitivity
Dynamic modulus
Resistance to rutting
Resistance to fatigue cracking
Resistance to thermal crackin
